Here's how this'll go:
You can submit any word(s) you want, as long as you really love them! They can even be untranslatable into English, or in a foreign language! Brighten someone's day with some words! It'd also be neat to hear why you like the words, I think it'd be interesting! Let's get nerdy while getting to know each other!
I'll start:
Sonder: The realization that each passerby has a life as vivid and complex as your own.
Kuidaore (from Japan, 食い倒れ): To ruin oneself by extravagant eating/To eat oneself into bankruptcy
Vellichor: The strange wistfulness of used bookshops.
Aloof: Conspicuously uninvolved and uninterested, typically through distaste.
Cantankerous: Bad-tempered, argumentative, and uncooperative.
