Yea well here's the problem. We have two properties, predictability and uniqueness. An IV often infers that the value shouldn't be predictable but that it can be reused whereas a nonce often infers that the value can be predictable but can *never* be reused.

So i'm just trying to figure out how we can communicate to users what properties (predictability and uniqueness) this value needs to have. Unfortunately we have two words and 4 total combinations of properties.
