Etymology

It is inherited from Old English canon (“rule, decree of the Church”), from Late Latin canon (“Church law”),[1][2][3] in classical Latin a measuring line, rule, reinforced in Middle English by Old French canon,[2][5][3] from Greek κανών (kanṓn, “straight rod, rule, standard”),[1][2] probably from kánna, reed (see cane),[2][1] though Beekes favours a Pre-Greek origin.[1]

Earliest recorded meaning

A rule or decree of the Church: about 890, in Alfred.[6][2]

Semantic evolution

Canon law is from about 1340.[6] The central part of the Mass is from the 13th century.[3] The books of the Bible accepted as authentic are from 1382 (about 1400 in Etymonline),[6][1] later extended to secular works of admitted authority,[1] and a general rule or principle is from the late 14th century.[1] A standard of judging is from 1601.[2][6] The musical sense is 16th-century.[3]
