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’ [15] 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’. |
