Inherited from Middle English infaunt, borrowed from Latin īnfantem, accusative masculine singular of īnfāns, nominal use of the adjective meaning 'not able to speak', from īn- (“not”) + fāns, present participle of for (“to speak”). The verb is from Anglo-Norman enfanter, from the same Latin source. Doublet of infante.
