Expert writing Tips
Best practice
When using "is up to", clearly define who or what is being referred to, avoiding ambiguity. For example, instead of saying "It is up to them", specify "The decision is up to the shareholders".
Common error
Avoid assuming that "is up to" implies absolute authority or capability. Sometimes, even when someone has the responsibility, they might lack the resources or support needed to fulfill it. For instance, saying "Change "is up to Pakistanis themselves"" doesn't negate the need for external aid or structural reforms.
