The building blocks of English

Affixes

-ier

Also ‑yer.

A person engaged in an occupation or activity.

Either from Middle English, or via French ‑ier from Latin ‑arius.

In examples from Middle English, the ending is a variant of ‑er1: glazier (Old English glæs, glass); brazier (Old English bræs, brass), a worker in brass. In words like carrier and occupier the ending is ‑er1 with the i converted from the final y of the stem. A few are spelled ‑yer, usually following a stem ending in w: lawyer, sawyer.

From the sixteenth century onwards, many French words ending in ‑ier have been brought into English: brigadier, cavalier, costumier, croupier, financier, fusilier, hotelier. See also ‑eer.
