cost: [13] In Latin, something that cost a particular price literally ‘stood at or with’ that price. The Latin verb constāre was formed from the prefix com- ‘with’ and stāre ‘stand’ (a relative of English stand). In Vulgar Latin this became *costāre, which passed into English via Old French coster (the derived noun arrived first, the verb a couple of decades later). The adjective costly is a 14th century formation.

c. 1200, from Old French cost (12c., Modern French coût) "cost, outlay, expenditure; hardship, trouble," from Vulgar Latin *costare, from Latin constare, literally "to stand at" (or with), with a wide range of figurative senses including "to cost." The idiom is the same one used in Modern English when someone says something "stands at X dollars" to mean it sells for X dollars. The Latin word is from com- "with" (see com-) + stare "to stand," from PIE root *sta- "to stand" (see stet).
