Pragmatics plays a vital role in a teacher's speech, turning simple words into effective communication that fosters a positive learning environment. Pragmatics is a discipline that investigates language use in its social and cultural context. In particular, pragmatics studies how language is interpreted by users beyond the literal meaning of the actual words used. Think of it like this: context is the setting, and pragmatics is the actor's performance within that setting. You use context clues to understand the setting, but pragmatics helps you interpret the actor's actions and emotions within that setting.
