Expert writing Tips

Best practice

Always use the correct auxiliary verb ('have') with 'written' to form the present perfect tense (e.g., "I have written on").

Common error

Avoid using the past participle 'written' without the auxiliary verb 'have' when you mean to say you have previously written something. The correct phrase is "I have written on", not "I written on".
