Introducing Linguistics

1. Linguistics: A Scientific Journey into Language Structure

Human beings have probably been speaking for as long as we have existed, but it was only around 3,000 years ago that anybody began to be curious about language and to start examining it.

Ancient roots. The systematic study of language, linguistics, began independently in ancient India and Greece. Pāṇini, an Indian linguist around the 5th century BC, developed a sophisticated, rule-based approach to Sanskrit grammar, remarkably anticipating modern formal linguistics. In Europe, Greek scholars like Aristotle and Dionysius Thrax laid the foundation for grammatical description, categorizing words into "parts of speech," a system later adopted and adapted by Roman grammarians for Latin, notably Priscian.

Shifting focus. For centuries, European grammar was largely prescriptive, attempting to impose Latin structures onto other languages and dictating "correct" usage. However, the 17th-century Port-Royal Circle introduced a more universal and philosophical approach, recognizing that speakers make "infinite use of the finite resources" of language. The late 18th century saw the rise of historical linguistics, which revealed systematic resemblances among languages, leading to the discovery of language families like Indo-European, and temporarily overshadowing other linguistic inquiries.

Modern general linguistics. By the late 19th century, the non-historical study of language structure re-emerged, leading to what is now called general linguistics—the study of how languages are put together and how they work. This shift marked a move towards descriptivism, where linguists aim to record and describe language as it is actually used, rather than prescribing how it should be used. This scientific, empirical approach forms the bedrock of modern linguistic inquiry, seeking to understand the underlying systems of human communication.

2. Language as a Structured System: Saussure's Enduring Legacy

This novel approach quickly came to be called structuralism, and, since Saussure’s work, virtually all important work on languages has been structuralist in this sense.

Structuralist revolution. Ferdinand de Saussure, a Swiss linguist, revolutionized the field by proposing a structuralist approach to language. Before Saussure, linguists often viewed language atomistically, as a collection of isolated sounds or words. Saussure argued that language is an orderly system, or a "system of systems," where the meaning and function of linguistic units are defined by their relationships and oppositions within the larger structure, not by their inherent properties.

Phonemes and meaning. A key concept in structuralism is the phoneme, the smallest unit of sound that can distinguish meaning in a language. For example, in English, /d/ and /ð/ are distinct phonemes because "den" and "then" have different meanings. In contrast, in Spanish, [d] and [ð] are variations of a single phoneme, as their occurrence is predictable based on position and does not change meaning. This highlights that it's the structural relation of sounds that matters, not just their objective phonetic facts.

Synchronic vs. diachronic. Saussure also emphasized the distinction between synchronic and diachronic approaches. A synchronic study examines a language's structure at a specific point in time, focusing on its internal system. A diachronic study, conversely, analyzes how a language develops and changes over time. While historical linguistics focuses on diachronic change, Saussure's structuralism provided a framework for understanding the systematic nature of language at any given moment, influencing subsequent schools like the Prague Circle and American structuralism.

3. The Innate Human Language Faculty: A Biological Imperative

In fact, many people would argue that our unique possession of language is the most important characteristic that we have, the one that most decisively sets us apart from all other species.

Defining natural language. Linguists define "natural language" as any language that is, or once was, the mother tongue of a group of human beings. This includes all 6,500+ languages worldwide, regardless of their number of speakers, political status, or whether they have a written tradition. For linguists, all natural languages are equally valuable for understanding the universal properties of human communication, which collectively form what is called "language" or our "language faculty."

Unique design features. Human languages possess distinct "design features" absent in animal communication systems, as identified by Charles Hockett. These include:

• Vast vocabulary: Thousands of words and mechanisms for creating new ones.
• Morphological modification: Ways to change word meanings (e.g., tense, plural).
• Negation and questions: Ability to express "not" and ask inquiries.
• Abstraction: Concepts like "redness" or "absence."
• Displacement: Talking about things not present in time or space.
• Open-endedness: Producing and understanding novel utterances effortlessly.
• Stimulus-freedom: Ability to say anything, or nothing, in any circumstance.
  These abilities are universal among humans, from professors to Stone Age tribesmen, highlighting language as a peculiarly human trait.

Evidence from creoles. The innate human capacity for language is powerfully demonstrated by the emergence of pidgins and creoles. When speakers of different languages are forced to communicate, they develop a rudimentary "pidgin" with limited vocabulary and grammar. Crucially, children exposed to a pidgin as their primary language spontaneously transform it into a complex, fully grammatical "creole," creating a new natural language. This, along with the development of Nicaraguan Sign Language by deaf children, provides compelling evidence that humans are born with a biological "language urge" to construct and use language, a core tenet of Noam Chomsky's Universal Grammar.

4. Language is Dynamic: Constant Change and Variation

Language change is ceaseless and remorseless, and it causes languages to diverge from their earlier forms almost without limit.

Ever-evolving language. Languages are not static entities; they are constantly changing, day by day, generation by generation. This ceaseless evolution leads to significant divergence over time, making older forms of a language, like Old English, virtually unrecognizable to modern speakers. These changes encompass pronunciation, vocabulary, and grammatical forms, and are a natural, ongoing process in all living languages.

Prescriptivism vs. descriptivism. The constant evolution of language often clashes with "prescriptivism," the conservative attitude that seeks to maintain language as it was in a previous generation, often railing against new usages. Historically, such protests have proven futile, as changes like "My house is being painted" eventually become accepted as standard. Linguists, however, generally adopt a "descriptivist" stance, focusing on recording and describing language as it is actually used, rather than dictating how it should be.

Variation as the vehicle of change. The key to understanding language change lies in "variation." At any given time, older and newer forms of a linguistic feature coexist, with different speakers or contexts favoring one over the other. Over time, the newer form gradually becomes more frequent until the older one disappears. This variation is also evident across social groups (e.g., men vs. women, different professions) and contexts, demonstrating that even a single person speaks differently depending on the circumstances. Sociolinguistics studies these pervasive variations and their role in language evolution and social identity.

5. Meaning Beyond Words: The Power of Context and Cognition

The study of the way in which we extract communicative meanings from the context of utterances is now called pragmatics.

Semantics: Intrinsic meaning. Semantics is the study of meanings intrinsic to linguistic forms, independent of context. However, defining even simple words like "dog" rigorously proves surprisingly difficult, as meanings are often fuzzy and depend on connections to other words. This complexity led some early American structuralists to temporarily exclude semantics from linguistics, though it was later reintegrated.

Pragmatics: Contextual meaning. In contrast, pragmatics investigates how we derive communicative meanings from the context of utterances. This goes beyond the literal meaning of words. For example, "Susie's on antibiotics" in the context of finding a driver for a Christmas party implies "Susie can drive." This interpretation relies on shared world knowledge (parties involve drinking, antibiotics prevent drinking, non-drinkers can drive). Paul Grice's maxims, like the maxim of relevance and quantity, explain how listeners assume cooperation and infer unstated meanings.

Cognitive linguistics: Perception and metaphor. Cognitive linguistics offers another perspective, linking language structure and function to human perception and cognition. It explores how our understanding of the world shapes our language. For instance, the English metaphor of time as a stationary entity we move through ("future is in front") contrasts with the Ancient Greek view of time moving past us ("past is in front"). This approach highlights the central role of "cognitive metaphor" in shaping linguistic expression, suggesting that much of language is built upon metaphorical mappings from concrete experiences to abstract concepts.

6. Children Actively Construct Language Rules

Such observations show clearly that the child cannot be proceeding by memorization or imitation. Instead, it must be constructing rules.

Beyond imitation. Early theories, like B.F. Skinner's, suggested children acquire language through imitation and reinforcement. However, Noam Chomsky famously critiqued this view, and subsequent research has shown that children actively construct linguistic rules rather than merely imitating. They don't produce random errors; instead, their errors often reveal an underlying rule-governed system they are developing.

Rule-governed development. Children's acquisition of English past tenses illustrates this:

• Initially, they learn frequent irregular forms (e.g., "saw," "took").
• Later, they discover the regular "-ed" rule and overgeneralize it (e.g., "taked," "goed").
• Eventually, they learn the exceptions and use both regular and irregular forms correctly.
  Similarly, in acquiring negation, children progress through stages, from "No I want milk" to "I no want milk" and finally "I don't want milk," demonstrating a systematic construction of grammatical rules.

The "wug test" and innate faculty. The "wug test" provides compelling evidence for rule construction: children can correctly form the plural of a novel, nonsense word ("wug" becomes "wugs"), proving they have internalized a rule, not just memorized words. This active construction, coupled with the universal ability of all healthy children to acquire a first language (even in the absence of full linguistic input, as seen with creoles), strongly suggests an innate "biological language faculty." This faculty, a core concept in Chomsky's Universal Grammar, predisposes humans to acquire language, requiring only minimal environmental stimulation.

7. The Brain's Language Blueprint: Insights from Disordered Speech

Disordered language resulting from brain damage is called aphasia (or dysphasia), and several different types are known.

Brain-language connection. Our language ability is deeply intertwined with specific areas of the brain. Damage to these areas can lead to "aphasia," or disordered language. In the 1860s, Paul Broca identified "Broca's aphasia," characterized by slow, laborious speech with little grammar, linked to damage in Broca's area (left frontal lobe), confirming its role in grammatical structure and speech motor control.

Wernicke's area and comprehension. A decade later, Carl Wernicke identified "Wernicke's aphasia," where sufferers speak fluently but nonsensically, with impaired comprehension. This was linked to damage in Wernicke's area (left temporal lobe), suggesting its role in language comprehension and vocabulary access. These early discoveries laid the foundation for "neurolinguistics," the study of language functioning within the brain.

Specific deficits and genetic links. Modern neurolinguistics, using brain scanners, has confirmed and expanded these findings, revealing highly specific linguistic deficits. For example, some patients lose only words for fruits, or verbs but not nouns. "Specific Language Impairment (SLI)" is a genetic disorder where individuals struggle with grammatical words and rules, failing the "wug test" and suggesting a deficit in the "rule component" of language. Conversely, "Williams Syndrome" sufferers, despite severe mental retardation, acquire linguistic rules easily but struggle with word finding, pointing to a distinct "storage/look-up" component. These findings, as argued by psycholinguist Steven Pinker, suggest our language faculty comprises distinct rule-based and memory-based components, with genetic defects potentially targeting specific aspects.

8. Unraveling Language's Origins and Multifaceted Purposes

But that doesn’t mean we are much closer to answering the question of how, when or why language began.

A historical taboo. For many years, the origin of language was a taboo topic in linguistics, largely due to a lack of significant data on language structure, brain function, or human ancestry. Despite advances in these fields today, a consensus on how, when, or why language began remains elusive, with specialists from various disciplines offering conflicting speculations.

Conflicting theories of origin. Theories on language origin vary widely:

• Gradualist theory: Proposes language emerged slowly, in tiny increments, driven by natural selection (Pinker & Bloom). Critics find it hard to imagine what a "partial language" (e.g., nouns but no verbs) would look like, as such systems are not observed in nature, except for pidgins.
• Catastrophic theory: Suggests a sudden, "overnight" emergence from a crude "protolanguage" (like pidgins or early child speech) to full human language, due to a crucial brain connection (Derek Bickerton).
• Other speculations: Language grew out of gestures, or from vocal grooming.
  The available data, from archaeology to fossil skulls, points in different directions, preventing a unified theory.

Language's diverse purposes. It is unlikely that language evolved to serve a single purpose. Instead, it serves a wide array of functions, far beyond mere information transfer:

• Communication: Passing information, persuading, convincing.
• Social bonding: Maintaining relations, expressing individuality, displaying social status.
• Cognition: Organizing the world, constructing mental representations.
• Expression: Amusing, entertaining, expressing emotion.
  Language is deeply embedded in human existence, distinguishing us from other species, and its richness suggests it evolved to fulfill multiple, interconnected needs rather than a singular, accidental discovery of utility.
