Word History

Etymology

Middle English, from Latin prosperus "agreeable to one's wishes, successful, (of omens) propitious" (going back to *pro-sparo-, from pro- pro- entry 2 + *sparo-, going back to Indo-European *sph1-ró- "thriving") + -ous -ous — more at speed entry 1

Note: An apparently traditional explanation is recorded by the fourth/fifth century grammarian Nonius Marcellus, namely, that prosperus was in origin from the phrase prō spērē "in conformity with one's hope" (spērē being taken as a variant of spē, ablative of spēs "hope"), though this may best be regarded as a folk etymology. It fails to account for the short e in prosperus.
