doddered

Etymology 1
Apparently originally a derivative of. It is not clear whether it was a contaminated form of or a mistaken spelling of  (“doddered oak” for “doddard oak”; cf. ), while the matter is complicated by the earlier use of  or  in the same sense. In later use there has been association with and perhaps with  and its cognates.
