Origin & History of “blow”
there are three distinct blows in English. The commonest, the verb ‘send out air’ (OE), can be traced back to an Indo-European base *bhlā-. It came into English (as Old English blāwan) via Germanic *blǣ-, source also of bladder. The Indo-European base also produced Latin flāre ‘blow’, from which English gets flatulent and inflate. The other verb blow, ‘come into flower’ (OE), now archaic, comes ultimately from Indo-European *bhlō-. It entered English (as Old English blōwan) via Germanic *blo-, from which English also gets bloom and probably blade. A variant form of the Indo-European base with -s- produced Latin flōs (source of English flower) and English blossom. The noun blow ‘hard hit’ (15th c.) is altogether more mysterious. It first appears, in the form blaw, in northern and Scottish texts, and it has been connected with a hypothetical Germanic *bleuwan ‘strike’.
