There are very, very few terms that Trek actually coined, aside from species names and such. "Phaser" and "photon torpedo" and, I think, "impulse drive" are original to Trek, and I don't think teleporters had been called transporters before. "Warp drive" predates Trek, but it seems to have originated "warp speed" and "warp factor." And it debuted "Class M" to refer to Earthlike planets, as well as terms for telepathy like "mind meld." But a lot of terms we tend to associate most with Trek, like "subspace" and "deflector" and "tractor beam" and "Prime Directive," predate it by decades.
