【How-to】How do you spell dote

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.
