Pronunciation

Forms

arroser[1] The form arrouser existed beside arroser from the 13th to the 17th century.[2] Vaugelas recommended arroser, and Marguerite Buffet called arrouser an old pronunciation.[3]

Etymology

It is inherited from Vulgar Latin *arrōsō, an alteration of Late Latin arrōrō (“to cover with dew”) after rōs (“dew”).[2][4][5][6] That verb is formed from ad- and rōrō (“to be wet with dew, to bedew”), from the stem of the noun for dew.[2][7] Bloch and Wartburg note that the Late Latin verb is found in late authors from Gaul, and that the Vulgar Latin verb replaced classical irrigō.[4]

Compare Old Occitan arozar.[4]

Earliest recorded meaning

It is first found in Wace in 1155, meaning to moisten.[5][7] Wace says of the Virgin's flowering rod that it was ne moillée, ne arosée “neither wetted nor watered”.[3]

Semantic evolution

Beside the general sense “to pour a liquid on”, used from the 12th century of tears and blood, the verb specialised in geography for a river watering the land it crosses (1265) and in farming for watering plants, then irrigating (1538), and for sprinkling a floor before sweeping (1834).[2] Familiarly, with rain as the subject, it means to drench someone, hence se faire arroser.[2][8]

The sense “to add alcohol to, to accompany with drink” dates from 1719, and was preceded by Old French arouser a food “to dip it in wine”.[2] From it came “to celebrate by drinking” (1829), with arroser ses galons in army slang (1828) and ça s'arrose (1934).[2][9] Figurative uses include “to lavish gifts on someone” (1258 to the 17th century), “to hand out money to” (1792, often with a hint of bribery), and “to shell, to rake with fire” (1915).[2]
