If you can use the rulebook language, but we do have jargon that is acceptable and understood in our game. I would not worry about using that jargon as long as it is accurate and easily understood. I do not know anyone that would get upset (not in real life) if you said "Key" or "Baseline." If this is what you are really worried about or an assignor is worried about this, then you or they have too much to worry about. These terms are not the same as saying "over the back" or "moving screen" while calling fouls. This is a completely different set of circumstances if you ask me.
