blasto-comb. form

Origin: Of multiple origins. Partly a borrowing from French. Partly a borrowing from Greek. Etymons: French blasto-; Greek βλαστο-.

Etymology: < French blasto- (in e.g. blastocarpe blastocarpous adj. ) and its etymon Hellenistic Greek βλαστο-, combining form (in e.g. βλαστοκοπεῖν to cut off young shoots) of ancient Greek βλαστός sprout, germ ( < the stem of βλαστάνειν to bud, sprout, grow, of unknown origin); compare -o- connective. Compare blast n.², -blast comb. form.First attested in borrowings from French, from the early 19th cent., e.g. blastophore n. Formations within English are found from the mid 19th cent. Compare scientific Latin blasto- (formations in which are found from the early 19th cent.), German blasto- (formations in which are found from the second half of the 19th cent.).

Used as the first element in many technical terms, chiefly in Biology, with the sense of ‘germ’ or ‘bud’.
