Here’s a fun word for you: bii’nda’a’néhé refers to a gym, or more literally a place within which you play.
Take the first part of the word, bii’. This is the part of the word that means within, or inside.
Remember the word from a few days ago, daané’é. Notice that the rest of the word, nda’a’néhé is, more or less, a form of of daané’é. But in this case, it functions more as an adjective than a noun. Can you see the similarity?
