1. Independent clause: An independent clause can stand alone as a sentence because it expresses a complete thought. It has a subject and a predicate. Example: "She went to the store."
2. Dependent clause: A dependent clause also has a subject and a predicate, but it is not a complete thought and cannot stand alone as a sentence. It relies on an independent clause to complete its meaning. Example: "Although she was tired..." (This clause does not express a complete thought until combined with an independent clause, such as "Although she was tired, she went to the store.")
3. Adjective clause: An adjective clause functions as an adjective by modifying a noun or pronoun in a sentence. It begins with a relative pronoun like "who," "whom," "which," "that," or a relative adverb like "where," "when," or "why." Example: "The man who is wearing a hat is my neighbor."
4. Adverb clause: An adverb clause functions as an adverb by modifying a verb, adjective, or adverb in a sentence. It answers questions like how, when, where, why, or to what extent. Example: "She studied hard because she wanted to pass the exam."
5. Noun clause: A noun clause works as a noun in a sentence. It can function as the subject, object, or complement. Example: "What he said shocked everyone." (Here, "What he said" acts as the subject of the sentence.)
These are just a few examples of different types of clauses. Understanding clauses is an essential aspect of grammar, as they help to form complete sentences and convey precise meaning.
