Words related to dote

doddypoll (n.)

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."

dotage (n.)

late 14c., "condition of being foolish; foolish love, infatuation," literally "the condition of one who dotes," from dote (v.) + -age. Also from late 14c. as "senility; feebleness or imbecility of mind in old age."

dotard (n.)

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).

dotty (adj.)
1812, "full of dots," from dot (n.) + -y (2). Meaning "silly" is from c. 1400, in dotypolle "dotty poll" (i.e. "dotty head"), in which case the first element is from dote (v.).
fond (adj.)

late 14c., "deranged, insane;" also "foolish, silly, unwise," from fonned, past-participle adjective from obsolete verb fon, fonne (Middle English fonnen) "be foolish, be simple," from Middle English fonne "a fool, stupid person" (early 14c.), which is of uncertain origin but perhaps from Scandinavian. Related: Fonder; fondest.

Meaning evolved via "foolishly tender" to "having strong affections for" (by 1570s; compare doting under dote). Another sense of the verb fon was "to lose savor" (late 14c. in Middle English past participle fonnyd), which may be the original meaning of the word:

Gif þe salt be fonnyd it is not worþi [Wyclif, Matthew v.13, c. 1380]
