Usage notes 
- (choice or judgment): Most often, to decide something is to make a decision; however, other possibilities exist as well. Many verbs used with destination or conclusion, such as reach, come to, and arrive at can also be used with decision; these serve to emphasize that the decision is the result of deliberation. Finally, some varieties of English prefer to take a decision rather than make one.
