First, stop that run-on!

Let´s Revise

   A run-on sentence is a sentence in which two or more independent  clauses (i.e., complete sentences) are joined without appropriate punctuation or conjunction.

  An example of a run-on is a comma splice, in which two independent clauses are joined with a comma without an accompanying coordinating conjunction

          Take a look at these cases:

Ø  A run-on sentence, without any punctuation or conjunction between "gas" and "we":

                       My car is out of gas we cannot reach town before dark.

Ø  A comma splice, which is considered a run-on sentence in English by some usage experts:

It is nearly half past five, we cannot reach town before dark.

           These are possible remedies:

• Use separate sentences. However, this may disconnect related independent clauses and cause some of the meaning to be lost:
• It is nearly half past five. We cannot reach town before dark.
• Use a semicolon. This maintains the connection between the clauses while ensuring a pause between the two ideas:
• It is nearly half past five; we cannot reach town before dark.
• Use a coordinating conjunction.
• It is nearly half past five, so we cannot reach town before dark.
