Language and Human Language

Introduction

Language is a system of communication that enables humans to convey thoughts, emotions, and ideas. It is perhaps the most sophisticated and defining feature of our species. Human language, with its unique properties and structures, allows for an extraordinary range of expression that distinguishes it from the communication systems of other species. Here, we will explore the nature of language, its defining characteristics, and the cognitive and social functions it serves. Moreover, the origins of human language, the process of language acquisition, and the relationship between language and thought will be investigated. By drawing on the insights of linguists and scholars, this account will demonstrate how language forms the foundation of human identity and culture.

Language is not only a means of communication but also a cognitive and social tool that shapes the way we perceive the world and interact with others. As linguists like Edward Sapir famously stated, “Language is a guide to social reality” (Sapir 1929). This quote highlights how central language is to our understanding of the world and our place within it. Therefore, this section will shed light on the importance of language in human evolution, thought, and social dynamics.

Defining Language

Language can be broadly defined as a structured system of signs, sounds, symbols, or gestures used for communication. However, this general definition does not capture the full complexity of human language. Linguists like Ferdinand de Saussure were instrumental in conceptualizing language as a system of signs that operate within a social framework. According to Saussure, language is composed of two fundamental elements: the signifier (the sound or form) and the signified (the concept or meaning). Together, these form a sign, and language consists of a vast array of signs that allow for meaningful communication (Saussure 1916).

Saussure’s theory of semiotics (the study of signs) became foundational in modern linguistics, emphasizing the arbitrary relationship between words and their meanings. For instance, there is no inherent reason why the word “dog” should represent the animal. The connection between the signifier and signified is arbitrary, and this arbitrariness is a key feature of human language.

Beyond Saussure’s structuralist view, Noam Chomsky’s generative grammar theory offers another important perspective on language. Chomsky argues that language is a rule-governed system that allows for an infinite number of expressions using a finite set of rules. In his seminal work, Syntactic Structures (1957), Chomsky introduced the idea of “rule-governed creativity,” which suggests that speakers can produce and comprehend sentences they have never heard before, thanks to their internalized knowledge of linguistic rules.

Thus, language is both a system of symbols and a cognitive mechanism for generating endless possibilities of expression. It is a tool that enables humans to navigate the complexities of the world and interact with others in a way that no other species can. The following definitions illustrate the points.

·       A language is a system of arbitrary vocal symbols by means of which the members of a society interact in terms of their total culture. (Trager 1949).

·       A language is a set (finite or infinite) of sentences, each finite in length and constructed of a finite set of elements. (Chomsky 1957).

·       Language is the institution whereby humans communicate and interact with each other by means of habitually used oral-auditory arbitrary symbols. (Hall 1964).

·       Audible, articulate meaningful sounds as produced by the action of the vocal organs. (Webster’s Third New International Dictionary, Vol. 2, 1971).

·       Language is the most sophisticated and versatile means available to human beings for the communication of meaning. (Brown 1984).

·       Language is a patterned system of arbitrary sound signals, characterized by structure dependence, creativity, displacement, duality, and cultural transmission. (Aitchison 1987).

·       Language is a system of communication in which meanings are conveyed through the use of sounds, symbols, and gestures according to rules. (Crystal 1992).

·       Language is a purely human and non-instinctive method of communicating ideas, emotions, and desires by means of a system of voluntarily produced symbols. (Sapir 1921).

·       Language is a finite system of elements and principles that make it possible for speakers to construct sentences to express thoughts and ideas. (Pinker 1994).

·       Language is a system of symbols with standardized meanings through which we communicate ideas and emotions. (Lyons 1977).

Language is governed by several key components, including:

Ø  Phonetics and Phonology: Phonetics deals with the sounds of speech, while phonology focuses on how these sounds are organized within a particular language. For example, the “p” sound in “pat” differs from the “p” sound in “spat,” even though they are perceived as the same sound by speakers of English. Phonology studies such differences and how they function within languages.

Ø  Morphology: Morphology concerns the structure of words and how they are formed. For example, the English word “unhappiness” consists of three morphemes: “un-” (a prefix indicating negation), “happy” (the root), and “-ness” (a suffix turning the adjective into a noun).

Ø  Syntax: Syntax deals with how words are combined to form sentences. The order of words in a sentence affects its meaning. For instance, “The dog chased the cat” and “The cat chased the dog” contain the same words but convey different meanings due to their syntactic arrangement.

Ø  Semantics: Semantics is the study of meaning in language. It examines how words and sentences convey meaning and how interpretations can vary depending on context.

Ø  Pragmatics: Pragmatics goes beyond literal meanings to study how language is used in specific contexts. For example, the phrase “Can you pass the salt?” is usually interpreted as a polite request rather than a literal question about someone’s ability to pass the salt.

Human Language

Language is a complex system used for communication that consists of structured rules (grammar) and a collection of words (vocabulary) that allow people to express thoughts, ideas, and emotions. It is not limited to speech but also includes writing and visual symbols, such as sign language. A defining characteristic of human language is its flexibility—it can be spoken, written, or signed, adapting to different cultures and times. Human language relies on shared social conventions and is learned through education. Unlike animal communication systems, which are usually fixed, human language is endlessly productive and creative.

Unique Features of Human Language

One of the most significant questions in linguistics is what distinguishes human language from the communication systems used by other species. To address this, Charles Hockett proposed a list of “design features” that are unique to human language. These features help linguists understand why human communication is so much more versatile and complex than the signalling systems used by animals.

Ø  Reflexivity

Reflexivity refers to our ability to use language to reflect on language itself. This unique feature of human language allows us to think, talk, and analyze how language works.

When we ask questions like “What does this word mean?” or discuss how to form a sentence, we are using reflexivity. We are not only using language to communicate with others but also to understand language itself.

Ø  Displacement

Displacement refers to the ability to discuss things that are not immediately present in the environment. Human language allows us to talk about the past, the future, hypothetical situations, and abstract concepts like love, justice, or freedom. This capacity for displacement sets human language apart from most animal communication systems, which tend to be limited to the here and now. For instance, a dog may bark to signal danger, but it cannot communicate a plan for future actions or reminisce about past experiences. When you tell someone, “I will meet you next week at the coffee shop,” you are using displacement to refer to a future event. Similarly, you can discuss concepts like “heaven,” “dinosaurs,” or fictional characters that do not exist in the present moment.

Displacement is crucial in human social interactions because it allows for planning, storytelling, and the transmission of knowledge across generations. Linguist Steven Pinker describes this as a “mental time travel” that enhances cooperation and learning within human communities (Pinker 1994).

Ø  Arbitrariness

Human language is characterized by the arbitrary relationship between words (or signs) and their meanings. As Saussure highlighted, the sounds of words do not have any intrinsic connection to the objects or ideas they represent. For example, there is no logical reason why the sequence of sounds “tree” should represent the concept of a large, leafy plant. This arbitrariness is what allows languages to vary widely in their sounds and structures, depending on cultural and historical contexts. For example, the word “apple” has no direct or natural link to the fruit itself. In English, we use “apple,” while in French, the word is “pomme,” and in Spanish, it is “manzana.” Each language chooses its own arbitrary symbols to convey meaning.

Animal communication, on the other hand, often relies on signals that have a direct, non-arbitrary connection to their meaning. For example, the waggle dance of bees directly correlates with the direction and distance of food sources. In contrast, human language’s arbitrary nature makes it more flexible and adaptable, capable of expressing an infinite variety of ideas.

Onomatopoeia as an Exception: Some words, like “buzz” or “bang,” imitate the sounds associated with what they represent. These are called onomatopoeic words, but they are the exception rather than the rule. Most words do not have a natural relationship with their meanings.

Ø  Productivity

Productivity, also referred to as creativity, is the ability of language users to create and understand new sentences that they have never heard before. This feature is linked to the generative nature of language, as described by Chomsky. Human language allows for an unlimited number of expressions by combining words and grammatical rules in novel ways. For example, a person can create a sentence such as “The purple dragon flew over the rainbow while singing a lullaby,” even though it is unlikely anyone has ever heard or said that sentence before.

This ability to generate new ideas and communicate them is central to human creativity, innovation, and intellectual development. It also highlights the recursive nature of human language, where smaller units of meaning (words) can be combined into larger, more complex structures (sentences).

Ø  Duality of Patterning

Duality of patterning refers to the organization of language at two levels: sounds (phonemes) and meanings (morphemes). At the first level, a small set of phonemes is combined in various ways to create morphemes, which are the smallest units of meaning. These morphemes, in turn, combine to form words and sentences.

This feature allows human languages to be incredibly efficient and flexible. A relatively small number of sounds can be used to generate an immense vocabulary, and these words can be further combined to produce an infinite variety of sentences. This duality of patterning is unique to human language and is not observed in the communication systems of other species.

Ø  Cultural Transmission

Language is not passed down genetically; it is learned through social interaction. This process of learning is known as cultural transmission. Children acquire the language (or languages) spoken by their caregivers and community through exposure and interaction, not through biological inheritance. This feature of human language is what allows it to evolve and change over time, as new generations modify and adapt the language they learn.

In contrast, many animal communication systems are innate rather than learned. For example, the calls of certain birds are genetically hardwired, meaning that they do not need to be taught to produce them. Human language, however, is deeply intertwined with culture, and the specific language a person learns is shaped by their social environment.

Ø  Specialization

Specialization refers to the use of language to replace physical actions with verbal commands or expressions, allowing for more efficient and sophisticated communication.

For instance, if a child yells “Stay away!” at a friend, the words alone are enough to convey the message without needing to physically push the friend away. Similarly, when a police officer says “Move along!” to a crowd, they don’t have to physically move people; the verbal command is enough to communicate the instruction.

Ø  Interchangeability

Interchangeability means that human language allows both the sender and receiver of a message to switch roles. In a conversation, any person can both speak (send a message) and listen (receive a message). This fluid exchange is central to human communication.

During a conversation, one person may ask a question, and the other may respond, with the roles of speaker and listener alternating.

Additional Features

Ø  Vocal-Auditory Channel: Human verbal communication is primarily produced by the vocal organs and received through the ears. This channel allows speech to be transmitted as sound from the speaker to the listener. While most human communication occurs this way, language can also be conveyed without sound, such as through writing. Interestingly, many animals, like dolphins, also use the vocal-auditory channel for communication.

Ø  Directional Reception and Broadcast Transmission: When we speak, the sound waves spread out in all directions, making it possible for anyone nearby to hear the message. At the same time, our ears are equipped to locate the source of the sound, enabling us to identify who is speaking and where they are.

Ø  Total Feedback: When speaking, humans can hear and monitor their own speech, allowing them to reflect on and adjust what they are saying. This ability to self-monitor while communicating helps maintain clarity. In contrast, visual displays (like gestures) don’t always provide this kind of immediate feedback to the person displaying them.

Ø  Rapid Fading: Spoken language is fleeting—once the words are said, they disappear almost instantly and cannot be preserved in the air like written text or a visual signal. Auditory communication, unlike writing or some animal signals, doesn’t wait for the listener’s convenience and must be heard in real-time to be understood.

These features highlight the extraordinary complexity of human language and demonstrate why it is fundamentally different from other forms of communication found in the animal kingdom.

The Origins of Language

The origins of language have been the subject of much debate and speculation. While it is impossible to pinpoint exactly when and how language first evolved, several theories offer insights into its possible origins.

Ø  Biological Evolution

One of the leading theories regarding the origin of language is that it evolved as a biological adaptation unique to humans. Steven Pinker, in The Language Instinct (1994), argues that language is an innate faculty that evolved through natural selection. According to this view, the human brain has specialized mechanisms for language acquisition, making it possible for us to learn and use language effortlessly.

Pinker suggests that language evolved as a survival tool, enabling early humans to communicate complex ideas, coordinate social activities, and share knowledge. The ability to use language would have given humans a distinct evolutionary advantage, allowing for more effective cooperation and problem-solving.

Ø  Universal Grammar

Noam Chomsky’s theory of universal grammar offers another perspective on the origins of language. Chomsky argues that all human languages share a common underlying structure, known as universal grammar. According to this theory, humans are born with an innate ability to acquire language because of a “language acquisition device” in the brain. This device provides the basic framework for learning any language, and the specific language a person learns depends on their environment (Chomsky 1965).

Chomsky’s theory explains why children can easily learn the language of their community, regardless of which language it is. He suggests that the capacity for language is hardwired into the human brain, a view that has influenced much of modern linguistics.

Ø  Gesture Theory

Another theory about the origins of language is that it evolved from manual gestures. Michael Corballis, in his work From Hand to Mouth: The Origins of Language (2002), argues that early human communication likely involved a combination of gestures and vocalizations. Corballis suggests that before the development of spoken language, humans may have used hand movements to convey meaning, similar to the way sign languages are used today.

Over time, these gestures may have been supplemented by vocal sounds, eventually leading to the development of fully articulated speech. Corballis’s theory is supported by research on the brain’s mirror neuron system, which is involved in both the production of gestures and the understanding of others’ actions.

This idea that language may have evolved from gestural communication is also supported by the fact that many modern human languages incorporate gestures and body language as part of communication.

Ø  Social and Cultural Theories

Some scholars argue that language evolved as a social and cultural phenomenon rather than solely as a biological adaptation. Robin Dunbar’s “social brain hypothesis” suggests that language evolved to facilitate social bonding in large groups. According to Dunbar, early humans needed a way to maintain social cohesion and manage complex relationships, and language provided a way to achieve this (Dunbar 1996).

Language, in this view, is a tool for building social networks and maintaining alliances. It allows individuals to share information, gossip, and negotiate relationships in a way that non-verbal communication systems could not. Thus, the evolution of language is closely tied to the social needs of early human communities.

Language Acquisition

Language acquisition is the process by which humans learn to understand and produce language. This process occurs rapidly in young children, who can learn the grammar and vocabulary of their native language by the age of three, without formal instruction. Children’s language acquisition typically follows a predictable sequence of stages, beginning with the babbling phase, progressing to the one-word stage, and eventually reaching the stage of complex sentences. During the babbling stage, infants produce a wide range of sounds, many of which are not specific to their native language. This phase is followed by the one-word stage, during which children begin to associate sounds with meanings and produce single words to communicate.

As children’s linguistic abilities develop, they move to the two-word stage, where they begin combining words to form simple sentences such as “want juice” or “big dog.” This is followed by the telegraphic stage, in which children produce more complex sentences that lack grammatical morphemes, much like a telegram (e.g., “Daddy go work”).

Ø  Nativist Perspective: Chomsky’s theory of universal grammar suggests that children are born with an innate ability to acquire language. He posits that the brain is equipped with a “language acquisition device” that allows children to effortlessly learn the rules of grammar, regardless of the specific language they are exposed to (Chomsky 1965).

Ø  Interactionist Perspective: Michael Tomasello offers a contrasting view, arguing that language acquisition is driven by social interaction. He believes that children learn language by engaging with their caregivers in meaningful communication, with the environment playing a critical role in shaping language development (Tomasello 2003).

Ø  Critical Period Hypothesis: One of the most widely discussed theories in language acquisition is the critical period hypothesis, which suggests that there is a specific window of time during which language acquisition occurs most easily. This hypothesis was first proposed by Eric Lenneberg in his book Biological Foundations of Language (1967), where he argued that children are particularly adept at learning language before puberty, after which it becomes significantly more difficult. The critical period hypothesis is supported by evidence from studies of feral children—children who were raised without exposure to language. These studies show that children who are not exposed to language during the early years of life often struggle to acquire it later, even with intensive instruction.

Language and Animal Communication

While many animals use communication systems, these systems differ significantly from human language. Animal communication is typically limited to expressing immediate needs or emotions, whereas human language allows for abstract thought, displacement, and productivity.

Ø  Primates and Language: Researchers have attempted to teach language to primates, with varying degrees of success. For example, chimpanzees like Washoe and bonobos like Kanzi have been taught to use sign language and lexigrams to communicate. However, while these animals can learn basic symbols, their use of language lacks the grammatical complexity and generative capacity of human language (Savage-Rumbaugh et al. 1998).

Ø  Birdsong: Birds, particularly songbirds, use vocalizations that are sometimes compared to human language. Like human language, birdsong involves learning complex sequences of sounds and is passed down through cultural transmission. However, birdsong lacks the productivity and semantic richness of human language (Marler 1970).

Functions of Language

Language is a multifaceted phenomenon that serves many functions. Over time, linguists have explored these functions to better understand how communication works. One influential linguist, Roman Jakobson, identified six primary functions of language that help describe how verbal communication operates effectively. These six functions are as follows:

Ø  The Referential Function:

The referential function is used to convey factual information, which was one of the key reasons why language was first developed. It enables descriptions of situations, objects, and even mental states. When we report on the world around us or describe what we are thinking, we are using the referential function of language. For instance, when we say, “The sky is blue,” we are providing information about the environment.

Ø  The Expressive Function:

The expressive function focuses on conveying the speaker’s or writer’s emotions and attitudes. This function can also evoke feelings in the listener or reader. Often, this form of communication is used to express personal reactions, and it can occur even when we are alone. For example, if someone accidentally drops their phone into water, they might spontaneously express their frustration by swearing. On the other hand, people can use the expressive function to communicate positive emotions, such as when they see something beautiful and exclaim, “Wow, isn’t that amazing!”

Ø  The Directive Function:

The directive function directly engages the listener and is used to cause or prevent certain actions. This function often appears in commands, requests, and instructions, and it requires the use of imperative language. Examples include, “Adit, come here immediately,” or “Please close the door.” The purpose here is to direct someone’s behaviour.

Ø  The Phatic Function:

The phatic function is used to maintain social interaction. This function helps establish and reinforce connections between people, often through greetings or small talk. Phrases like “Hello, how are you?” or casual remarks about the weather, such as “It’s been really hot lately,” serve this purpose. The primary goal here is not to exchange information but to build or sustain social relationships.

Ø  The Poetic Function:

The poetic function emphasizes the form and beauty of the message itself. This function is often found in literature, poetry, slogans, and other aesthetic uses of language. Here, the focus is on how the message is crafted, rather than its content. In poetry or advertising, for example, the choice of words, rhythm, and style all contribute to this function.

Ø  The Metalingual Function:

The metalingual function refers to the use of language to talk about language itself. When we explain grammar rules, discuss the meaning of a word, or analyze a text, we are engaging in metalingual communication. This function is essential in teaching, learning, and understanding language, as we often need to clarify or analyze how language operates.

It’s important to note that in most cases, a piece of communication does not serve just one function. Rather, language is typically multifunctional. Even everyday conversations often mix several of these functions to achieve effective communication. For instance, a simple conversation may combine referential information, expressive emotions, and phatic social interaction, all at the same time. Thus, Jakobson’s framework helps us understand the diverse ways in which language operates in our daily lives.Top of FormBottom of Form

Cognitive Functions of Language

Language serves cognitive functions. Cognitively, it helps us categorize the world, express thoughts, and process complex information. Linguists like George Lakoff and Mark Johnson, in their seminal work Metaphors We Live By (1980), argue that language is central to thought and that many of our abstract ideas are shaped by metaphors grounded in physical experience.

Ø  Language and Thought

The relationship between language and thought has been a subject of philosophical inquiry for centuries. Linguists such as Edward Sapir and Benjamin Lee Whorf explored this connection through the Sapir-Whorf hypothesis, which posits that language influences thought and perception.

• Linguistic Relativity

The strong version of the Sapir-Whorf hypothesis, known as linguistic determinism, suggests that language determines the way individuals think. In this view, speakers of different languages experience the world in fundamentally different ways because their languages shape their thoughts. For example, Whorf argued that the Hopi language, which lacks tense markers for time, reflects a different conception of time compared to languages that distinguish between past, present, and future (Whorf 1956).

While the strong version of the Sapir-Whorf hypothesis has been largely discredited, the weaker version, known as linguistic relativity, remains influential. Linguistic relativity suggests that language influences thought, but it does not determine it. For example, research has shown that speakers of languages with gendered nouns, such as Spanish or German, may think about objects differently based on their grammatical gender. Moreover,  languages that have many words for snow may shape how speakers of those languages experience snow.

• The Debate on Universalism vs. Relativism

The debate between linguistic universalism and linguistic relativism centres on whether language shapes thought or whether there are universal cognitive structures that influence language. Universalists, such as Chomsky, argue that all human languages share a common underlying structure, and cognitive processes are similar across linguistic groups. Relativists, on the other hand, argue that language shapes thought and that speakers of different languages may perceive and understand the world in unique ways.

This debate continues to influence research in psycholinguistics and cognitive science, as scholars investigate how language, culture, and cognition intersect.

Social Functions of Language

Language plays a crucial role in shaping identity and facilitating social interaction. It is not only a means of communication but also a marker of group identity and cultural heritage.

Ø  Language and Identity

Language is often closely tied to a person’s identity, particularly in multilingual societies where language choice can signal membership in a particular cultural or ethnic group. As sociolinguist William Labov points out, “Language is an instrument of social control and a means of establishing and maintaining social boundaries” (Labov 1972). Through language, individuals express their belonging to a particular group and differentiate themselves from others.

Bilingualism and code-switching are common phenomena in multilingual societies, where speakers may switch between languages or dialects depending on the social context. This ability to navigate multiple linguistic identities is often seen as a marker of social and cultural competence.

William Labov have also shown that language is a powerful marker of social identity. The way people speak, their accent, and their use of dialect can signal their social status, ethnicity, or regional origin. Code-switching, or the practice of shifting between different languages or dialects depending on the social context, further highlights the social function of language in managing identity.

·       Linguistic Imperialism: Robert Phillipson’s theory of linguistic imperialism argues that the spread of dominant languages, such as English, often comes at the expense of minority languages. He asserts that the global dominance of English has led to the marginalization of indigenous languages and cultures, particularly in former colonial regions (Phillipson 1992).

·       Code-Switching: Code-switching is a practice observed in bilingual or multilingual individuals who switch between languages or dialects in different social contexts. Sociolinguists argue that this practice reflects speakers’ negotiation of their identities, as they adapt their language use to different cultural or social settings (Gumperz 1982).

Ø  Language and Social Power

Language is also a powerful tool for shaping social hierarchies and maintaining systems of power. Sociolinguists such as Pierre Bourdieu and Robert Phillipson have argued that language can be used to legitimize social inequalities and reinforce dominant ideologies. Phillipson, in his book Linguistic Imperialism (1992), discusses how colonial powers used language policies to assert dominance over indigenous populations, often promoting the languages of colonizers at the expense of local languages.

In contemporary society, the dominance of English as a global language raises questions about linguistic imperialism and the erosion of minority languages. While English has become the lingua franca of international communication, its spread has also led to the decline of many smaller languages, putting linguistic diversity at risk.

The Future of Human Language

As we move further into the 21st century, new developments in technology, globalization, and social change are reshaping the way humans use language. The rise of the internet, social media, and artificial intelligence has introduced new forms of communication that challenge traditional linguistic norms.

Ø  Language and the Internet

The internet has revolutionized human communication, allowing people from different parts of the world to interact in real time. David Crystal, in Language and the Internet (2006), explores how digital communication has given rise to new linguistic practices, such as text messaging, emojis, and online slang. These forms of communication often blur the boundaries between spoken and written language, creating a dynamic and evolving linguistic landscape.

While some linguists worry that digital communication is eroding language skills, others argue that it represents a new form of linguistic creativity. The internet allows for the rapid spread of new words and expressions, and online communities often develop their own linguistic norms and conventions.

Ø  The Endangered Languages Crisis

Despite the global dominance of languages like English, many of the world’s languages are endangered. According to Michael Krauss, up to 90% of the world’s languages could disappear within the next century (Krauss 1992). The loss of these languages represents not only a loss of linguistic diversity but also a loss of cultural heritage, as many endangered languages are closely tied to specific cultural traditions and worldviews.

Efforts to preserve and revitalize endangered languages are underway in many parts of the world. Indigenous communities, linguists, and activists are working together to document and teach these languages to future generations. The survival of these languages is crucial for maintaining linguistic and cultural diversity in a rapidly changing world.

Conclusion

Human language is a complex and multifaceted phenomenon that touches on nearly every aspect of human life. It is a tool for communication, a vehicle for thought, and a marker of identity. From its biological origins to its social functions, language continues to be a subject of fascination and inquiry for linguists, anthropologists, and cognitive scientists.

As we continue to explore the intricacies of language, we gain a deeper understanding of what it means to be human. Language is not only a means of expressing ideas but also a key to understanding our shared humanity, our individual identities, and the cultures we inhabit.
