prost m or n (feminine singular proastă, masculine plural proști, feminine/neuter plural proaste)[1]

Etymology

It is borrowed from Old Church Slavonic простъ (prostŭ, “simple, plain, sincere”), from Proto-Slavic *prostъ (“simple, straight”).[2][3][4][1][5] The Slavic adjective is a compound of the prefix *pro- and a form of the root of “to stand”, so that its first sense was “standing straight, upright”.[6] Wiktionary gives it as Proto-Indo-European *pro-sth₂o-, from *steh₂- (“to stand”).[6][1] Miklosich took “extended, straight” for its first meaning.[7] The Romanian word kept that old sense in its first records.[8]

The Aromanian cognate is prostu (“simple, naive”).[2][9] The Slavic cognates include Bulgarian прост (prost, “simple, stupid”), Serbo-Croatian prost (“simple”) and Russian простой (prostój, “simple”).[10][2] Ciorănescu compares Hungarian paraszt (“peasant”), which Hungarian borrowed from Slavic.[2][11]

Earliest recorded meaning

Tiktin's first record is in the Codicele Voronețean (Acts 19:11), and the DLR quotes the same manuscript with the adverb prostu “abundantly, generously”: God gives to all men freely, dă tuturor prostu.[12][8] Coresi's Evanghelie cu învățătură (1581), MDA2's first record, uses the adverb in the sense “upright”: „Mortul prost șezu și grăi înaintea tuturora” “the dead man sat up and spoke before them all”.[3][8]

Semantic evolution

The 16th- and 17th-century texts use the word in the senses of the Slavonic adjective: “upright”, “sincere, innocent”, and above all “simple, ordinary”.[8][3] From “simple” came “of low birth, common”: Ureche wrote of people „mai mult proști și necărturari” “mostly simple and unlettered”, and Nicolae Costin's chronicle speaks of a man „de neam prost” “of humble family”.[12] A soldat prost was a private.[3][4] Limba proastă meant the vernacular, as against Greek.[12][13] Mardarie's Slavonic–Romanian lexicon of 1649 uses prost to render Slavonic words for “coarse”, “ignorant” and “layman”.[14]

Other senses followed from “common”: “of poor quality” (marfă proastă “shoddy goods”) and, finally, “stupid”, now the main sense.[12][4] Klein's dictionary of 1801 already gives Latin simplex, rudis, rusticus with Hungarian paraszt and együgyű “simple-minded”.[15] The adverb prost “badly” belongs to the same sense.[16][1] Gagauz borrowed the word from Romanian, and Transylvanian Saxon formed prostig on it.[1]
