1. THE SEMICOLON How do you use it?
The semicolon is one of three ways that you can put two complete sentences back to back.

2. As a rule. . . Semicolons connect 2 COMPLETE sentences.
This means for two sentences to be back to back, each must contain a subject, verb and a complete thought.
It would look like this:
Subject+verb & complete thought ; subject+verb & complete thought
My dog likes water; he jumps in the pond every day.
NOT
My dog likes water;jumps in the pond every day. (notice that the 2nd half is not a complete sentence!

3. Special circumstances that you need to watch out for:
I worked at Burger King; while I was a student at NC State.
THIS IS WRONG!
Notice how the semicolon separates two thoughts but not two complete sentences.
The clause after the semicolon is not a complete sentence because it does not complete a thought.

4. Things to watch out for #2:
Watch out for conjunctive adverbs.
I am nervous, therefore; I might be sick.
This is WRONG!
Notice how the semicolon is put in the wrong place.
“Therefore”—your conjunctive adverb or transition word—goes with the 2nd sentence, not the first, so the semicolon should go BEFORE the conjunctive adverb or transition word.

5. Conjunctive Adverbs
When you are learning about semicolons, you are going to hear the word “conjunctive adverb.”
A conjunctive adverb is a word that helps transition ideas. Notice the key word here, “ideas.” Notice that I didn’t say connects “complete sentences.”
Since a conjunctive adverb can’t connect 2 sentences, if it comes between 2 sentences, there must also be a period or semicolon.
EX: Dogs are lazy; therefore, they sleep all day. CORRECT!
EX: Dogs are lazy, therefore, they sleep all day—WRONG!
Notice in the “wrong” example that a comma is not strong enough to connect two sentences, so even when a conjunctive adverb is added between two sentences, a comma is still not strong enough!
A period or semicolon must come between the two sentences.

6. COMMON Conjunctive Adverbs
There is no way to memorize ALL of the conjunctive adverbs, but if you become familiar with the most common ones, it will help you to recognize them in sentences and use them in your writing.
Examples:
However
Moreover
Therefore
Also
In addition
Additionally
Consequently

7. Things to watch out for #3
I will have to try harder in my English class; or I will fail.
WRONG!
If you see the words for, and, nor, but, or, yet, so (words that we will call fanboys), they can come between 2 completed sentences, but a comma always comes before them, not a semicolon.
