I maintain that, even in astronomy, rotation implies a rigid
rotation of a patch
of coordinates, and we can say that if
the identified locations on a body (say fluid parcels, or sites in a lattice) are following said coordinates, then we may say the body is "rotating". I am not aware of any other definition of that concept, in any
application. In particular, there is no local
meaning to the term, it is a relationship, which is the main contrast with revolution (when the latter word is reserved for an orbit, not a turntable).
