Pronunciation

  • IPA: /ˈɪnfəntɹi/, /ˈɪnfənt͡ʃɹi/[1]

Etymology

It is borrowed from Middle French infanterie,[2][3][4][5] from Italian infanteria (“foot soldiers”),[2][3][4][5][6] a collective from infante “youth; foot soldier”,[2][3][4][5][6] from Latin infans (“infant”).[2][3][4][5] It is related to infant.[2][3][1]

Earliest recorded meaning

The body of foot soldiers; the part of an army that fights on foot (1579).[7][3][5]

Semantic evolution

Etymonline explains the Italian word as a force made up of those too inexperienced or low in rank to serve in the cavalry.[4] The word also meant, humorously, “infants collectively” (1613–16).[7][4] It has otherwise kept its military sense,[7] applied to soldiers who fight on foot and to the branch of an army they make up.[2][5][6]
