nigger

Alteration of earlier neger, from Middle French nègre (“a black person”), from Spanish negro. Ultimately from Latin niger (“black”), thus a doublet of negro and noir. The expected Modern English pronunciation would be with /iː/; compare neger. The modern pronunciation with /ɪ/ may be due to influence from the Latin etymon (compare the older Southern US pronunciation of negro with /ɪ/), but compare the dialectal American pronunciations of eagle and eager as /ˈɪɡəl/ and /ˈɪɡɚ/. Compare Danish neger, Swedish neger, German Neger, Dutch neger. First use appears c. 1577, in the writings of Edward Hellowes (fl. 1574–1601).
