Expert writing Tips

Best practice

When indicating that something did not exist in the past, use the correct grammatical form "did not exist" or a suitable synonym such as "was not present".

Common error

Avoid using "was existed" or "was not existed". The correct form requires the auxiliary verb "did" to form the negative past tense: "did not exist".
