Linguistics (wiki)

• parts-of-speech-are-not-universal — the categories are language-particular descriptive conveniences

• language-is-for-thought — language evolved as an instrument of thought; communication is secondary (Chomsky)

Pragmatics (reclassified from the marketing communication map, 2026-08-05):

• grices-maxims — the cooperative principle and its four maxims
• speech-act-theory — utterances as acts (Austin, Searle)
• relevance-theory — comprehension as effect/effort optimization (Sperber & Wilson; the formula-shaped mirror stays at sperber-wilson-relevance)
