It sounds like you might be thinking about the origin of the word "deer." Here's a bit about that:
* The word "deer" comes from Old English. It's been used to describe these animals for centuries.
* The word is related to other Germanic languages, such as German "Tier" (animal) and Dutch "dier" (animal).
* It's thought to be connected to a Proto-Germanic word that meant "wild animal" or "beast."
So, while deer didn't come from a language, the word we use to call them does have a fascinating history!
