An adjective clause is a type of dependent clause that acts as an adjective in a sentence by modifying a noun or pronoun. Adjective clauses are also known as relative clauses because they begin with a relative pronoun, such as "who," "whose," "whom," "that," or "which."
For example:
The woman who works at the store is my neighbor.
In this sentence, the adjective clause "who works at the store" modifies the noun "woman" and tells us more about her.
An adverb clause, on the other hand, is a type of dependent clause that acts as an adverb in a sentence by modifying a verb, adjective, or adverb. Adverb clauses are also known as subordinate clauses because they depend on the main clause to make sense.
For example:
I will eat dinner after I finish my homework.
In this sentence, the adverb clause "after I finish my homework" modifies the verb "eat" and tells us when the action of eating dinner will take place.
It is important to note that both adjective clauses and adverb clauses must be connected to the main clause in a sentence with a subordinating conjunction, such as "after," "although," "because," "before," "since," "that," "when," "where," or "while."
In conclusion, adjective clauses and adverb clauses are both types of dependent clauses that add additional information to a sentence by modifying a noun or pronoun (adjective clause) or a verb, adjective, or adverb (adverb clause). Both types of clauses must be connected to the main clause with a subordinating conjunction. Proper usage of adjective and adverb clauses can add depth and clarity to written and spoken communication.
