This document discusses several key concepts in semantics: - A reference is an object or entity in the world that a word refers to, while a referent is the actual word or expression used. One problem with references and referents is ambiguity. - Denotation is the literal or dictionary meaning of a word, while connotation involves cultural and emotional associations. - Context is crucial for determining meaning, as the same linguistic expressions can take on different meanings depending on how and when they are used. Pragmatics studies how context influences interpretation. - Semantics and pragmatics have a close relationship, as part of a word or phrase's meaning relies on the surrounding context.
