Conjunctions

A simple sentence is an independent clause.  A conjunction is used to join two independent clauses and make them a compound sentence.  A compound sentence is longer than a simple sentence, and a complex sentence has more supporting information than a simple sentence.  In a complex sentence, when two sentences are joined together, one becomes a dependent clause. A dependent clause is marked as either an [adjective] or {adverb}.  The independent clause is marked as a sentence. 

1. A compound sentence is two or more independent clauses joined together. 

Examples:             

(Dependent) A [large] crowd .gathered. /outside/, and the march .began.

(Independent) A [large] crowd .gathered. /outside/. The march .began.

2.  An independent clause contains a verb and subject and expresses a complete thought. It can also be set off from the rest of the sentence with commas. 

Example:

(Independent) A [large] crowd .gathered. /outside/,

(Dependent): and the march .began.

(Dependent) I .washed. the /dishes/, and she .cleaned. the /floor/, but

no one .made. /lunch/.

(Independent) I .washed. the /dishes/. She .cleaned. the /floor/.

No one .made. /lunch/. 

3. Use conjunctions to join only clauses that are closely related in thought.

Good: Mary went to the movies, but I could not go.

Not good: Mary went to the movies, but I like milk.

4. A compound sentence can be divided into two sentences (or two independent clauses):

Examples:

Shirley cleaned the house, and I watched the children.

Shirley cleaned the house.  I watched the children.

5. A simple sentence cannot be divided into two independent clauses that make sense, even if it has compound parts:

Good: A man in a blue suit went by and crossed the street.

Not good: A man in a blue suit went by.  Crossed the street. 

6. The conjunctions and, but, and or are used most often in compound sentences.  These coordinating conjunction join words, phrases, or clauses of equal value. 

Examples:

You and I work together. 

He came early, but he did not stay late. 

Are you in or out?

7. When a coordinating conjunction joins clauses, it is not part of the clause itself. However, it may be included in the clause’s markings. 

Example: We .must learn. {to read}, {and we must learn to spell}. 

8. Some very short clauses that are closely related to each other, may not have commas between them.

Example: He .has. the /tickets/ and I .have. the /transportation/.
