We all know 'it pays to increase your word power', but I feel sometimes authors toss in words that just don't fit. You'll be reading along a concrete line, then here's a big fat old abstract monster staring you down. It's not a matter of knowing meaning. It's a matter of interrupting an otherwise fun read.
I know what you're talking about, Bluntforcetrauma. I've critiqued stories before that had such issues, and found the words to be eyesores instead of helpful to the story. They can take away from the 'flow' of the writing, which really throws me way off when reading.
I think the problem isn't whether or not the word works, so much as whether the word works for the author or not. Like the saying goes, 'To Each His Own'. So if something doesn't work for you, that might not reflect on whether it works for someone else.
I remember one critique I did, where the author said (and this is a paraphrase with the exception of the word itself), "Such-and-such character
ghosted across the area."
Ghosted didn't work for me; the word 'spirited' would have been more to my taste. But to the author, who I must say is a pretty decent writer in her chosen genre, the word certainly had to have worked, or else she wouldn't have used it.
So basically, it's a matter of taste. What works for you might not work for me, and what works for me might be appalling to you. In writing, a lot of stuff is subjective, and I think this is simply a matter of personal opinion.
