Run-together sentences (or run-on sentences) are examples of sentences that should be divided up into two sentences but have been written as if they are one sentence. Writing sentences like this is a common mistake.
Look at these two examples. Why do we describe them as run-together sentences?
- The corner-shop near us sells groceries and vegetables it also wells wine and beer.
- Jabu always prepares his lectures at the weekend he finds it easier that way.
They are described as run-together (or run-on) sentences because in fact they are both made up of two sentences. They should be divided up in the following ways:
- The corner-shop near us sells groceries and vegetables. It also wells wine and beer.
- Jabu always prepares his lectures at the weekend. He finds it easier that way.
We can correct run-together sentences in several different ways.
- We can use a semicolon if the sentences are not too long. We can also make two separate sentences.
- Jacob will start his new job in January; he's looking forward to it.
- The children love their new house; they play all the time in the garden.
- We can join sentences using a linking word like and, but, so, or, yet, for.
- Jacob will start his new job in January and he's looking forward to it.
- The children love their new house so they play all the time in the garden.
- Words such as because, although, since, so that, whereas can be used to begin a dependent clause that cannot stand alone.
- He was very tired and weary because it was a long way.
- Some countries have a long history of peace although this is not true of others.
- We can use a linking word or phrase (however, nevertheless, in addition, for example, on the other hand, moreover, therefore, consequently, in contrast) to make links between clauses/sentences.
- The area is very beautiful; however, it's also very remote.
- The government's tax policy needs reform; for example, inheritance tax.
- Her style on the dance-floor is faultless; in contrast, her private life is in chaos.
