Generative principle

In foreign language teaching, the generative principle reflects the human capacity to generate an infinite number of phrases and sentences from a finite grammatical or linguistic competence. This capacity was captured in Wilhelm von Humboldt's famous phrase that language makes "infinite use of finite means". It is the theoretical basis for pattern drills and substitution tables - an essential component of the audio-lingual method - and may be considered as the necessary counterpart to the communicative principle, i.e. teaching communication through communicating (communicative language teaching; communicative competence).
