Forms
accoutumer[1] Old French acostumer and acustumer, Middle French accoustumer.[1][2][3]
Etymology
It is inherited from Middle French accoustumer, from Old French acostumer,[1] formed from French a- + coutume, and the noun goes back to Latin cōnsuētūdō (“custom, habit”).[4][3][5][6] Littré analyses it the same way.[7]
Cognate with Occitan acostumar, Catalan acostumar, Spanish acostumbrar, Portuguese acostumar and Italian accostumare.[7][1]
Earliest recorded meaning
It is first recorded as acostumer about 1160, in the sense “to get used to something”; the transitive sense “to make someone used to something” follows about 1170.[4][8] The Larousse dates the spelling acustumer to about 1190, in the Livre des Rois.[2]
Semantic evolution
From the 13th century the word was common in legal and narrative prose: Beaumanoir writes of the lawyers who acoustument à pledier before the bailiff (“are used to pleading”), and Joinville has the king ask his sons to make it their habit to wash the feet of the poor.[7] The construction avoir accoutumé de “to be in the habit of” is now archaic or literary.[3][7]
The past participle accoutumé “usual” gave the phrase à l'accoutumée “as usual”.[8] The verb formed a family early: accoutumance (about 1160), désaccoutumer (late 12th century), inaccoutumé (1380) and raccoutumer (1538).[8][5] In modern French it is a more formal synonym of habituer, rare in speech.[9]
English accustom (early 15th century) was borrowed from the Old French verb.[10]
