Expert writing Tips

Best practice

Avoid using double negatives like "did not neither". Instead, rephrase your sentence to use a single negative construction such as "neither did" or "did not either" for clarity and grammatical correctness.

Common error

Be careful not to combine negative words unnecessarily. Using "did not" with "neither" creates a double negative, which is grammatically incorrect and can confuse your readers. Stick to one negative element per clause.
