2、infant: [14] Etymologically, an infant is ‘someone who cannot yet speak’. The word comes via Old French enfant from Latin infāns ‘young child’, a noun use of the adjective infāns, originally ‘unable to speak’, which was formed from the negative prefix in- and the present participle of fārī ‘speak’ (source of English fable, fame, fate, etc).The somewhat improbable derivative infantry [16] comes via French from Italian infanteria; this was based on infante, whose original meaning ‘young person’ had shifted to ‘foot soldier’ (a development distantly reminiscent of the use of British English lads for ‘male members of a group, team, etc’).=> fable, fame, fate

As an adjective, 1580s, from the noun.
