also dotipoll, c. 1400, dotypolle, dodipoll, "stupid person," now obsolete in whatever spelling. The second element is poll (n.) in the original sense of "head." The first element is probably from Middle English dote (n.) "fool, simpleton, senile old man" (mid-12c.), from dote (v.). But it is sometimes said to be from Middle English dodden "to shear, shave."
