- certain:  Certain comes ultimately from Latin certus ‘sure, fixed’, which derived from the past participle of the verb cernere ‘decide’. The Latin adjective was extended in Vulgar Latin to *certānus, which passed into English via Old French certain. Other English words based on certus include certify  (from late Latin certificāre) and its derivative certificate, and certitude  (from late Latin certitūdō).
