doddypoll (n.)

c. 1300 (late 12c. as a surname), polle, "hair of the head; piece of fur from the head of an animal," also (early 14c.) "head of a person or animal," from or related to Middle Low German or Middle Dutch pol "head, top." The sense was extended by mid-14c. to "person, individual" (by polls "one by one," of sheep, etc., is recorded from mid-14c.)

Meaning "collection or counting of votes" is recorded by 1620s, from the notion of "counting heads;" the sense of "the voting at an election" is by 1832. The meaning "survey of public opinion" is recorded by 1902. A poll tax, literally "head tax," is from 1690s. Literal use in English tends toward the part of the head where the hair grows.

c. 1200, doten, "behave irrationally, do foolish things, be or become silly or deranged," also "be feeble-minded from age," probably from an unrecorded Old English word akin to Middle Low German and Middle Dutch doten "be foolish, be out of one's mind," all of which are of unknown origin, or directly from these words.

Century Dictionary and OED compare Dutch dutten "take a nap; mope;" Icelandic dotta "to nod, sleep;" Middle High German totzen "take a nap." Wedgwood writes, "The radical sense seems to be to nod the head, thence to become sleepy, to doze, to become confused in the understanding."

From late 15c. as "be infatuated, bestow excessive love." Also in Middle English "to decay, deteriorate," in reference to rotten timber, etc. (mid-15c.). There was a noun dote "fool, simpleton, senile man" (mid-12c.), but Middle English Compendium considers this to be from the verb. Related: Doted; dotes; doting.

late 14c., "imbecile, one who is in dotage or second childhood;" see dote (v.) + -ard. Sense of "one who dotes, one who is foolishly fond" (c. 1600) is now rare or obsolete. Other noun derivatives of dote, all in the sense "fool, simpleton" in Middle English were dotel (late 14c.), doterel (late 15c.), doti-poll (c. 1400; see doddypoll).
