Etymologically, the entry records: From Middle English blewe, from Anglo-Norman blew (“blue”), from Middle French bleu, from Old French blöe, bleve, blef (“blue”), from Frankish *blāu (“blue”) (perhaps through a Late Latin blāvus, blāvius (“blue”) attested from Isidore of Seville), from Prot… Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear.

Etymology

From Middle English blewe, from Anglo-Norman blew (“blue”), from Middle French bleu, from Old French blöe, bleve, blef (“blue”), from Frankish *blāu (“blue”) (perhaps through a Late Latin blāvus, blāvius (“blue”) attested from Isidore of Seville), from Proto-Germanic *blēwaz (“blue, dark blue”), from Proto-Indo-European *bʰlēw- (“yellow, blond, grey”). Cognate with dialectal English blow (“blue”), Scots blue, blew (“blue”), North Frisian bla, blö (“blue”), Saterland Frisian blau (“blue”), Dutch blauw (“blue”), German blau (“blue”), Danish, Norwegian and Swedish blå (“blue”), Icelandic blár (“blue”), Latin flāvus (“yellow”), French bleu (“blue”), Middle Irish blá (“yellow”). Doublet of blow. Possibly related also to English blee (“colour”), from Old English blēo (“colour”); but direct derivatives of Proto-Germanic *blēwaz (“blue, dark blue”) in Old English include: Old English blāw and blēo (“blue”), Old English blǣwen (“bluish, light-blue”), blǣhǣwen (“blue-coloured, bluish, violet or purple colour”, literally “blue-hued”). There seems to be a parallel connection in Germanic between words for blue and colour, dually exemplified by Proto-West Germanic *blīu (“colour, blee”) and *blāu (“blue”); and Proto-Germanic *hiwją (“colour, hue”) and *hēwijaz (“blue, purple”). (depressed): Compare typologically Russian тоска́ зелёная (toská zeljónaja) (<+ зелёный (zeljónyj)).
