To the point that if someone does
use the same word repeatedly (when there are perfectly suitable synonyms and
infinite possibilities for just avoiding the word altogether) in a work, it begins to grate. Badly.
I recall reading Interview With A Vampire
and thinking "for Christ's Sake, if she says "preternatural" one more fucking time, I'm going to scream!"
That same word is used frequently in Gail Carriger's "Parasol Protectorate" stories but does not grate as much because a) it is the accepted in-universe term for what the principal character is, and b) she throws in "slang" alternatives such as "soulless" or "soul-sucker" and other less complimentary terms as well.
She also doesn't describe every. last. thing. that Miss Tarabotti does as "preternatural" - unlike Ms Rice who seemed to think that if she didn't describe every last aspect of vampires - their speed, strength, reflexes, ability to fart tunefully or whatever - as "preternatural" we wouldn't understand how special and precious they were.
I've used the word three times already (and avoided it twice) and it's grating on me.
