"crestfallen" is a stupid word

Crestfallen is a ridiculous word that means dispirited or depressed. But honestly, it sounds like some forest Frodo would be fighting ogres in, "Across the high plains of Falcar, through mines of Algarthon, deep into the heart of Crestfallen, where secrets and death surely lie." (sounds perfectly cromulent, although I made all of those words up). I get it though, having your head down "fallen crest" blah blah. But it makes you sound so arrogant if you choose that word instead of depressed. I wasn't aware that the word "depressed" made you sound unintelligent in the eyes of those you would communicate with. It's the same as saying the word "apropos" instead of "appropriate". Really it's an artificial means of increasing your intellectual standing with your peers. So in protest I will simply grunt the rest of this post. Og og ger hwarmp spler klo.
