Clauses
A clause is a group of words that contains a subject and a predicate. Clauses are the building blocks of sentences and can be classified into two main types: independent clauses and dependent (or subordinate) clauses.
Independent Clauses
An independent clause expresses a complete thought and can stand alone as a sentence. It contains a subject and a verb, and it can function as a simple sentence by itself.
Examples:
- She enjoys reading.
- The dog barked loudly.
Dependent (Subordinate) Clauses
A dependent clause does not express a complete thought and cannot stand alone as a sentence. It needs to be connected to an independent clause to make sense. Dependent clauses often begin with subordinating conjunctions (e.g., because, although, since) or relative pronouns (e.g., who, which, that).
Examples:
- Because she enjoys reading (needs more information to be complete)
- When the dog barked loudly (needs more information to be complete)
Types of Dependent Clauses
- Adjective Clauses: Modify a noun or pronoun and usually begin with a relative pronoun (who, whom, whose, which, that) or a relative adverb (when, where, why).
Examples:
- The book that she borrowed from the library is fascinating.
- The student who studies the hardest usually scores the highest.
- Adverb Clauses: Modify a verb, adjective, or another adverb and begin with a subordinating conjunction (because, although, if, when, while, since, etc.).
Examples:
- Because it was raining, we canceled the picnic.
- Although she was tired, she finished her homework.
- Noun Clauses: Function as a noun within the sentence and can act as the subject, object, or complement. They often begin with words like that, what, whatever, who, whoever, whom, and whether.
Examples:
- What she said was surprising. (subject)
- She didn’t know that he was coming. (object)
- The important thing is that you are safe. (complement)
Combining Clauses
Clauses can be combined in various ways to form different types of sentences:
- Simple Sentence: Contains one independent clause.
- She enjoys reading.
- Compound Sentence: Contains two or more independent clauses, usually joined by a coordinating conjunction (for, and, nor, but, or, yet, so) or a semicolon.
- She enjoys reading, and she reads every day.
- The sun was setting; the sky turned orange.
- Complex Sentence: Contains one independent clause and one or more dependent clauses.
- She enjoys reading because it relaxes her.
- When the dog barked, she woke up.
- Compound-Complex Sentence: Contains at least two independent clauses and one or more dependent clauses.
- She enjoys reading because it relaxes her, and she reads every day.
- When the dog barked, she woke up, and she checked the time.
Punctuation with Clauses
- Independent Clauses:
- Use a comma before a coordinating conjunction joining two independent clauses.
- She enjoys reading, and she reads every day.
- Use a semicolon between two closely related independent clauses not joined by a conjunction.
- The sun was setting; the sky turned orange.
- Use a comma before a coordinating conjunction joining two independent clauses.
- Dependent Clauses:
- If the dependent clause comes before the independent clause, use a comma after the dependent clause.
- Because it was raining, we canceled the picnic.
- If the dependent clause follows the independent clause, no comma is needed (in most cases).
- We canceled the picnic because it was raining.
- If the dependent clause comes before the independent clause, use a comma after the dependent clause.
Understanding clauses and how to use them effectively allows for more complex and nuanced writing, enabling you to convey ideas clearly and accurately.
