OriginMid 18th century (in the sense 'separate into simpler constituents'): from French décomposer, from de- (expressing reversal) + composer. compost from Late Middle English: Garden compost and fruit compôte do not seem to have much in common, but they both derive from French compôte ‘stewed fruit’. This comes from Old French composte, from Latin compositum ‘something put together’—source of compose (Late Middle English) and decompose (mid 18th century), composition (Late Middle English), and component (mid 17th century). Compost has been used in the gardening sense since the late 16th century. The Latin word was formed from com- ‘with’ and the irregular verb ponere ‘put, place’. From this we also get impose (Late Middle English) ‘place (up)on’; oppose (Late Middle English) ‘place against’; positive and posture (late 16th century); preposition (Late Middle English) something put in front, and suppose (Middle English) literally something placed from below.
