The taking of a thing out of where it was. Removal should leave a record, since absence otherwise looks like never-was.
Latin removere (to move back, to take away): re- (back) + movere (to move); removal is the taking of a thing out of the place it had been moved into and kept.
The taking of a thing out of where it was. The root's moving-away should always leave a trace, since an absence with no record of its own cause looks exactly like a thing that never existed.
