Let's define these types of clauses. Adjective clauses can serve as a multi-word adjective, basically. Noun clauses can serve as a multi-word noun, with a subject and verb, but remember, they are still dependent. Adverb clauses start with a subordinating conjunction. Now let's dissect this sentence.
