From Middle English auctour, from Anglo-Norman autour, from Old French autor, from Latin auctor, from augeō (“to increase, originate”). The h, also found in Middle French autheur, is unetymological as there is no h in the original Latin spelling. The OED attributes the h to contamination by authentic. Doublet of auteur.
