What term describes the communicative purpose or use of an utterance, which may differ from its form?

• A. Topic
• B. Function
• C. Notion
• D. NLP

Answer: (B)

Function describes the communicative purpose or use of an utterance, which may differ from its form. The form is how the sentence is constructed (a question, a statement, a command), while the function is what the speaker intends to achieve—informing, requesting, directing, etc. For example, “Could you pass the salt?” is shaped as a question, but its function is to request. The other terms don’t capture this idea: topic refers to what the utterance is about, not its purpose; notion isn’t the standard term here; NLP is a field, not the linguistic function of a specific utterance.
