"elite Turkish infantry," 1520s, from French janissaire (15c.), from Italian giannizzero, from Turkish yenicheri, literally "new troops," from yeni "new" + cheri "soldiery." Formed 1362 from slaves and prisoners of war, until late 17c. largely recruited from compulsory conscripts and converts taken from Christian subjects. In later times Turks and other Muslims joined the corps because of the various privileges attached to it; abolished 1826.
