Origin & History of “clear”

Clear comes via Old French cler from Latin clārus (source also of English claret and clarion (14th c.)). It has been suggested that clārus is related to calāre ‘call out’ (whence English council). Latin derivatives that have come down to English are clārificāre, from which English gets clarify (14th c.), and clāritās, whence English clarity (16th c.). The middle English spelling of the adjective is preserved in clerestory ‘upper storey of a church’ (15th c.) (so named from its being ‘bright’ or ‘lighted’ with numerous windows).
