Pragmatics is a branch of linguistics that studies how context influences the interpretation of meaning in communication. It focuses on how people understand language in real-life situations, considering factors like tone, body language, and social norms. This helps explain why the same words can have different meanings depending on the circumstances. In pragmatics, concepts such as speech acts, implicature, and deixis are important. Speech acts refer to actions performed through speaking, like making requests or promises. Implicature involves implied meanings that go beyond the literal words used, while deixis relates to words that depend on context, such as here, there, you, and I.
