Pronunciation

Forms

où[1] Old French ut (10th century), o (late 10th century), u (1080) and ou (1050).[2][3] The grave accent, which distinguishes it from ou “or”, dates from 1539.[2][4]

Etymology

It is inherited from Old French ou, inherited from Latin ubi (“where; when”), a relative and interrogative adverb of place without motion, also used of time.[2][5][6][1] Latin “ubi” belongs to the group of the relative quī; comparison with Oscan puf and Umbrian “pufe”, and the compound alicubi (“somewhere”), show that it was originally “*cubi”.[2][7] Wiktionary gives Old Latin cubī, from Proto-Italic *kʷuðei.[1]

Cognate with Italian ove, Old Occitan o and Old Spanish o.[7]

Earliest recorded meaning

The Vie de saint Léger (second half of the 10th century) has ut as a relative adverb of place: Cio fud Lusos ut il intrat “it was Luxeuil that he entered”.[4][2]

Semantic evolution

As a relative adverb of place, où was first used after an antecedent, especially an adverb of place (lai… o “there … where”, late 10th century), and after prepositions from 1176–81 (par ou).[4][2] About 1160–70 it was extended to people and things, meaning “to whom, in which”.[4] Its use without antecedent was common in Old and Middle French, then declined after the 16th century in favour of là où.[2] It has been an interrogative adverb from 1080, and is used of time (le jour où).[3][1]
