The phrase "up to someone" is an idiom that refers to the responsibility, decision-making power, or prerogative that an individual possesses regarding a particular matter or situation. It implies that the individual in question has the authority or control over a specific action, choice, or outcome.
When something is "up to someone," it means that the ultimate decision or course of action rests entirely with them. They have the autonomy and freedom to determine what should be done, how it should be done, or the direction to be taken.
This expression is often used to relinquish accountability, establish personal choice, or highlight individual agency. It recognizes and respects an individual's ability and right to decide, select, or assume responsibility for a given situation.
For instance, if a supervisor says, "It's up to you how you complete this project," they are granting the employee the authority to choose the methods and approach to meet the project requirements. In this case, the decision-making power lies in the hands of the employee.
The phrase can also imply that someone has the potential or capacity to fulfill a particular role or expectation. For example, if someone says, "The success of this event is up to you," it means that they believe in the person's capabilities and hold them responsible for ensuring the event's success.
In summary, "up to someone" signifies an individual's authority, responsibility, or freedom to make decisions, take charge, or achieve a certain outcome in a given context.
