Sociolinguistics: Variation, Pidgins and Creoles, Multilingualism and Language Policy

This chapter answers Section XH3.4 of XH3 Linguistics, "Sociolinguistics (Language and Society)", one of the six optional sections of the Humanities and Social Sciences (XH) paper, chosen at application. The heading names language variation (sociolects, dialects, dialect geography, pidgins and creoles, linguistic variables and communicative competence), bi- and multilingualism (code-switching and code-mixing), and language and policy (official language policy especially in India, endangerment measured by EGIDS, language loss, maintenance, documentation and revitalization, and minority and majority languages). The chapter treats language as a social object: how it varies across groups and situations, how contact produces new languages, how bilinguals manage several codes, and how states and communities try to protect or promote languages.

1. The space of variation: dialect, sociolect, register and standard

No one speaks a language in only one way. Variation is organised along two axes: by user and by use. Varieties tied to the speaker are dialects (regional varieties differing in pronunciation, vocabulary and grammar), sociolects (varieties of a social class or group), and idiolects (one individual's speech); an accent is pronunciation only, so it is narrower than a dialect. Varieties tied to the situation are registers (functional varieties, such as legal or sports-commentary language) and styles (degrees of formality). The standard is simply the dialect that has been codified and given official and educational backing; it is not linguistically superior to any other.

  • Jargon is the specialist vocabulary of a trade or field, and slang is informal, often in-group vocabulary that dates quickly; both are usually classed as variation by use (register and style) rather than regional dialect.
  • Style runs along a scale of formality from casual to careful speech, and a single speaker shifts style with the situation, the audience and the topic, without changing dialect.
ℹ️ Diglossia
Diglossia (Charles Ferguson, 1959) is a stable arrangement in which two varieties of a language divide the labour: a prestige High (H) variety for formal, written and public functions, and a Low (L) variety for home and everyday talk, each used in its own domains and rarely swapped. Classical versus colloquial Arabic, and literary versus spoken Tamil, are standard examples. Fishman later extended the idea to two separate languages in a community.

2. Variation in space: dialect geography

Dialect geography (dialectology) maps where features change across territory. The line on a map separating places that use one variant from places that use another is an isogloss; where many isoglosses run together they form a bundle that marks a perceived dialect boundary. Often, though, varieties shade into one another with no sharp break: a dialect continuum is a chain in which each village understands its neighbours, but the two ends are mutually unintelligible (as across the North Indian plains, or the continental West Germanic and Romance areas). Migration and contact carry variants into new regions, so the map is always a snapshot of change in progress.

This is why the language-versus-dialect question has no purely linguistic answer. Mutual intelligibility is a linguistic criterion, but it is regularly overridden by politics and identity: varieties that are mutually intelligible may be called separate languages (for political reasons), while varieties that are not intelligible to one another may be grouped under one 'language'. The point is captured in the saying, famously quoted by Max Weinreich, that 'a language is a dialect with an army and a navy'.

⚠️ Accent is not dialect
An accent is a difference of pronunciation alone. A dialect differs in pronunciation and also in words and grammar. Two people can share a dialect but have different accents; calling every pronunciation difference a 'dialect' overstates the distance between them.

3. Pidgins and creoles

When groups with no common language must communicate (typically in trade, plantation or port settings), a pidgin may arise: a reduced contact language with simplified grammar, a small vocabulary and no native speakers, used only for limited purposes. Its vocabulary comes mainly from the dominant lexifier (superstrate) language, while the grammar is shaped by the speakers' native substrate languages. A pidgin is nobody's mother tongue.

When a pidgin acquires a community of native speakers and expands into a full language able to do everything a language must, it becomes a creole (the process is creolization); Haitian Creole is a standard example; Tok Pisin began as a pidgin and is now also a first language for many speakers; and Nagamese in north-east India is widely described as an Assamese-based creole. Where a creole stays in contact with its lexifier, speakers spread along a creole continuum from the basilect (furthest from the standard) through the mesolect to the acrolect (closest to it); a drift of the whole community toward the lexifier is decreolization.

⚠️ The native-speaker line
The single clearest criterion separating a pidgin from a creole is native speakers: a pidgin has none, a creole has a community for whom it is a first language. Calling a creole a 'pidgin' because it looks simple, or because of how it began, misses that it is now a complete, nativized language.

4. The linguistic variable and communicative competence

Variationist sociolinguistics, founded by William Labov, studies the linguistic variable: a feature with two or more variants whose choice correlates with social factors (class, age, sex, ethnicity) and with style. Labov's New York department-store study of post-vocalic (r), and the (ing) variable (walking versus walkin'), showed that variants pattern by class and that speakers use more of the prestige variant as they pay more attention to speech. Useful concepts: overt prestige (the openly admired standard) versus covert prestige (the hidden value of a non-standard form within a group), hypercorrection (a lower-status group overshooting the prestige target in careful speech), the observer's paradox (we want to record how people speak when not observed), and apparent-time study (comparing age groups to infer change).

Communicative competence (Dell Hymes, 1972) is the knowledge a speaker needs beyond grammar: knowing what to say, to whom, when, where and how, so that speech is not only well-formed but appropriate. Hymes proposed it in answer to Chomsky's narrow competence/performance distinction, arguing that knowing a language includes knowing its social rules of use. His SPEAKING grid (setting, participants, ends, act sequence, key, instrumentalities, norms, genre) is a checklist for describing a speech event in the ethnography of communication.

📖 The department-store test
In his New York study, Labov simply asked staff in three department stores of different prestige a question whose answer was 'fourth floor', then recorded how often each pronounced the (r). Staff in the higher-prestige store used more of the prestige (r), and all three used more of it when asked to repeat the phrase carefully, tying the variable neatly to both social class and attention to speech.

5. Bilingualism, code-switching and code-mixing

Bilingualism can be individual (one person's command of two languages) or societal (two languages used in one community). Bilinguals range from balanced to dominant in one language. Lambert distinguished additive bilingualism, where a second language is gained at no cost to the first (often with prestige), from subtractive bilingualism, where the second language displaces the first (often in minority settings). Everyone has a mother tongue (first language) alongside other tongues learned later.

  • Code-switching is the alternation between languages or varieties within one conversation. Poplack's types are tag-switching (a tag or filler from the other language), inter-sentential (switching at a sentence boundary) and intra-sentential (switching within a single clause).
  • Code-mixing usually refers to intra-sentential blending of elements from two codes. Blom and Gumperz separated situational switching (driven by a change of setting or addressee) from metaphorical switching (used to signal an attitude or identity within the same setting).
  • Code-switching is governed by grammatical constraints (Myers-Scotton's Matrix Language Frame treats one language as the frame), and it is not the same as borrowing: a borrowed word is integrated into the other language, whereas a switch keeps the grammar of its own language.

6. Language policy, endangerment and revitalization

Language policy and planning has three classic arms: status planning (deciding a language's official roles), corpus planning (fixing its spelling, grammar and vocabulary) and acquisition planning (promoting who learns it, mainly through schooling). India is a working laboratory of such policy: its states were reorganized largely on linguistic lines (1956), the Constitution lists scheduled languages in its Eighth Schedule and makes Hindi (with English) an official language of the Union, and the three-language formula shapes schooling. A recurring exam point is that the Constitution names an official language of the Union, not a 'national' language.

A language is endangered when it is losing speakers, and the single most important warning sign is a break in intergenerational transmission (parents no longer passing it to children). Fishman's GIDS graded this, and the EGIDS (Expanded Graded Intergenerational Disruption Scale, Lewis and Simons), used by Ethnologue, places a language on a numbered scale in which a higher number means weaker vitality: level 6a is vigorous, 6b is threatened (some but not all of the child-bearing generation pass it on), 7 is shifting (the child-bearing generation uses it among themselves but does not transmit it to children), 8a is moribund (only the grandparent generation and older still use it), and the later stages run on through nearly extinct and dormant to extinct. When transmission stops entirely the language undergoes shift and then death (loss). Two responses differ in aim: documentation records a language (recordings, a grammar, a dictionary, an annotated corpus) as a lasting archive, while revitalization tries to get it spoken again (as with Hebrew's revival, or immersion 'language nests' for Maori). Maintenance keeps a healthy language from slipping, and minority versus majority status reflects power and prestige, not merely numbers.

⚠️ Documentation is not revitalization
Documentation preserves a record of a language for the archive and for scholarship; revitalization aims to restore living, everyday use by new speakers. A fully documented language can still die if no child learns it, and a revitalized one may be poorly documented. The exam often tests this contrast of purpose.

India's three-language formula, framed in national education policy, envisages a child learning the regional language, Hindi and English (in Hindi-speaking states, the third language was to be another modern Indian language, preferably a southern one). Alongside it, the reorganization of states on linguistic lines gave many large languages a home state, strengthening their status, while scattered minority and tribal languages depend instead on separate protections and on community-led maintenance and revitalization.

Key takeaways

  • Variation runs by user (dialect, sociolect, idiolect; an accent is pronunciation only) and by use (register, style). The standard is a codified, backed dialect, not a superior one. Diglossia (Ferguson) is a stable High/Low split of functions.
  • Dialect geography maps features with isoglosses and bundles; a dialect continuum shades gradually with intelligible neighbours but unintelligible ends. The language-versus-dialect line is social and political, not purely linguistic (army and navy).
  • A pidgin is a reduced contact language with no native speakers, lexifier vocabulary and substrate grammar; a creole is a nativized, expanded pidgin. A creole continuum runs basilect to acrolect, and drift toward the lexifier is decreolization.
  • Labov's linguistic variable has variants that correlate with class, age, sex and style; key ideas are overt versus covert prestige, hypercorrection, the observer's paradox and apparent time. Hymes's communicative competence adds appropriate use to grammatical knowledge.
  • Bilingualism is individual or societal, balanced or dominant, additive or subtractive (Lambert). Code-switching alternates languages (tag, inter- and intra-sentential; situational versus metaphorical) and differs from borrowing, which integrates a word into the other language.
  • Language planning is status, corpus and acquisition planning; India reorganized states on linguistic lines and makes Hindi (with English) an official, not national, language. Endangerment hinges on intergenerational transmission; EGIDS grades vitality; documentation records while revitalization restores living use.

Practice questions (17)

Attempt each one before opening the answer. Every explanation names the tempting wrong option as well as the right one, because that is where marks are lost.

  1. In sociolinguistics, which term names a language variety defined by the situation of use rather than by the speaker, for example the special language of legal documents or sports commentary?

    1. Register, a functional variety tied to a particular situation or activity of use
    2. Dialect, a regional variety tied to where a speaker comes from geographically
    3. Sociolect, a variety tied to the social class or group that a speaker belongs to
    4. Idiolect, the distinctive speech pattern characteristic of a single individual person
    Show answer

    Answer: A — Register, a functional variety tied to a particular situation or activity of use

    A variety defined by the situation of use is a register. Dialect, sociolect and idiolect are all varieties defined by the user (where they are from, their social group, or the individual), not by the activity, which is exactly the contrast the question draws.
  2. A community uses a prestigious High variety for sermons, writing and formal speeches, and a Low variety for home and the market, each kept to its own domains. Ferguson called this stable arrangement:

    1. Decreolization, where a whole speech community drifts toward its lexifier language
    2. Diglossia, a stable division of labour between a High and a Low variety by domain
    3. Hypercorrection, where speakers overshoot a prestige target in their careful speech
    4. Code-mixing, the intra-sentential blending of material drawn from two codes
    Show answer

    Answer: B — Diglossia, a stable division of labour between a High and a Low variety by domain

    A stable High/Low split by domain is diglossia, Ferguson's term. Decreolization is a creole drifting toward its lexifier; hypercorrection is overshooting a prestige norm; code-mixing is blending two codes within a sentence. Only diglossia describes two varieties with complementary functional domains.
  3. On a dialect map, the line drawn to separate the places that use one variant of a feature from the places that use another is called:

    1. A basilect, marking the variety that lies furthest from the recognised standard
    2. A matrix language, which is the language that supplies the main grammatical frame in an instance of code-switching
    3. An isogloss, a line separating areas that differ in the chosen linguistic feature
    4. A speech community, the group of people who share norms for using a language
    Show answer

    Answer: C — An isogloss, a line separating areas that differ in the chosen linguistic feature

    An isogloss is the map line dividing areas by a linguistic variant, and a bundle of isoglosses marks a dialect boundary. A basilect is a point on a creole continuum, a matrix language is a code-switching notion, and a speech community is a group of speakers, none of them a map line.
  4. Two neighbouring varieties are fully mutually intelligible, yet across a national border each is officially called a separate 'language'. Which statement best reflects how linguists understand the language-versus-dialect distinction here?

    1. The one with more speakers must be the language and the other must be its dialect
    2. Whichever variety has a writing system is the language and the spoken-only one is a dialect
    3. Mutual intelligibility by itself proves beyond any doubt that they are one and the same language, so the official labels must simply be an error
    4. The distinction is often social and political; political status can override the linguistic criterion of intelligibility
    Show answer

    Answer: D — The distinction is often social and political; political status can override the linguistic criterion of intelligibility

    Linguists hold that the language/dialect line is largely social and political: mutually intelligible varieties can count as separate languages for political reasons (the 'army and navy' point). Speaker numbers and the presence of writing are not the defining criteria, and calling the official labels a mere error ignores that the distinction is not purely linguistic in the first place.
  5. Which of the following statements about language varieties are correct?

    1. An accent is a difference of pronunciation alone, narrower than a dialect
    2. A standard variety is a codified dialect, not one that is linguistically superior to others
    3. In a dialect continuum, adjacent varieties are intelligible but the two far ends may not be
    4. A dialect differs from other varieties only in pronunciation, never in words or grammar
    Show answer

    Answer: A — An accent is a difference of pronunciation alone, narrower than a dialect; B — A standard variety is a codified dialect, not one that is linguistically superior to others; C — In a dialect continuum, adjacent varieties are intelligible but the two far ends may not be

    An accent is pronunciation only; the standard is a codified variety with official backing, not an inherently better one; and a continuum has intelligible neighbours with unintelligible ends. The last claim is false: a dialect differs in pronunciation and also in vocabulary and grammar, which is exactly what distinguishes it from a mere accent.
  6. Which feature is the defining characteristic of a pidgin, as opposed to a creole?

    1. It has no native speakers and is used only for limited purposes
    2. It is always written in the script of its lexifier language
    3. It takes its grammar entirely from a single prestige language
    4. It is spoken natively by the children growing up in a settled, established community
    Show answer

    Answer: A — It has no native speakers and is used only for limited purposes

    A pidgin has no native speakers and serves limited, usually practical, functions; this is the sharpest line between it and a creole. Pidgins need not be written at all; their grammar is shaped by the substrate languages, not taken wholesale from one language; and being spoken natively by children describes a creole, not a pidgin.
  7. A contact language that began as a simplified trade jargon is now the first language of a whole community of children, with a full and expanded grammar. This language is best described as:

    1. A pidgin, because its original source lies in an earlier simplified trade jargon
    2. A creole, because a pidgin has become the native language of a community
    3. A register, because it is used for the special purpose of trade
    4. An isogloss, because it marks a boundary between two trading regions
    Show answer

    Answer: B — A creole, because a pidgin has become the native language of a community

    A pidgin that gains native speakers and expands into a full language is a creole; that is precisely creolization. Its trade origin does not keep it a pidgin now that it has native speakers. A register is a situational variety, and an isogloss is a line on a map, so neither fits a nativized contact language.
  8. In the formation of a pidgin, which description of the lexifier (superstrate) and the substrate is correct?

    1. The lexifier supplies most of the grammar, while the substrate supplies most of the vocabulary
    2. Both the vocabulary and the grammar come equally from the substrate languages only
    3. The lexifier supplies most of the vocabulary, while the substrate languages shape the grammar
    4. Both the vocabulary and the grammar come equally from the lexifier language only
    Show answer

    Answer: C — The lexifier supplies most of the vocabulary, while the substrate languages shape the grammar

    By definition the lexifier (usually the socially dominant language) provides most of the words, while the speakers' own substrate languages influence the grammar and phonology. Accounts that reverse these roles, or attribute everything to one side, misstate the standard account of how a pidgin is built.
  9. In Labovian variationist sociolinguistics, a 'linguistic variable' is best defined as:

    1. A grammatical rule that is held to apply without any exception to every single word in the language
    2. A word that has been borrowed and fully integrated from a prestige language
    3. A single fixed pronunciation shared by every speaker of the standard variety
    4. A feature with two or more variants whose use correlates with social and stylistic factors
    Show answer

    Answer: D — A feature with two or more variants whose use correlates with social and stylistic factors

    A linguistic variable is a feature with alternating variants (such as -ing versus -in') whose distribution correlates with class, age, sex and style. An exceptionless rule is a sound law; an integrated loanword is borrowing; and a single fixed pronunciation is the opposite of a variable, which by definition varies.
  10. Dell Hymes introduced 'communicative competence' mainly to argue that knowing a language involves:

    1. Knowing not only its grammar but also how to use it appropriately for the context
    2. Mastering only the formal rules that generate all and only the grammatical sentences of it
    3. Memorising the complete vocabulary and spelling of the standard written form
    4. Reconstructing the proto-language from which the modern language descends
    Show answer

    Answer: A — Knowing not only its grammar but also how to use it appropriately for the context

    Communicative competence adds knowledge of appropriate use (to whom, when, where, how) to grammatical knowledge, a response to Chomsky's purely grammatical competence. Grammatical rules alone are what Hymes found too narrow; vocabulary memorisation and proto-language reconstruction are unrelated to his concept.
  11. Which of the following statements about Labov's variationist findings and methods are correct?

    1. Speakers tend to use more of the overt-prestige variant as they pay more attention to their speech
    2. Hypercorrection can lead a lower-status group to exceed higher-status speakers on a prestige variant in careful styles
    3. The observer's paradox is the difficulty of recording how people speak when they are not being observed
    4. A non-standard form can never carry prestige, because prestige belongs only to standard forms
    Show answer

    Answer: A — Speakers tend to use more of the overt-prestige variant as they pay more attention to their speech; B — Hypercorrection can lead a lower-status group to exceed higher-status speakers on a prestige variant in careful styles; C — The observer's paradox is the difficulty of recording how people speak when they are not being observed

    The first three are standard results of variationist work: prestige variants rise with attention to speech; lower-middle-class hypercorrection can overshoot higher-status usage in formal styles; and the observer's paradox names the recording problem. The last claim is false: covert prestige shows that a non-standard form can be valued within a group even without open approval, which is why such forms persist.
  12. A bilingual speaker inserts an English noun phrase into the middle of a Hindi clause, keeping the clause otherwise in Hindi. This within-clause alternation is best described as:

    1. Inter-sentential code-switching, because the switch happens between two full sentences
    2. Intra-sentential code-switching (code-mixing), because the switch happens within one clause
    3. Decreolization, because the speaker is moving toward a more prestigious lexifier
    4. Diglossia, because the two languages are assigned to separate functional domains
    Show answer

    Answer: B — Intra-sentential code-switching (code-mixing), because the switch happens within one clause

    A switch inside a single clause is intra-sentential code-switching, often called code-mixing. Inter-sentential switching occurs at sentence boundaries, not within a clause. Decreolization is a creole drifting toward its lexifier, and diglossia is a domain-based split of two varieties, neither of which is a single within-clause switch.
  13. Which of the following statements about bilingualism and code-switching are correct?

    1. Additive bilingualism adds a second language without loss of the first, unlike subtractive bilingualism
    2. Code-switching is random and follows no grammatical constraints whatsoever
    3. Borrowing integrates a word into the recipient language, whereas a switch keeps its own grammar
    4. Societal bilingualism refers to two languages being used within a single community
    Show answer

    Answer: A — Additive bilingualism adds a second language without loss of the first, unlike subtractive bilingualism; C — Borrowing integrates a word into the recipient language, whereas a switch keeps its own grammar; D — Societal bilingualism refers to two languages being used within a single community

    Additive bilingualism keeps the first language while adding a second; borrowing integrates a word whereas switching preserves each language's grammar; and societal bilingualism is community-level. The claim that code-switching is random is false: it is rule-governed, as the Matrix Language Frame and other constraint models show.
  14. Blom and Gumperz distinguished two kinds of switching. A speaker who switches languages purely to signal solidarity or a shift in attitude, without any change in setting or addressee, is performing:

    1. Situational switching, because it is triggered by a change in the external situation
    2. Decreolization, because the speaker is abandoning a basilect for an acrolect
    3. Metaphorical switching, because it is used to convey social meaning within one setting
    4. Corpus planning, because the speaker is standardising the grammar of the two codes
    Show answer

    Answer: C — Metaphorical switching, because it is used to convey social meaning within one setting

    Switching to signal attitude or solidarity with no change of setting is metaphorical switching; situational switching, by contrast, is driven by a change in setting or addressee. Decreolization is a creole phenomenon and corpus planning is a policy activity, so neither describes this discourse move.
  15. On the EGIDS and in Fishman's framework, which single factor is treated as the most decisive warning sign that a language is becoming endangered?

    1. The absence of a standardised spelling system or a long written literary tradition
    2. The borrowing of a large number of words from a neighbouring majority language
    3. The existence of several regional dialects that differ noticeably within the language
    4. A break in intergenerational transmission, where children no longer acquire it at home
    Show answer

    Answer: D — A break in intergenerational transmission, where children no longer acquire it at home

    Fishman's work and the EGIDS both make intergenerational transmission the pivotal indicator: a language survives if children learn it at home. Lacking a standard spelling or written tradition, borrowing words, or having internal dialects are not themselves signs of endangerment, since many vigorous languages show all three.
  16. Which of the following statements about language policy, endangerment and documentation are correct?

    1. Status planning concerns the official roles of a language, while corpus planning fixes its forms such as spelling and grammar
    2. Documentation aims to record a language, whereas revitalization aims to restore its living everyday use
    3. Minority and majority status is purely a matter of speaker numbers, with power and prestige playing no part
    4. A language can be thoroughly documented and yet still die if no new generation learns to speak it
    Show answer

    Answer: A — Status planning concerns the official roles of a language, while corpus planning fixes its forms such as spelling and grammar; B — Documentation aims to record a language, whereas revitalization aims to restore its living everyday use; D — A language can be thoroughly documented and yet still die if no new generation learns to speak it

    Status and corpus planning are correctly distinguished; documentation and revitalization differ in aim; and documentation alone cannot keep a language alive without new speakers. The minority/majority claim is false: these statuses reflect power and prestige, not numbers alone, so a numerically small group can be socially dominant.
  17. In an EGIDS-style grading, the parent (child-bearing) generation speaks a language among themselves, but that generation no longer passes it on to its children. Which level fits this description?

    1. Level 6a (vigorous), because all generations use it and children still acquire it at home
    2. Level 6b (threatened), because some but not all of the child-bearing generation still transmit it
    3. Level 7 (shifting), because the parent generation uses it but does not transmit it to children
    4. Level 8a (moribund), because only the grandparent generation and older still use it
    Show answer

    Answer: C — Level 7 (shifting), because the parent generation uses it but does not transmit it to children

    Parents who use the language among themselves but stop transmitting it to their children is the defining mark of level 7, shifting. Level 6a means children still acquire it; 6b means some of the child-bearing generation still transmit it, whereas here none do; and 8a means the parent generation no longer uses it at all, so only the grandparent generation and older remain, which contradicts the parents' continuing use.
