Plural:

From Middle English haunten (“to reside, inhabit, use, employ”), from Old French hanter (“to inhabit, frequent, resort to”), of Germanic origin, probably through Gothic *[script?] (haimatjan, “to lead home”), from Proto-Germanic *haimatjaną (“to house, bring home”), from Proto-Germanic *haimaz (“village, home”), from Proto-Indo-European *kōim- (“village”). Cognate with Old English hāmettan (“to provide housing to, bring home”), Old Norse heimta (“to bring home, fetch”) (Swedish hämta); related to Old English hām (“home, village”), Old French hantin (“a stay, a place frequented by”) from the same Germanic source. More at home.
