Expert writing Tips

Best practice

When using "which are used", ensure the clause provides essential information, or use "that are used" if the clause is restrictive and critical to the sentence's meaning.

Common error

Avoid substituting "where" for "which" when referring to objects or concepts. "Where" should only be used to refer to places. For instance, the correct usage is "tools which are used", not "tools where are used".
