My favorite word is superfluous. I like that it's spelled SUperFLUous but it's not pronounced that way. It's also a much more fun way to say "too much."
I enjoy words that are better ways to say something easy such as penchant (better than "I like"), vice (better than "instead of"), adjacent (better than "next to"), and verbose (better than "using way too many words.")
I appreciate indulgent and excess probably because I enjoy being self-indulgent and living in excess. Plus, I think that s's and x's are pretty.
J's, k's, z's, and q's are also pretty. So I also like juxtapose, cognizant, oblique, and kitchy.
