Other forms: decisions
A decision is a settled judgement about what to do. Make a decision, a difficult decision, the decision stands.
The settling is the point: a decision closes a question, which is why decision fatigue — the falling quality of choices as the day goes on — is a real and measured effect. In sport, a decision is the referee's call. In boxing, winning on a decision means on points. Note decisive; and that the Latin means cutting off, from caedere, which also gives scissors.
