i gotta say one of my fave things about language is when you add random syllables to words or add nonsense words that rhyme

like for example, our girl cat is called minou but sometimes i'll call her "minoutschi". and then instead of saying "minou, du" i'll say "minoutschi dutschi". and when i'm feeling extra silly or loving i'll add a nonsense word, so i'll sweep her off the ground and pet her and say "minoutschi dutschi wutschi"

or sometimes she'll meow outside in the hallway, then wander in my room and start purring loudly while rolling around the ground (she does that when she gets clingy and really wants affection). and so i'll start petting her and she'll be purring and i'll say "du schnurrli wurli" (schnurrli/schnurli is a very common cat name based on the word "schnurren" which means "to pur". which is why it's my affectionate nickname for her when she's purring lol)
