1. Adverbial dependent clauses: These clauses function as adverbs and provide information about time, place, manner, condition, purpose, or reason. For example, "After I finish my work, I will go for a walk." In this sentence, the dependent clause "After I finish my work" acts as an adverb, indicating when the speaker will go for a walk.
2. Adjectival dependent clauses: These clauses function as adjectives and modify nouns or pronouns. They provide additional information about the noun or pronoun they are modifying. For example, "The book that I borrowed from the library is very interesting." In this sentence, the dependent clause "that I borrowed from the library" modifies the noun "book" and provides information about which book is being referred to.
3. Noun dependent clauses: These clauses function as nouns and can act as subjects, objects, or complements in a sentence. For example, "What she said surprised me." In this sentence, the dependent clause "What she said" acts as the subject of the sentence, replacing a noun. It functions as a noun because it is the thing that surprised the speaker.
