Expert writing Tips

Best practice

Always use the correct grammatical form, which is "about to leave", when indicating an imminent departure or action. For example, use "I am about to leave" instead of "I am about to leaving".

Common error

Avoid using the gerund form ("leaving") after "to" when it functions as part of the "about to" construction. "About to" requires the base form of the verb, not the -ing form. Therefore, always use "leave" instead of "leaving".
