So... soog... she didn't answer that, so it'd be a part of speech... "and"? Yes taan, and hitao? Or "or". How does one... communicate logical operators?

Well, he could test one, and if she objects...

He'll need to teach "and" first, but that's probably easy. "Or" is the tricky one. He holds up a piece of chalk and says "chalk", and then a stick of gum and says "gum". Then he puts them down on the table next to each other, and says "Chalk and gum."
