Expert writing Tips

Best practice

Avoid using the phrase "contain of". Instead, use "contain" followed directly by the object, or use "consist of" to indicate composition.

Common error

A common mistake is adding the preposition "of" after "contain". Remember that "contain" directly takes the object it includes, while "consist" requires "of".
