Etymology

It is inherited from Middle English clarifien, borrowed from Old French clarifier,[2][3][4] from Late Latin clārificō (“to make clear; to glorify”),[2][3] from clārificus (“brilliant”), from clārus (“clear”) (see clear) and the root of faciō (“to make”).[2][3]

Earliest recorded meaning

To make illustrious or glorious, make known: before 1325 in Barnhart, the early 14th century in Etymonline, a sense now obsolete.[2][3]

Semantic evolution

To make clear and pure, especially of liquids such as liquors, is from the early 15th century (about 1430).[3][5] To light up or brighten is from 1398.[5] To clear the mind of error is from 1642,[5] and the figurative sense, to free a subject from obscurity, make intelligible, from 1823.[3][5] The New Oxford notes an early sense, to set forth clearly.[6] Clarification is from 1612.[2]
