Pronunciation

Etymology

It is inherited from Middle English assumpcioun, borrowed from Old French asompsion, assumpcion (modern French assomption),[2][3] and directly from Latin assumptiō, assumptiōnem, a taking up, receiving, adoption,[2][4] from assumptus, past participle of assūmere, to take up, take to oneself (see assume).[2][4][5]

Earliest recorded meaning

The reception of the Virgin Mary into heaven, and the feast of 15 August that commemorates it: 1297 in the OED, about 1300 in Etymonline.[6][2]

Semantic evolution

Reception into heaven in general is from 1577.[6] The taking of food into the body (1599) and elevation to office (1642) are obsolete senses.[6] Taking a form or character upon oneself, or taking office, is from 1646.[6] The logical sense of a minor premise is also recorded,[2][7] the act of taking for oneself is from the 1580s, and something taken for granted from the 1620s.[2] Hoad places both the taking for granted and the sense of a postulate in the 17th century.[3]
