Meaning (philosophy)

Meaning is the sense or significance of something, such as an expression, representation, or event. It concerns what an entity conveys, stands for, refers to, or makes intelligible. Meaning is often understood as a relational concept that connects an entity to something else, such as the connection between the word dog and a four-legged mammal.

Philosophical inquiry usually centers on linguistic meaning, studying how words, sentences, and utterances acquire content and convey information. It examines how expressions describe the world and evoke emotions while distinguishing between speaker meaning and conventional meaning, and between literal and figurative meaning. Central debates address the contrast between sense and reference; the roles of vagueness, ambiguity, and context-dependence; and how the meaning of a complex expression depends on the meanings of its parts. Philosophers also discuss non-linguistic meaning associated with gestures, pictures, actions, and natural signs, such as footprints. Another topic concerns the meaning of life, asking whether human life or existence as a whole has a higher purpose.

Theories of meaning seek to identify its nature, sources, and functions, typically focusing on linguistic meaning. Reference-based theories hold that the meaning of an expression is what it stands for or the entity it denotes.
