Word History

Etymology

Middle English progenitour, borrowed from Anglo-French & Latin; Anglo-French, borrowed from Latin prōgenitor "individual from whom a person or family is descended, ancestor," agentive derivative of prōgignere "to produce as offspring, bring into being, give rise to" (from prō- pro- entry 2 + gignere "to bring into being, beget, give birth to"), after genitor "father, parent, originator," going back to Indo-European *ǵenh1- "engender, beget" + *-tor/*-tōr, agent suffix, from which also Greek genétōr "father, begetter, ancestor," Sanskrit janitar-, janitá "father, progenitor" — more at kin entry 1

Note: Alternatively genitor has been explained as a new formation based on genitus, past participle of gignere. The older and still somewhat more attractive view sees genitus as the new formation, based on the perfect genuī or on genitor itself, after the connection with the original verbal adjective (g)nātus (going back to zero-grade *ǵn̥h1-to-) became weakened.
