What is an 'exponent' in the functional-notional approach?

In the functional-notional approach, an 'exponent' refers specifically to a statement that is appropriate to a particular function, situation, and topic. This approach focuses on how language is used in real-life contexts, emphasizing the functions of language—such as requesting, offering, or apologizing—and the communicative situations in which these functions occur. The exponent embodies the actual language expression that serves to fulfill that communicative purpose within a context.

This understanding is important because it demonstrates the practical application of language in social interactions, rather than focusing solely on grammatical forms or vocabulary in isolation. By linking language use to functions and contexts, learners can develop a more nuanced awareness of how to communicate effectively in various scenarios.
