predetermined

Predetermined means that something was decided or planned before, and it can't be changed now.

When we say that something is predetermined, we usually mean that someone has already thought about it, made a decision, and set things in motion. For example, if you were told what your Christmas gift would be beforehand, then the idea of getting that specific present was predetermined. It's like a plan had been made before, and now it's just going to happen as expected. In sports, a team might have a pre-determined strategy for a game, meaning they've thought about how they'll play ahead of time. The outcome is likely to be what the coaches wanted all along, because that was their predetermined goal.
