Origin: before 950; Middle English cleven,Old English clēofan, cognate with Old High German klioban (German klieben), Old Norse kljūfa; akin to Greek glýphein to carve, Latin glūbere to peel
"to adhere," O.E. clifian, from W.Gmc. *klibajanan, from PIE *gloi- "to stick." The confusion was less in O.E. when cleave (1) was a class 2 strong verb and cleave (2) a class 1 verb; but it has grown since cleave (1) weakened, which may be why both are largely superseded by stick and split.
