Here's a breakdown of what a subordinate clause can do:
1. Provide additional information:
* Adjective clauses: They modify nouns or pronouns, telling us more about them.
* *Example:* "The book that I borrowed from the library is very interesting." ("that I borrowed from the library" modifies "book")
* Adverb clauses: They modify verbs, adjectives, or other adverbs, telling us when, where, why, how, or to what extent something happened.
* *Example:* "When I finish my work, I will go to the movies." ("When I finish my work" modifies "will go")
2. Act as a noun:
* Noun clauses: They function as the subject, object, or complement of a sentence.
* *Example:* "What you said surprised me." ("What you said" is the subject of the sentence)
3. Express a variety of relationships:
* Time: "Before I left, I turned off the lights."
* Place: "Where the river flows, the land is fertile."
* Cause: "Because it was raining, we stayed inside."
* Contrast: "Although she was tired, she continued working."
* Condition: "If you study hard, you will succeed."
Key Features:
* Subordinating conjunction: Subordinate clauses typically begin with a subordinating conjunction (e.g., because, although, while, when, if, that, who, which).
* Incomplete thought: They express a partial thought that requires an independent clause to make sense.
In summary, subordinate clauses provide extra information, act as nouns, and express various relationships within a sentence, all while relying on an independent clause to form a complete thought.
