Um, You Know, Predicates Are a Real Thing, Right?

There's not very many recordings of this language. There are, unlike Japanese, there are no third person pronouns. You can have verbal predicates, nominal predicates, or adjective to vowel predicates in this language. The second person pronoun begins with that, uh, geminate,. It's a sound change that I am fond of, but was never sure if it was actually real.
