    They have lots of moving parts. Lots of really tiny ones that are expelled out of one or both ends.

    Book: "Rocket Propulsion Elements - An Introduction to the Engineering of Rockets" by Georger P. Sutton, references in index: "Solid propellant rocket motors" and "Liquid propellant rocket engines."

    I have and always will go with Sutton's terminology.

    EDIT: For the same basic reasons I believe were behind Sutton's (industry's) choice, I don't call AC/DC motors "engines" nor do I call internal combustion engines "motors."
