Expert writing Tips

Best practice

Always use the correct past participle form "collaborated" after "had". This ensures grammatical accuracy and clarity in your writing.

Common error

Avoid using the present participle "collaborating" directly after "had". The correct form is the past participle, which is "collaborated". Using the present participle creates a grammatically incorrect phrase.
