Etymology
It is the participle of probō (“to approve, test”), used as an adjective.[1][2][3] The verb is from probus (“good, upright”), which de Vaan derives from Proto-Italic *pro-f(w)-o- (“favourable”) and Proto-Indo-European *pro-bʰ(h₂)u-o-, cognate with Sanskrit प्रभु (prabhú, “excelling”).[4]
Earliest recorded meaning
The OLD's earliest quotation is Accius: “to be approved by the good rather than by the many”.[1]
Semantic evolution
It is regarded with approval, of good repute or esteemed, as Cicero's steady and esteemed life and his orator who is not only acceptable but approved.[1] With a dative it is acceptable or pleasing to someone, as in an old prayer quoted by Macrobius asking that the city be more acceptable to the gods.[1]
In medieval Latin it is “worthy of credit”.[5]
