Etymology

From Middle English her, heer, hær, from Old English hǣr, from Proto-West Germanic hār, from Proto-Germanic hērą (“hair”), from Proto-Indo-European *kes- (“to scrape, comb”). Cognate with Saterland Frisian Hier, Híer (“hair”), West Frisian hier (“hair”), Cimbrian haar, har (“hair”), Dutch haar (“hair”), German and Low German Haar (“hair”), Luxembourgish Hoer (“hair”), Mòcheno hor (“hair”), Yiddish האָר (hor, “hair”), Danish, Norwegian Bokmål, Norwegian Nynorsk and Swedish hår (“hair”), Faroese and Icelandic hár (“hair”). Eclipsed non-native Middle English cheveler, chevelere (“hair”), borrowed from Old French chevelëure (“hair, head-hair, coiffure, wig”). The modern spelling with ai is not a regular representation of the vowel developed from Middle English. Rather, it is from Middle English here (haircloth) influenced by Old French haire.
