Pronunciation

Forms

oiseux (feminine oiseuse, masculine plural oiseux, feminine plural oiseuses)[1] Old French oiseus; the spelling oiseux is found from about 1210.[2][3]

Etymology

It is inherited from Old French oiseus, inherited from Latin ōtiōsus (“at leisure, idle, useless”), from ōtium (“leisure, rest”).[4][5][2][6] Rey notes that the Latin noun is of unknown origin and survived only in Old Occitan.[5] Bloch and Wartburg note that elsewhere in Romance the word is a learned borrowing.[6]

Cognate with Old Occitan ocios, Spanish ocioso and Italian ozioso.[7]

Earliest recorded meaning

It is first found in Chrétien de Troyes's Érec et Énide (1165–1170) as a feminine noun, une oiseuse, a useless thing or idle words.[4][5]

Semantic evolution

In Old French the noun oiseuse also meant idleness, sloth (late 12th century).[4][5] As an adjective it described a thing that serves no purpose, as in parole oiseuse in Chrétien's Chevalier au lion (1176–1181), and a person who does nothing (1181–1190); Jean de Meun has vie oiseuse (1269–1278).[4][5] On oiseus Old French formed the noun oisdive “idleness”, whence the adjective oisif (1271) and oisiveté (about 1330).[6]

The sense “idle” of a person has weakened, since words such as fainéant, paresseux and above all its derivative oisif took it over; the main modern sense is “pointless, leading nowhere”.[5][8]
