Descriptive vs Prescriptive Grammar and the Abs Camouflage Construction (ACC)

Overview

• Recap of prior ideas: language misconceptions include the belief that more advanced societies with better technology have superior or more sophisticated languages.
• Evidence from history and cross-cultural study: experiments can be impossible to run, but natural experiments (an accident of history) allow comparison across groups with different technologies or contact histories.
• Papua New Guinea example: Western contact in the 1930s; technology was stone-age with some weaving and crop cultivation; linguists found the grammars of their languages to be as complex and sophisticated as any other language.
• Big takeaway: no clear correlation between material culture/technology and linguistic sophistication; supports the view that language is a uniform aspect of human biology, not merely a cultural artifact.
• Today’s focus: a linguist’s perspective on language, specifically the misconception that careful/formal speech or writing is always more sophisticated than casual speech; and the core question in linguistics: what does someone know when they know a language? What mental knowledge enables them to formulate and decode meaningful expressions?
• Course aim: build a model of speakers’ knowledge by formalizing rules of grammar; distinction between prescriptive and descriptive rules introduced to clarify what we mean by a "rule" in linguistics.

Key Concepts and Definitions

• Rule (in linguistics) can be two things:
  • Prescriptive rule: a rule imposed by some authority about how people should use language; a prescription.
  • Descriptive rule: a description of observed regularities in how language is actually used; not a judgment about right or wrong.
• Prescriptive rules (examples and rationale):
  • Teachers or media often discuss prescriptive grammar. Examples include avoiding ending sentences with prepositions or avoiding double negation.
  • Endings of sentences with prepositions: traditional advice says do not end a sentence with a preposition (eg, instead of I met the person I sent the letter to, use I met the person to whom I sent the letter).
  • Double negation: some regard it as illogical or inappropriate (eg, they don’t know nothing).
  • Justifications are often based on conventions, standardization, Latin models, or appeals to common sense rather than empirical usage.
• Descriptive rules (examples and rationale):
  • Describe how language is actually used by speakers.
  • English word order: typically, the object follows the verb (eg, I like ice cream; I ice cream like sounds wrong in standard usage).
  • Descriptive rules explain why certain forms are regular or frequent in actual speech, without prescribing what should be used.
  • Descriptive grammar tends to be conservative in the sense of describing what is rather than enforcing how it should be.
• The ambiguity of the term "rule":
  • Rules can be prescriptive (normative) or descriptive (generalizations about usage).
  • In science, laws are generalizations about regularities in the world; in everyday language, laws can function prescriptively or descriptively depending on usage.
• The linguist’s stance: study language descriptively, faithfully observing how people actually use language; no language is inherently superior in grammar or logic.
• Native speakers and grammaticality:
  • Native speakers: people who learned a language early in life and continue to use it.
  • Grammaticality: a sentence expresses a natural, well-formed structure according to the descriptive rules used by native speakers.
  • A star (*) marks ungrammatical sentences in the descriptive framework; it’s a descriptive observation, not a moral judgment about a language or its speakers.
• Acquisition and knowledge: grammatical knowledge is largely acquired, not explicitly taught; descriptive rules emerge from the development of the language faculty, which will be a focus of the course.

Prescriptive Rules: Why They Are Problematic for Descriptive Study

• Prescriptive rules are about authority and standardization, not about describing how people actually speak.
• They often aim to enforce a variety of language (especially written, “educated” forms) and can reflect power dynamics and social conventions.
• Examples highlighted:
  • Endings of sentences with prepositions: a prescriptive stance favors avoiding ending sentences with prepositions, but actual usage across dialects frequently ends with prepositions (eg, I met the person I sent the letter to).
  • Latin influence claims: historically, Dryden and others argued that Latin grammar should guide English; this is a prescriptive rationale grounded in cultural prestige rather than empirical evidence about English usage.
  • Latin-based concerns about sentence-final prepositions: the claim that Latin has no sentence-ending prepositions influenced debates about English style; this is an insufficient basis for normative rules about English.
  • Double negation: suggesting that forms like they don’t know nothing are illogical; in many languages and dialects, double negation functions as a negation emphasis and is accepted in actual use.
• Why this matters: enforcing prescriptive rules can obscure the reality of how language is used and can mischaracterize nonstandard varieties as inferior.

Descriptive Rules: How Linguists Understand Language Knowledge

• Descriptive approach describes regularities in actual speech across communities and contexts.
• Examples:
  • Object typically follows the verb in English: I like ice cream is standard; I ice cream like would be unusual in most dialects.
  • Descriptive rules capture cross-dialect variation (eg, some English varieties may allow forms that others disallow).
• Language learning and variation:
  • Descriptive rules are learned naturally through language acquisition; prescriptive rules are not the primary vehicle for teaching language knowledge.
  • In education, what students learn in school tends to be prescriptive rules; descriptive rules arise from natural language use rather than explicit instruction.
• Descriptive grammar is about faithful reporting of usage; prescriptive rules often do not reflect actual usage and can misrepresent linguistic competence.

Languages, Grammar, and Cross-Linguistic Variation

• Variation across languages and dialects is natural; different languages have different grammars, word orders, and rules.
• Latin vs English distinction: Latin does not align with English in some structural respects (eg, presence or absence of sentence-final prepositions).
• Variation within a language: some English dialects may apply or drop certain constructions (eg, duplicated DP in Italian for emphasis or other functions); there is no universal standard that all varieties conform to.
• The value of studying variation: understanding how and why varieties differ sheds light on universal grammar and the nature of language as a cognitive system, not merely a social artifact.

Abs Camouflage Construction (ACC): A Case Study in Descriptive Analysis

• ACC stands for abs camouflage construction; an example in English where the word my ass is used to refer to the speaker in a vulgar phrase like my ass might get fired.
• Purpose of studying ACC:
  • It provides a concrete case to examine how grammar handles nonstandard or colloquial forms.
  • It shows how a descriptive analysis can reveal patterns of agreement and reference that deviate from prescriptive norms.
• Key observations about ACC and agreement:
  • Subject-verb agreement in ACC can violate typical expectations: the sentence my ass might get fired does not force the main verb to agree with a first-person subject in the same way as if the subject were my cat or other third-person NP.
  • For example, with a standard third-person singular subject, one would expect a verb form like walks; with ACC, the question arises whether the agreement should align with the referent in first person or third person.
  • In practice, speakers overwhelmingly accept forms like my ass might get fired (regular non-3rd-person verb with is/are not required here), while forms like my ass am in trouble are judged ungrammatical by native speakers.
• Anaphora and reference: anaphoric pronouns typically refer back to a prior noun phrase and must agree in person, number, and gender with that antecedent. However, ACC reveals that the morphology of the verb may align with a different person than the referent of the noun phrase, illustrating a more complex interaction between pronoun reference, agreement, and discourse context.
• The role of the speaker in ACC and anaphora:
  • In a discourse where the ACC item refers to the speaker, the usual expectation would be first-person agreement, yet the verb often behaves as if the referent were third person in some contexts.
  • This observation challenges naïve assumptions about how agreement should track speaker identity and demonstrates the importance of descriptive analysis for understanding real language use.
• The takeaway from ACC:
  • The existence of ACC shows that language behavior can be rule-governed in ways that do not fit simple prescriptive norms; descriptive grammar must account for such patterns.
  • It also illustrates how minor, nonstandard forms can still obey systematic rules and be intelligible to native speakers.

Agreement, Anaphora, and What Speakers Know

• Subject-verb agreement:
  • Normally, the main verb forms to agree with the subject in person, number, and, in some languages, gender (eg, English: I walk vs he walks).
  • ACC data show exceptions and complexities in agreement patterns that help linguists refine theories of agreement and the architecture of the mental grammar.
• Anaphora:
  • Anaphoric pronouns refer back to a previous noun phrase and must align with the antecedent's person, number, and gender.
  • In the ACC discussion, the referent for my ass appears to be first person (the speaker), yet the agreement pattern on the verb can exhibit third-person morphology in certain contexts, revealing nontrivial interactions between referential and verbal agreement mechanisms.
• Descriptive generalizations relevant to ACC:
  • x is an element that shows third-person agreement with the verb when the referent of x is the subject of what is being discussed, but anaphoric pronouns may disagree with the expected person in some discourse contexts.
  • This motivates a cross-cutting generalization: the descriptive account should specify how anaphora interacts with local agreement constraints across constructions like ACC.
• Implications for learning and analysis:
  • These patterns are learned implicitly through exposure to language, not through explicit teaching of prescriptive rules.
  • They illustrate how native speakers have rich, rule-governed knowledge of their language even for constructions they would judge as vulgar or nonstandard.

Language Learning, Native Speakers, and Grammaticality

• Native speakers and grammaticality:
  • Grammaticality is defined relative to the descriptive rules that native speakers implicitly follow.
  • The star notation marks sentences that native speakers would deem ungrammatical; it does not imply moral judgments about speakers or their language.
• Acquisition and descriptive grammar:
  • Grammatical knowledge is largely acquired through exposure and use, not through explicit instruction in formal rules.
  • The course emphasizes descriptive grammar to uncover the mental grammar that speakers possess.
• The broader methodological point:
  • If researchers ignore nonstandard forms (like ACC) when constructing theories, they miss important data about the full range of human language performance.
  • Descriptive grammars aim to predict which sequences native speakers judge as grammatical or ungrammatical, across dialects and contexts.

Language Variation and Theoretical Implications

• Variation is inherent in languages:
  • Different languages have different grammars, but each grammar is internally coherent and rule-governed.
  • Differences between languages (eg, English vs Latin) illustrate how grammatical systems can diverge, but this does not imply one system is inherently superior.
• The role of standardization:
  • Standardization can aid broad communication in diverse communities, especially in formal domains like academia and law.
  • However, selecting a standard does not imply that other varieties are inferior; prescriptive norms reflect social conventions and power dynamics, not universal grammar.
• Ethical and practical implications:
  • Prescriptive biases can stigmatize dialects and nonstandard forms, reinforcing social hierarchies.
  • A descriptive approach recognizes linguistic diversity and emphasizes understanding language as a cognitive faculty rather than as a set of rules to police.
• What to expect in Unit 2 and beyond:
  • A deeper dive into grammar variation across languages and dialects, including how different grammars evolve and coexist.
  • Exploration of how different communities negotiate standardization versus variation in real-world communication.

Terminology and Key Takeaways

• Native speaker: someone who learned a language early in life and continues to use it.
• Grammaticality: whether a sentence aligns with the descriptive rules used by native speakers.
• Descriptive grammar: a faithful account of how people actually use language, including all dialectal and colloquial forms.
• Prescriptive grammar: rules that prescribe how people should use language, often tied to authority and standard forms.
• ACC (abs camouflage construction): a colloquial construction like my ass might get fired used to study agreement and reference patterns; demonstrates nonstandard but rule-governed language.
• Anaphora: the use of pronouns to refer back to a prior noun phrase, with agreement and reference constraints.
• Subject-verb agreement: the morphological changes in the verb to reflect features of the subject.
• Language variation: differences within and across languages, including dialectal and cross-language variation, that are natural and informative for linguistic theory.

Connections to Previous Lectures and Real-World Relevance

• Revisited ideas from earlier lectures about language misconceptions and the relationship between language and technology/social complexity.
• Emphasis on language as a biological/ cognitive faculty rather than a culture-bound artifact.
• Real-world relevance:
  • Understanding prescriptive norms helps explain why people police language and how social power shapes language use.
  • Descriptive grammar informs education, computational language processing, and cross-cultural communication by reflecting actual language use.
  • Awareness of variation supports inclusive attitudes toward different dialects, registers, and languages.

Guidance for Studying

• Distinguish prescriptive vs descriptive rules in examples you encounter.
• Practice identifying when a statement describes usage (descriptive) versus when it prescribes a usage (prescriptive).
• When analyzing constructions like ACC, focus on underlying patterns of agreement, reference, and grammaticality from a descriptive standpoint rather than judging them by prescriptive norms.
• Be prepared to discuss why prescriptive rules persist despite evidence that they do not align with actual language use, and what social factors contribute to their persistence.

Note on the Next Steps

• The course will cover grammar variation in more depth (Unit 2) and explore how different grammars operate across languages and communities.
• Expect further case studies illustrating how descriptive analysis reveals the complexity and regularities of human language, reinforcing the view that no language is inherently superior in its grammar.
