Etymology

It is inherited from Middle English prosperous, also prosperose, prosperus and prospereux,[2] borrowed from Old French prospereus,[3][4][5][2] from prosperer (“to prosper”),[3][6] with the suffix -ous.[6][4] Etymonline and the MED also name the Anglo-Latin form Medieval Latin prosperosus and the Anglo-French prosperous as possible sources.[3][2] The revised OED instead treats it as formed in English from Latin prosper (“favourable, fortunate”) and -ous, comparing prosperosus (1432 in a British source), Middle French prospereux and Italian prosperoso.[7] The Latin adjective, also prosperus,[8][9] is probably formed from an Old Latin phrase, prō (“for, according to”) and spēs (“hope”), so that it meant "according to one's hope".[9][8] Klein relates spēs to Old English spēd (“success, prosperity”), the source of speed, and to spatium (“space”).[9] The Anglo-Norman verb prosperer, to foster or to be successful, is recorded from about 1360–79.[10]

Earliest recorded meaning

Bringing success; favourable, auspicious: about 1425, in the “Book of Foundation of St Bartholomew's”.[7][3]

Semantic evolution

The first sense was the active one, "bringing prosperity", as in a prosperous wind or voyage; the OED now labels it archaic.[7][6] By about 1450 the word was used of people and their affairs that kept on succeeding, "flourishing, thriving",[7][3] and the MED records it of a reign and of good health.[2] Johnson (1755) defined it simply as "successful; fortunate".[11] The economic sense, "well-off, wealthy", is now the usual one.[7][12]
