Expert writing Tips

Best practice

When expressing inability, ensure that the correct form of the verb "to be" is used, such as "is", "are", "was", or "were", depending on the subject and tense.

Common error

A common mistake is using the wrong form of the verb "to be" after "could not". Remember to use "be" as the base form after modal verbs like "could". For example, say "they could not be reached", not "they could not are reached".
