Lesson Topic: Run-On Sentences

Look at the following sentence.

     I saw a teacher who cares.

The author may have wanted to write

     I saw a teacher.  Who cares?

Using periods (and other forms of punctuation) and knowing when to end a sentence are very important.  If you don't end a sentence appropriately, the intended meaning can be changed, or it can be misunderstood.  Sometimes the meaning is simply incomprehensible. 

When a person learns to write English sentences and compositions, one common problem is writing sentences that are too longWhen a sentence ends too quickly, it is called a sentence fragment.  When a sentence has too many ideas and runs on too long, it is called a run-on sentence.  If you have this problem, don't worry.  It is quite easy to fix.

The first thing you need to do is identify when a sentence is a run-on.  A run-on (or run-on sentence) is a sentence that really has TWO sentences (or complete ideas) INCORRECTLY combined into one.  It is okay to combine two sentences into one, but you must follow some rules.  

You might be wondering: "What is a sentence?"  A sentence consists of 3 things:

1 subject the person, place, or thing performing or doing the action
2 verb the action
3 complete idea the reader isn't left waiting for another word

Take a look at this sentence:

I hit the ball.

Subject=I

Verb=hit

Is it a complete idea? Yes.

Therefore, this is a good sentence.

The ball is a direct object.  Not all sentences require a direct object.  For example

Birds fly.

Subject=birds

Verb=fly

Is it a complete idea? Yes.

There is no direct object here; however, it is still a complete idea and a good sentence.

Here's another example.

I take.

Subject=I

Verb=take

Is it a complete idea? No.

This sentence requires a direct object.  (This sentence is called a sentence fragment.)  It is actually the verb which determines whether the sentence requires a direct object or not.  If the sentence requires a direct object, it is called a transitive verb.  If the verb does not need a direct object, it is called an intransitive verb.  If you are unsure about some verbs, use a dictionary.  Dictionaries often denote transitive and intransitive verbs with the initials t.v. and i.v., respectively. 

Here's one more example.

Murray takes the train to school Mom rides the bus.

Subject=Murray AND Mom

Verb=takes AND rides

Is it a complete idea? It is TWO complete ideas.

This last example is a run-on sentence:  Two complete sentences (ideas) incorrectly combined.  This sentence lacks signal words which tell the reader when to stop or pause.  A part of a sentence that can be a sentence by itself is called an independent clause.  This last example has TWO independent clauses.

Summary

If you put two sentences (or independent clauses) together without a sufficient amount of signals (commas, semicolons, or connecting words), you have created a run-on. 

How do you fix run-ons?

There are four common ways to fix a run-on.  Each method is explained below.

Method #1

Write the two independent clauses as separate sentences using periods.

INCORRECT Carmen loved traveling in Italy she felt Rome was too hot.
CORRECT Carmen loved traveling in Italy.  She felt Rome was too hot.

Method #2

Use a semicolon to separate the two independent clauses.  If you would like to learn more about semicolons, click here.

INCORRECT Carmen loved traveling in Italy she felt Rome was too hot.
CORRECT Carmen loved traveling in Italy; she felt Rome was too hot.

Method #3

Use a comma and any one of the following connecting words:

for*      and      nor          but
or          yet          so**

*when for means because

**when so means as a result

 

INCORRECT Carmen loved traveling in Italy she felt Rome was too hot.
CORRECT Carmen loved traveling in Italy, but she felt Rome was too hot.

Method #4

Use a semicolon and one of the following words:

therefore,   thus,   however,  consequently,
furthermore,   also,   nevertheless,  

NOTE: If you use any of these connecting words with method #4, a comma must follow it.

INCORRECT Carmen loved traveling in Italy she felt Rome was too hot.
CORRECT Carmen loved traveling in Italy; however, she felt Rome was too hot.

NOTE: When using semicolons, the two independent clauses must share a related or common idea.  You cannot write the following sentence.

     Christine loves hot chocolate; I am watching TV.  

These two clauses are completely unrelated.

  Rules to Remember!

1 The above sentences are all examples of two independent clauses forming run-on sentences.  Sometimes three or more independent clauses are inappropriately written together, and the result is a very long run-on sentence.  We suggest that in these types of situations, use a combination of the above methods.  Take a look at the example below.

     Orville and Wilbur Wright had a bicycle-making business in Ohio they loved  experimenting with flying machines they built the Wright Flyer in 1903.

This sentence is a run-on with three independent clauses.  We can use various combinations of the above methods to fix the problem.  By applying methods 4 and 1, we get 

     Orville and Wilbur Wright had a bicycle-making business in Ohio; however, they loved experimenting with flying machines.  They built the Wright Flyer in 1903.

2

Don't string several independent clauses together with semicolons.  The following example is usually not written.

     Orville and Wilbur Wright had a bicycle-making business in Ohio; they loved  experimenting with flying machines; they built the Wright Flyer in 1903.

3 Some people may ask, "Which of the above methods is best?"  That answer is not so simple.  Sometimes any of the methods are equally correct; at other times, only one or two methods may truly be appropriate for a situation.  This knowledge will come as the writer reads a variety of English material.  

Also, don't overuse any one method.  Correctly using different methods often shows good writing.  When a person first learns to write, he/she uses method 1 extensively.  It is important for the writer to go beyond method 1 and use the other methods.  This will show a maturity in the author's writing.

4 We suggest that you also read our lesson on sentence fragments.
