Origin & History of “cost”
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.
