What does cleaving mean?
"Cleaving" is the present participle of "cleave," a remarkable English word that carries two seemingly contradictory meanings. In its older, physical sense, it means splitting or cutting something apart — most typically driving an axe through wood along the grain, as when a lumberjack is cleaving logs. In its second sense, it means adhering firmly or remaining faithfully attached, as in someone cleaving to tradition or to a loved one. This paradox exists because two unrelated Old English verbs gradually merged into a single modern form: one meant to split, the other to stick. Today the splitting sense dominates everyday speech and appears in phrases like "cleaving the air" or "cleaving wood," while the clinging sense persists chiefly in formal, literary, and religious writing. Few words in English so vividly embody the idea that language can hold opposites together in a single term.
To split or divide something forcefully, especially along a natural line, grain, or seam.
"The axe blade went cleaving through the log in a single blow."
This is the dominant sense in modern usage.
To adhere firmly or cling loyally to a person, group, belief, or practice.
"He spent his life cleaving to the principles his father had taught him."
This sense is now largely literary, formal, or biblical in register.
"Cleaving" is one of the rare English words that is its own opposite: it can mean splitting something apart or clinging tightly together, thanks to two unrelated Old English verbs that merged into one modern form.

Etymology of cleaving
"Cleaving" traces back not to one source but to two distinct Old English verbs that converged by coincidence. The first, "clēofan," meant to split or cut apart and derives from the Proto-Germanic *kleupaną, whose relatives include German "klieben" and Dutch "kloven." The second, "clifian," meant to stick fast and belongs to the same Germanic family as "glue" and "gluten," making them distant cousins. Over the centuries these two verbs collapsed into the single modern form "cleave," leaving present-day "cleaving" able to express both separation and attachment depending on context.

How cleaving is actually used
Because "cleaving" descends from two distinct Old English verbs that happened to converge in form, its meaning depends entirely on context: in woodworking or physical descriptions it means splitting apart, while in moral, religious, or emotional language it means holding fast. The adhering sense survives mostly in formal, literary, or biblical registers ("cleaving unto"), while the splitting sense is common in practical contexts.
Easily confused with cleaving
"Clove" can mean a dried flower bud used as a spice, but it is also the past tense of the splitting verb "cleave" — so "he clove the log" uses the same root as "cleaving."
"Clinging" only means holding fast or adhering, whereas "cleaving" can paradoxically mean either adhering tightly or splitting apart, depending on which of its two historical verbs is intended.
