Expert writing Tips

Best practice

Use "which I" to add non-essential, descriptive information to a sentence. Remember to separate the clause with commas if it's non-restrictive.

Common error

Avoid using "that I" when "which I" is more appropriate. "Which I" is often used for non-restrictive clauses that add extra information, while "that I" is used for restrictive clauses that are essential to the sentence's meaning.
