“Let’s make an AGREEMENT. You wash the dishes, and I’ll dry them.”
“If you clean your room, you can have dessert. Okay? Do we have a DEAL?”
“You’re breaking our ARRANGEMENT! I lead the horse to water, but now you’re not making him drink!”
In this context, would it be appropriate to use the sign CONTRACT? I keep finding “AGREE” online; as in “THINK-SAME.” But that doesn’t feel conceptually accurate.
