Adjective clauses An adjective clause adds more information about a noun by using a clause with a relative pronoun, such as ‘who’, ‘whom’, ‘which’, ‘that’ or ‘whose’. The adjective clause follows the noun. This might sound tricky but is actually quite easy. Here is an example: The boy who was sitting in the park had just lost his football. The words underlined are the adjectival clause. Notice that without this clause the sentence would still make sense:      The boy had just lost his football.
