endow

From Late Middle English endowen, endouen, enduen, indouen, indw (“to provide with assets, a livelihood, or privileges; to bestow, grant; (figuratively) to favour; to endow”), from Anglo-Norman endouer, from Old French en- (prefix meaning ‘in, into’) + douer (“to endow”) (from Latin dōtāre (present active infinitive of dōtō (“to endow”)); modern French douer). Dōtō is derived from dōs (“dowry; endowment, gift”) (ultimately from Proto-Indo-European *deh₃- (“to give”)) + -ō (suffix forming regular first-conjugation verbs).
