cover: cover: [13] Cover comes ultimately from Latin cooperīre, a compound verb formed from the intensive prefix com- ‘completely’ and operīre ‘cover’ (a relative of aperīre ‘open’, from which English gets aperient). It passed into English via Old French cuvrir or covrir. Derivatives include coverlet [13] (in which the final element represents not the diminutive suffix but French lit ‘bed’, the word being a borrowing from Anglo-Norman covrelit, literally ‘bed-cover’) and kerchief (literally ‘head-cover’), as in handkerchief.
=> aperient, discover
