woo

From Middle English wowen, woȝen, from Old English wōgian (“to woo, court, marry”), of uncertain origin. Cognate with Scots wow (“to woo”). Perhaps related to Old English wōg, wōh (“bending, crookedness”), in the specific sense of "bend or incline (some)one toward oneself". If so, then derived from Proto-Germanic *wanhō (“a bend, angle”), from Proto-Indo-European *wonk- (“crooked, bent”), from Proto-Indo-European *wā- (“to bend, twist, turn”); related to Old Norse vá (“corner, angle”).
