Emily Dickinson Lexicon

WAB'BLE, v.i. [W. gwibiaw, to wander, to move in a circular form.]

To move from one side to the other; to vacillate; as a turning or whirling body. So it is said a top wabbles, when it is in motion, and deviates from a perpendicular direction; a spindle wabbles, when it moves one way and the other. A millstone in motion, if not well balanced, will wabble. [This word is applied chiefly to bodies when turning with a circular motion, and its place can not be supplied by any other word in the language. It is neither low nor barbarous.]
