type of ape, c.1400, babewyn, earlier "a grotesque figure used in architecture or decoration" (early 14c.), from Fr. babouin "baboon," from O.Fr. baboin "ape," earlier "simpleton, dimwit, fool" (13c.), also "gaping figure (such as a gargoyle)," so probably from O.Fr. baboue "grimacing;" or perhaps it is imitative of the ape's babbling speech-like cries. Ger. Pavian "baboon" is from Du. baviaan, from M.Du. baubijn, a borrowing of the O.Fr. word.
