Etymology

It is borrowed from Old French profond (“deep”), also profund, and directly Latin profundus (“deep, bottomless, vast”),[2][3][4][5] from prō (“forth, before”) and fundus (“bottom”) (see bottom and fund).[2][3][5][6]

Earliest recorded meaning

Of a person, showing intellectual depth, very learned: about 1300 in Barnhart and Etymonline, about 1305 in the OED.[2][3][7] The NODE also says the sense of deep insight came first.[6]

Semantic evolution

Latin used the word both literally and figuratively, but English, which already had deep, used it mainly in the figurative sense,[3] though in the 15th century it was used of deep lakes and wounds.[3] Physical depth is recorded from about 1407,[2][7] deeply felt from about 1400,[3] and intense or thorough, of a state or quality, from 1599.[7] Of reverence or respect, often with the idea of bowing low, it is from 1526.[7] A verb profound, to penetrate or fill, was used from the 15th to the 17th century.[3] Profundity is probably from before 1425.[2]
