Coordinating Conjunctions
You can also fix run-on sentences by adding a comma and a coordinating conjunction. A coordinating conjunction acts as a link between two independent clauses.
Adding dependent words is another way to link independent clauses. Like the coordinating conjunctions, dependent words show a relationship between two independent clauses.
Run-on: We took the elevator, the others still got there before us.
Complete sentence: Although we took the elevator, the others got there before us.
Run-on: Cobwebs covered the furniture, the room hadn’t been used in years.
Complete sentence: Cobwebs covered the furniture because the room hadn’t been used in years.
Figure 1.4 Sample e-mail
Isabelle’s e-mail opens with two fragments and two run-on sentences containing comma splices. The e-mail ends with another fragment. What effect would this e-mail have on Mr. Blankenship or other readers? Mr. Blankenship or other readers may not think highly of Isaebelle’s communication skills or—worse—may not understand the message at all! Communications written in precise, complete sentences are not only more professional but also easier to understand. Before you hit the “send” button, read your e-mail carefully to make sure that the sentences are complete, are not run together, and are correctly punctuated.
