Etymology

Derived from Latin signum (mark, token), the morpheme sign entered English via Old French signifier (to denote). The suffix -ify (from Latin -ificare) denotes action ("to make"), while -er indicates an agent. The term evolved in 20th-century semiotics (via Ferdinand de Saussure) to describe the perceptible form of a sign (e.g., a word's sound or written shape) as distinct from its abstract meaning.

  3. Dark clouds are often a signifier of approaching rain.

  4. The artist used color as a primary signifier of emotion in the painting.

  5. In semiotics, a red traffic light is a signifier for "stop."
