Pronunciation

Forms

coutumier (feminine coutumière, masculine plural coutumiers, feminine plural coutumières)[1] Old French custumier, costumier and coustumier.[2][3]

Etymology

It is formed from French coutume + -ier.[2][4][1] The TLFi compares Late Latin consuetudinarius (“habitual”), used as a legal term in the Middle Ages.[2] The base noun goes back to Latin cōnsuētūdō (“custom”).[5] Littré gives the Old Occitan cognates costumier and cosdumnier.[3]

Earliest recorded meaning

It is first recorded about 1160 in the Roman d'Eneas, in the construction custumier de “in the habit of doing something”.[2][6] Gautier d'Arras uses it the same way: Qui de moi nuire est costumiere (“who is in the habit of harming me”).[3]

Semantic evolution

The adjective was soon tied to coutume in its legal sense, the unwritten customary law of a region, giving droit coutumier and pays coutumier.[6][3] As a noun it named a collection of customary rules (1394 for Rey, 1396 for the TLFi).[6][2] In the old law it could also mean a commoner, as opposed to a noble.[3][2] The sense “usual, done as a rule” of things is recorded in 1460.[2]

The personal sense survives mainly in être coutumier du fait, said of someone who has done the same, usually blameworthy, thing before.[7][3] In the French of Africa, the Indian Ocean and New Caledonia, coutumier is used of whatever belongs to local tradition, as in mariage coutumier.[6] Chef coutumier is a traditional chief.[7]
