masc nom sg of ajeyya (ptp)
Etymology. a- (not) + jeyya (conquerable, from √ji 'to overcome'; cognate with English 'jet' in the sense of throwing force, Latin jacere 'to throw'). The root ji originally meant 'to throw against, to overcome by force', preserved in Sanskrit jaya- 'victory'. The prefix a- negates: ajeyya = 'not-conquerable', hence 'unconquerable'.
