As the title suggests, what’s your favourite or most interesting thing about a language you’ve created for your world/s? It doesn’t have to be a fully fledged language either - a few words or names here or there can represent a bigger language behind them.
For one of my languages: making short/pet names by adding a single vowel as a prefix. English does suffixes (Bob —> Bobby, Dad —> Daddy) and I found I was defaulting to that, but by simply adding the vowel in front instead, I was able to keep the ‘cuteness’ of it and still maintain the flavour of my language.
Some examples: Mur (cat) —> umur (kitty); Liss (a character) —> Iliss (her pet name).
I would love to hear your language quirks, so please share!
