Word History

Etymology

Adjective

Middle English blak, blake, going back to Old English blæc, blac "black, (of other colors) dark," going back to West Germanic *blaka- (whence also Old Saxon blak "ink," Middle Low German black, blak, Middle Dutch blak, Old High German blah- only in compounds, as blahfaro "ink-colored, deep blue"), perhaps adjectival derivative of a verb *blakōn- (whence Middle Dutch & Middle Low German blaken "to burn, scorch"), from a verbal base *blak- (whence also Old High German blecken, blec(c)hen "to flash [of lightning], shine, sparkle" < *blakjan-), o-grade ablaut of Indo-European *b^hleg- "shine, be bright" — more at phlegm

Note: For this etymology to work, the original meaning of *blaka- would have been "burned, scorched," then, by a not implausible shift, "blackened by fire," then simply "black." In Old English, blæc is sometimes spelled blac, which creates potential confusion with blāc "bright, shining, pale, pallid," ordinarily not spelled with any indication of vowel length, and sometimes spelled blæc. In Middle English potential confusion is to some degree increased by lengthening of vowels in open syllables, revealed by such spellings as blaak and blake for blak. Old English blāc emerges in Middle English, in a small number of texts, as blok, though blak(e) is found in some Midland and northern texts. — Presumably related to *blaka- is an adjective *blank- with infixed n—see blank entry 1. In Germanic, alongside *blek-/*blak- there is a semantically similar strong verb with a diphthong *blīk-/*blaik-/*blik- along with an adjective *blaik- "bright," the source of Old English blāc cited above—see bleach entry 1.

Noun
