what is the etymology of "motor"? I ask this, because I have been looking at the use of the words "motor" and "engine" - how they are synonyms and how they are used differently.
- A motor is something that makes something move, or that generates movement. An engine just transforms energy in some way - it might not even have any moving parts. SemperBlotto 14:26, 18 October 2008 (UTC)
