Philosophy: True by virtue of the way things in fact are and not by logical necessity.
‘that men are living creatures is a contingent fact’

Origin
Late Middle English (in the sense ‘of uncertain occurrence’): from Latin contingere ‘befall’, from con- ‘together with’ + tangere ‘to touch’. The noun sense was originally ‘something happening by chance’, then ‘a person's share resulting from a division, a quota’; the current sense dates from the early 18th century.
