Expert writing Tips
Best practice
Always ensure the phrase includes a verb, such as "is", "are", or "was", to form a grammatically correct relative clause (e.g., "which is relevant to").
Common error
Avoid omitting the verb "to be" (is, are, was, were) when using relative pronouns like "which" or "that". This omission leads to grammatically incorrect phrases that can confuse readers. Instead of "which relevant to", use "which is relevant to".
