Linguistics Glossary

A bound morpheme attached to a root or stem to create a new word or modify grammatical meaning, including prefixes, suffixes, infixes, and circumfixes.

A phonetic variant of a phoneme that occurs in a specific linguistic environment and does not change the meaning of a word.

The practice of alternating between two or more languages, dialects, or registers within a single conversation or utterance.

A word in one language that shares a common etymological origin with a word in another language, providing evidence of historical relationship between the languages.

A distinction introduced by Noam Chomsky: 'competence' is a speaker's unconscious knowledge of the rules of their language, while 'performance' is the actual use of language in real situations, which may include errors.

A stable, fully developed language that evolved from a pidgin and is acquired as a native language by a community of speakers.

The use of words or expressions whose reference depends on the context of the utterance, such as 'I,' 'here,' 'now,' and 'this.'

A morphological process that creates a new word, often with a different part of speech, by adding an affix to an existing word (e.g., 'happy' to 'happiness').

A regional or social variety of a language distinguished by particular features of pronunciation, grammar, and vocabulary.

A theory of grammar, associated with Chomsky, that models language as a finite set of rules capable of generating all and only the grammatical sentences of a language.

A meaning that a speaker conveys indirectly, which is inferred by the hearer based on context and conversational norms rather than stated explicitly.

A morphological process that modifies a word to express grammatical features such as tense, number, case, or person without changing the word's core meaning or part of speech.

A geographic boundary line on a dialect map that separates areas differing in a particular linguistic feature, such as pronunciation, vocabulary, or grammar.

A distinction introduced by Ferdinand de Saussure: 'langue' is the abstract, shared system of a language, while 'parole' is the individual, concrete use of language in actual speech.

The total stock of words and word-forming elements (morphemes) in a language; also refers to a speaker's mental dictionary of words and their properties.

The systematic classification and comparison of languages based on structural features such as word order, morphological type, and phonological inventory to identify cross-linguistic patterns.

The smallest unit of language that carries meaning, including roots, prefixes, suffixes, and other affixes.

The smallest contrastive unit of sound in a language that can distinguish one word from another (e.g., /p/ and /b/ in 'pat' and 'bat').

The branch of phonology that studies the permissible combinations and sequences of sounds in a given language.

A simplified language that develops as a contact language between groups with no common tongue, typically with reduced vocabulary and grammar.

The study of how context, speaker intention, and conversational norms contribute to meaning beyond literal semantic content.

A hypothetically reconstructed ancestral language from which a group of related languages is believed to have descended.

The branch of linguistics that studies the meaning of words, phrases, and sentences, including how meanings compose and relate to one another.

An utterance considered as an action, such as a request, promise, apology, or declaration. Speech act theory, developed by Austin and Searle, distinguishes locutionary, illocutionary, and perlocutionary acts.

The set of rules and principles governing how words combine to form grammatical sentences in a language.
