Or is it simply hysteria which produces what is to-day termed "the profiteer?" It is probable that the modern profiteer is the same person whom we formerly called "the grafter, the extortioner, the robber, the gouger." ["Legal Aid Review," April 1920]
profitless (adj.): 1590s, from profit (n.) + -less.

profligate (adj.): 1520s, "overthrown, routed" (now obsolete in this sense), from Latin profligatus "destroyed, ruined, corrupt, abandoned, dissolute," past participle of profligare "to cast down, defeat, ruin," from pro- "down, forth" (see pro-) + fligere "to strike" (see afflict). Main modern meaning "recklessly extravagant" is 1779, via notion of "ruined by vice" (1640s, implied in a use of profligation). Related: Profligately. As a noun from 1709.

The literal and figurative senses both were in Latin, but English, having already deep, employed this word primarily in its figurative sense. Related: Profoundly.

progenitor (n.): late 14c., from Anglo-French progenitour (mid-14c.), Old French progeniteur (14c.) and directly from Latin progenitor "ancestor, the founder of a family," agent noun from progenitus, past participle of progignere (see progeny).
