grammar week 2

Like most people I don't write a sentence then stop and read the sentence to make sure it is not a run on sentence. A run on sentence is the combination of two or more complete thoughts without the proper punctuation between them.

Step 1
There are two types of run-on sentences. The first occurs when two main clauses are joined by a comma only. This is called a ‘comma splice’. e.g. Meteorology is fascinating to me, I watch the Weather Channel every day.
Step 2
The second type of run-on sentence occurs when two main clauses have no punctuation separating them. This can occur with or without a conjunction. e.g. Meteorology is fascinating to me I watch the Weather Channel every day. e.g. Meteorology is fascinating to me and I watch the Weather Channel every day.
Step 3
You can correct a run-on sentence in several ways. The method you choose in correcting your writing will depend on the relationship you want top convey between the two clauses.
Step 4
One method is to add end punctuation between the clauses and make two sentences. [Meteorology is fascinating to me, I watch the Weather Channel every day.] Another way is to separate the clauses with both a comma and a coordinating conjunction. [Meteorology is fascinating to me, and I watch the Weather Channel every day.]
Step 5
Alternatively you can add a semicolon and a conjunctive adverb between the clauses. [Meteorology is fascinating to me; I watch the Weather Channel every day.] You can change one of the main clauses to a subordinate clause. Separate the two clauses with a comma if appropriate. [Because meteorology is fascinating to me, I watch the Weather Channel every day.]
