Etymology
From Middle English progenitour, from Anglo-Norman progenitour, Middle French progeniteur (Modern French progéniteur), and their etymon Latin prōgenitor, from prōgenitus, perfect participle of prōgignere (“to beget”), itself from prō- (“forth”) + gignere (“to beget”).234 By surface analysis, pro- (“prior, fore-”) + genitor.
