Word History

Etymology

Noun

Middle English, from Old English blǣst; akin to Old High German blāst blast, blāsan to blow, Old English blāwan — more at blow

Verb

Middle English blasten, derivative of blast blast entry 1

Combining form

combining form from Greek blastós "shoot, bud, embryo, germ" — more at -blast

Noun combining form

combining form from Greek blastós "shoot, bud, embryo, germ," noun derivative from the base of blastánein "to bud, sprout, grow," of obscure origin

Note: The supposed base *melōdh- "protuberance, head" in Julius Pokorny, Indogermanisches etymologisches Wörterbuch (citing, in addition to blastós, Sanskrit mūrdhan- "head," Greek blōthrós "tall," Old English molda "top of the head") is improbable as an Indo-European root; a substratal origin is possible, but the semantic links are weak.
