Forms

clāriō (genitive clāriōnis); third declension[1][2] It is also spelled clārō.[2][1]

Etymology

It is from Latin clārus (“clear”),[1][3] and the DMLBS compares Old French clairon.[4]

Earliest recorded meaning

The earliest dated use quoted is from 1349, an English account that pays for small pennons for the trumpets and clarions, for the Christmas feast and for warlike deeds.[4]

Semantic evolution

Niermeyer glosses it as a clarion,[2] the DMLBS as a war trumpet,[4] and Köbler as a trumpet or signal horn.[1] The English word, recorded in the early 14th century, comes from Old French and directly from this Medieval Latin word.[3]
