What term describes the interactive, social, and behavioral aspects of language use?

The term that describes the interactive, social, and behavioral aspects of language use is pragmatics. Pragmatics focuses on how context influences the interpretation of meaning in conversation and interaction. This includes understanding the nuances of communication, such as tone, body language, and the social norms that dictate appropriate communication in various settings. It examines how people use language in real situations to achieve specific goals, whether that be to persuade, inform, question, or express emotions.

The other options represent different aspects of language: phonemes refer to the smallest units of sound in a language, morphemes are the smallest units of meaning, and extended text refers to longer pieces of written or spoken communication, but none of these incorporate the social and interactive elements that are central to pragmatics.
