apodictic
apo·dic·tic
adjective
1.
of a proposition; necessarily true or logically certain
Origin
From the Latin apodīcticus (“proving clearly”, “demonstrative”), from the Ancient Greek ἀποδεικτικός (apodeiktikós, “affording proof”, “demonstrative”), from ἀποδείκνυμι (apodeíknumi, “to demonstrate”). In turn, from ἀπο- (apo-, “separate, without”), and δεικτικός (deiktikós, “capable of proof”).
