Pronunciation

Forms

détour m (plural détours)[1] Old French destor, destour in the 13th century; the spelling détour dates from the 16th century.[2]

Etymology

It is a deverbal noun from French détourner (“to turn aside”), first as Old French destor.[3][4][2][1] détourner (first desturner, 1080) is itself from French tourner with the prefix dé-,[5] and that verb comes from Latin tornō (“to turn on a lathe”).[6][1] Littré analysed the noun instead as the prefix and tour3.[7]

Earliest recorded meaning

It first appears about 1165 in Chrétien de Troyes's Cligès, in en un destor, for an out-of-the-way place, a hiding place.[3][5][4]

Semantic evolution

Early in the 13th century en destour meant "secretly", and in the same century the word was used figuratively for a pretext or subterfuge.[3][5][8] In 1538 Robert Estienne's dictionary has the plural for winding paths, and in 1552 it is first found for the place where a road or river changes direction and a way longer than the direct one;[3][5][2] Rabelais writes of le grand destour du chemin (1548).[3][5][2] The plural was applied to indirect, veiled speech (1553) and to the secret recesses of the heart (1690), while être sans détour expressed frankness (1835).[5] English borrowed detour in 1738, at first mostly in figurative uses.[9]
