Forms

praesūmptiō f (genitive praesūmptiōnis); third declension[1]

Etymology

It is from Latin praesūmō (“to take beforehand”) + -tiō.[2][1][3]

Earliest recorded meaning

It is first found in Seneca,[4] who writes in his letters that we give much weight to the presumption of all men, that is, to what everybody assumes.[2]

Semantic evolution

Pliny the Younger uses it for enjoying something in advance: the anticipation of what one longs to reach is itself pleasant.[2][5] In rhetoric Quintilian uses it for the figure the Greeks called πρόληψις (prólēpsis), answering an opponent's objections before he makes them.[2][5] Apuleius uses it for obstinacy, of someone made proof against the pain of blows.[2]

In Ecclesiastical Latin it came to mean boldness, presumption and arrogance, and in law a presumption, a probable conjecture about an uncertain act.[6] Medieval Latin used it for a high-handed or arbitrary act, effrontery and violence, for disobedience, for a misdeed and for usurpation.[7] Through Old French and Late Latin it is the source of English presumption.[8]
