Etymology : In the Middle Ages, clarion was a noun, the name for a trumpet that could play a melody in clear, shrill tones. The noun has since been used for the sound of a trumpet or a similar sound. By the early 1800s, English speakers also started using the word as an adjective for things that ring as clear as the call of a well-played trumpet. Not surprisingly, clarion ultimately derives (via the Medieval Latin clario-) from clarus, which is the Latin word for “clear.” In addition, clarus gave English speakers clarify, clarity, declare (“to make clearly known”), and clear itself.
