This etymology is completely logical here. The Celtic Cornish BLĒS, (flour), BLEUJENN (flower) = Welsh, BLODEUIN, are from this same root that is presented, as also their Germanic parallels, BLAD, et cetera. However, a slight variation may also contribute to it being otherwise substrate in contrast to the Old English form for bloom from the Proto-Germanic form *BLΌSMAZ which also answers to Ancient Greek βλάστημος (blástēmos, “increase, growth”), Ancient Greek βλαστός (blastós, “sprout, shoot, sucker”) from Ancient Greek βλαστάνω (blastánō, “to bud, sprout, grow”)<ref. Liddle & Scott (1869)</ref>, perhaps ultimately from Proto Indo-European root *BH2L (to split, separate, as with flower development); but not necessarily via the normal paths, since Φ would normally be the initial letter of any Greek kinship. Compare Semitic √PĀLAL > Sanskrit PHAL (separate), ultimately > L. FLOS, et cetera, with their Classical fricatives.
means 'Absolutely not; means 'Exceedingly unlikely'; means 'Very dubious'; means 'Questionable'; means 'Possible'; means 'Probable'; means 'Likely'; means 'Most Likely' or *Unattested; means 'Attested'; means 'Obvious' - only used for close matches within the same language or dialect, at linkable periods. '2' inserted in root words stands for a laryngeal to represent an 'a' that does not exist. √ means original or earliest root.

Isn't it also used when somebody stops being shy/reserved? --Backinstadiums (talk) 09:23, 23 October 2020 (UTC)
