From LJ: What are your favorite and least favorite words? Any reasons why?

All my favorite words sound like Exalted names (or name fragments). Resplendent. Officious. Effervescent. Innocuous.

Of course, I have other favorite words in other contexts, but they're rather more... un-PG-13. ;)

Least favorite words? The ones I can't pronounce or spell. Like mischievous or novitiates.
