crēdulitās f (genitive crēdulitātis); third declension[1]
Etymology
It is from crēdulus “credulous” with the suffix -tās; ⟨crēdulus⟩ is from crēdō “to believe”, which de Vaan traces to Proto-Indo-European *ḱred-dʰeh₁- (“to place in the heart, believe”).[2][1][3]
Earliest recorded meaning
Gaffiot's earliest citation is Plancus, in a letter in Cicero's collection, and Lewis & Short note it is never in Cicero himself and becomes frequent after Augustus.[4][5]
Semantic evolution
It was easiness of belief, credulity, trustfulness, as in Curtius and Quintilian.[2][4]
In Christian and Medieval Latin it was religious faith, belief; trust, credit; reliability; credibility.[6][7] British Medieval Latin used it also for an article of belief, accreditation, and litterae crēdulitātis letters of credence.[8] English credulity (early 15th century) first meant “faith, belief”.[9]
