Expert writing Tips
Best practice
When using "which are written", ensure the 'which' clause refers to a non-restrictive clause, adding extra information that isn't essential to the sentence's meaning. If the information is essential, use 'that are written' instead.
Common error
Avoid using "which are written" in restrictive clauses, where the information is essential for identifying the noun. In such cases, "that are written" is more appropriate. For example, instead of "The books, which are written in English, are popular", use "The books that are written in English are popular" if only the English books are popular.
