Expert writing Tips

Best practice

Always use "which contains" or "which consists of" instead of "which contains of". Ensure the verb "contain" is followed directly by the object it contains, without the preposition "of".

Common error

Avoid using "contains of". The correct form is "contains". For example, say "The box contains books" not "The box contains of books".
