race

From Middle English race, partially from Old English rǣs (“a race, swift or violent running, rush, onset”), from Proto-West Germanic *rās; and partially from Old Norse rás (“a running, race”); both from Proto-Germanic *rēsō (“a course”), from Proto-Indo-European *h₁reh₁s- (“to flow, rush”). Cognate with Middle Low German râs ("a strong current"; whence German Low German Raas (“mad rush, rage, fury”)), Dutch ras (“a strong whirling current”), Danish ræs, Norwegian and Swedish ras, Norwegian rås.

Mid 16th century. From Middle French raïz, raiz, rais (“root”), from Latin radix (“root”), from Proto-Italic *wrādīks, from Proto-Indo-European *wréh₂ds.

From Middle English racen, rasen (“to come apart; to pick clean, strip; to pull away, snatch; to pull down, knock down; to pull off, strip off; to pluck or tear out; to tear apart”), either:

an aphetic form of arasen, aracen (“to pluck, pull, or tear away or out”), from Anglo-Norman aracer and Old French aracier, esracier, esrachier (“to pull off”) (modern French arracher), from Latin ērādīcāre, the present active infinitive of ērādīcō (“to root out; to annihilate, extirpate”), from ē- (variant of ex- (prefix meaning ‘away; out’) + rādīx (“root”) (from Proto-Indo-European *wréh₂ds (“root”)) + -ō (suffix forming regular first-conjugation infinitives of verbs); or

from Anglo-Norman racer, an aphetic form of aracer (see above).
