noun
linguistic performance
Technical term in linguistics, referring to the actual use of language in concrete situations, as opposed to competence.
チョムスキーは言語能力と言語運用を区別した。
Chomsky distinguished between linguistic competence and linguistic performance.
言語能力 refers to the underlying knowledge of a language (competence), while 言語運用 is the actual use of that knowledge in real situations (performance).
Compound of 言語 (language) and 運用 (operation, application). The term is a direct translation of the English 'linguistic performance' used in generative grammar.
