What does cleave mean?
Cleave is a verb with a rare and fascinating double life: depending on context, it means either to split something apart or to hold fast to something. Its dominant modern sense is physical division — cleaving wood along the grain, splitting stone, or cutting meat — usually with forceful tools such as axes, wedges, or cleavers. Yet historically the word also meant to adhere firmly, as in the biblical injunction to 'cleave unto' one's spouse, a sense now confined to literary, legalistic, and religious prose. This makes cleave one of English's best-known contronyms, words that are their own opposites. The two meanings arise from different Old English ancestors that happened to converge in form. Today the splitting sense prevails in both Britain and America, often appearing in technical, carpentry, and literary contexts, while the sticking sense lends the word an air of solemnity when writers deliberately revive it.
verbTo split or sever something, especially along a natural line or grain; or, archaically and formally, to adhere firmly and faithfully to something.
- To split or divide something, especially wood, along its grain, typically with an axe or blade.
- (Archaic or literary) To cling, adhere, or remain faithfully devoted to someone or something.
"With one swift blow of the axe, he cleaved the log cleanly in two."
"The butcher cleaved the haunch of beef with a single stroke of the cleaver."
"In the King James Bible, a man is instructed to cleave unto his wife, holding fast to her all his days."
Cleave is a famous contronym: it means both to split apart and to stick together — one word carrying its own opposite.

Etymology of cleave
Cleave descends from two distinct Old English verbs: clēofan, meaning to split, which came from the Proto-Germanic root *kleuban-, and clifian, meaning to stick, from a different Germanic root. Over the Middle English period the two forms merged in spelling and pronunciation, producing the modern contronym. Germanic cognates of the splitting sense include Dutch kloven and related forms in other Germanic languages; the English words cleft, cloven, and the 'clove' of garlic all trace back to the same Old English root as the splitting verb.

How cleave is actually used
Cleave is notable as a contronym — a word whose two senses are opposites. The splitting sense is the only one in common modern use; the adhering sense survives mainly in literary and biblical language ('cleave to', 'cleave unto'). The verb is somewhat formal or technical today, and everyday speakers often prefer 'split', 'cut', or 'chop' instead.
