Step by Step
1
Dell Hymes' response to Chomsky
Anthropologist Dell Hymes coined "communicative competence" in the 1960s as a direct response to Noam Chomsky's "linguistic competence" — Chomsky's term for the abstract, internalized knowledge of a language's grammar that lets a speaker produce and recognize well-formed sentences.
2
Grammatical vs. socially appropriate
Hymes pointed out that a sentence can be perfectly grammatical and still be a total communicative failure — a fluent speaker also has to know when it's appropriate to speak, what topics are acceptable in a given setting, and which register or tone fits the situation.
3
The four components of communicative competence
Later scholars (notably Canale and Swain) broke communicative competence into four parts: grammatical competence (vocabulary and grammar rules), sociolinguistic competence (using language appropriately for the social context), discourse competence (connecting sentences into a coherent, meaningful whole), and strategic competence (repair strategies for when communication breaks down, like rephrasing or asking for clarification).
4
Speaking is a cultural skill, not just a linguistic one
Because appropriateness varies by culture, communicative competence is inherently a cultural competence as much as a linguistic one — a perfectly grammatical sentence translated word-for-word into another language can still violate that culture's norms for who may say what to whom.
5
Ethnography of speaking
Hymes also developed the "ethnography of speaking" (or ethnography of communication) as a research method — studying speech events in their full cultural context (who speaks, to whom, in what setting, for what purpose) rather than analyzing language in the abstract, isolated from its social use.
Applied Walkthrough
1
A non-native English speaker has memorized flawless grammar and a large vocabulary — grammatically, every sentence they produce is correct.
2
But in a business meeting, they address a senior executive the exact same way they'd address a close friend, using overly casual phrasing and interrupting freely.
3
By Chomsky's standard of linguistic competence, nothing is wrong — every sentence is grammatical. By Hymes' standard of communicative competence, something has clearly gone wrong.
4
This gap is exactly what communicative competence captures: knowing the grammar is necessary but not sufficient for actually communicating successfully within a culture's norms.
Exam Application
Exams commonly test whether you can define communicative competence in contrast to Chomsky's linguistic competence, name the four Canale-and-Swain components, and explain why Hymes considered speaking a cultural as well as linguistic skill.
⚠ Common Trap
Don't confuse communicative competence with simple fluency or vocabulary size. A large vocabulary is part of grammatical competence only — a speaker can have an enormous vocabulary and still lack communicative competence if they don't know when, to whom, or how it's appropriate to use it.

2. What's the key difference between linguistic competence and communicative competence?
Linguistic competence is knowledge of grammar rules; communicative competence adds knowing what's socially appropriate to say, to whom, and when.

4. What is the "ethnography of speaking"?
Hymes' research method of studying speech events in their full cultural context — who speaks, to whom, where, and why — rather than analyzing language in isolation.

5. Can a perfectly grammatical sentence still be a communicative failure? Why?
Yes — if it violates the social or cultural norms of who may say what to whom in that context, it fails communicatively even though it's grammatically correct.
