Deciding is making up your mind about what to do or choose.
When we decide something, it means that we've thought about all the options and made a choice. You might be deciding whether to go to the movies tonight or stay home and watch TV. Your friend might be deciding which college to attend next year. It's like weighing the pros and cons and finally saying "yes" to one thing instead of another. Sometimes, it can be hard to decide because we're not sure what's best for us, but in general, making a decision is about picking the option that feels right at the moment.
To resolve (a contest, problem, dispute, etc.); to choose, determine, or settle
