Expert writing Tips

Best practice

Always use the correct past tense conjugation. Instead of "did not be", use "was not" or "did not" followed by a verb.

Common error

Avoid using "be" after "did not". "Did" is an auxiliary verb that requires the base form of a verb, so using "did not be" creates an ungrammatical construction.
