Expert writing Tips
Best practice
When asking if someone is "able", follow with a 'to + verb' construction to clarify what they're able to do, e.g., "Is he able to complete the project on time?"
Common error
Avoid using "is he able" when you actually want to know if someone is willing to do something. Ability refers to capability, while willingness refers to motivation. For example, instead of "Is he able to help?", consider "Is he willing to help?" if you're questioning his desire rather than his capacity.
