heft

Etymology

The noun is derived from Late Middle English heft (“heaviness; something heavy, a weight”), from heven (“to lift, raise”) + -th (suffix denoting a condition, quality, state of being, etc., forming nouns), by analogy with the development of weft from weven (modern English weave), etc. (also compare words like cleft from cleave, and theft from thieve, where the development occurred in Old English or earlier languages). The English word is analysable as heave + -t (suffix forming nouns from verbs). The verb is probably derived from the noun.
