Forms
accroître[1] Old French acreistre, then acroistre (before 1220) and Middle French accroistre (15th century).[2][1]
Etymology
It is inherited from Old French acreistre, inherited from Latin accrēscō, formed from ad- and crēscō (“to grow”).[3][2][4][5] The Latin verb was only intransitive in Classical and Late Latin and became transitive in Medieval Latin, but was never reflexive.[3][2] The Old French form was remade after croître into acroistre.[2]
Cognate with Italian accrescere, Spanish acrecer and Old Occitan acreisser.[4][6]
Earliest recorded meaning
It is first found in the mid-12th century in Li Quatre Livre des Reis, translating the Latin amplificet: Deu acreissed le num Salemun “may God make the name of Solomon great”, in the sense “to magnify, give lustre to”.[3][2]
Semantic evolution
From “to magnify” the verb passed to “to increase” an abstract thing (1180, Marie de France) and a possession (before 1220, Henri de Valenciennes), which is still its main sense.[3][2] An intransitive use, “to grow in number and power”, appears in the 13th century;[3] Rey calls it obsolete, though the Académie still gave son revenu accroît in 1932.[2][3] Furetière recorded the legal sense in 1690, of a share that passes to an associate on another's death or absence, and the reflexive s'accroître is found in Commynes in 1498.[3]
Classical French could also say accroître quelqu'un, to give a person more power or honour.[7][6]
