Emily Dickinson Lexicon

WAD'DLE, v.i. [This seems to be a diminutive formed on the root of wade, L. vado, to go; G. waten, to wade; watscheln, to waddle.]

1. To move one way and the other in walking; to deviate to one side and the other; to vacillate; as, a child waddles when he begins to walk; very fat people walk with a kind of waddling pace. So we say, a duck or a goose waddles.
2. To walk with a waddling motion. And hardly waddles forth to cool. – Swift.
