Rotatory
[Adjective]
Webster's Dictionary 1828
1. Turning on an axis, as a wheel;
rotary.
2. Going in a circle; following in succession; as rotatory
assemblies.
3. [This word is often used, probably by mistake, for
rotary. It may be regularly formed from
rotator, but not with the exact sense in which it is used. With
rotator for its original, it would
signify causing rather than being in a circular motion. The true word is
rotary.]
