He's great for that, in part his created words generally sound like they could be real.
Reading a lot of older scifi can also be a good vocabulary booster in general, since so much of it uses (often dated) technical terms to describe how various wonder-gadgets work. I've been working my way through Astounding this year and the 30s and 40s alone introduced me over a dozen words I'd never run into before.
E.E. "Doc" Smith had a cute trick in his Lensmen series where the telepathic translation function of the titular Lenses would permanently assign a new word to any concept, object or phenomenon that couldn't be defined to the "listener" in comprehensible terms and from then on every Lens everywhere would consistently use the neologism when needed. For the POV characters this mostly comes up when dealing with species who have a "biological extension into hyperspace" like the Palainians, resulting in words like "dexitroboping" (which isn't quite farming, or mining, an artistic endeavor or some kind of reproductive activity, but might have something to do with any or all of those) and "emfozing" (which would probably be impolite to mention in mixed company if Palainians understood the concept of politeness).
The books never mention it, but presumably a lot of things merely three-dimensional beings regard as perfectly normal get their own neologisms assigned to them for Palainians and listeners from similar ZZZZZZZZZ-code species, since they doubtless find them equally alien to their experiences. You'd have to be an Arisian or stable at the third level of stress (ie one of the Kinnison kids) to be able to "look at the software" of the Lens translation system to determine how a Palainian "hears" the concept of (say) "the taste of really spicy chili" when a Terran Lensman starts going on about it.
