In this part you will be dealing with conjunctions. They are used to combine two sentences into one — a compound sentence. Some conjunctions have an adverbial usage, but here you will encounter them as they are used in everyday language: as words that combine two phrases or sentences into one. 

  • If the combined sentences each have a subject and a verb, separate the sentences with a comma: 

John is a doctor, and Mary is a lawyer. 

John is a doctor and works in Chicago. 

  • If the combined sentences begin with a conjunction, separate them with a comma: 

If you work hard, you can have a good life. 

When using however or therefore, you should separate the combined sentences with a semicolon: 

His hands were tied; however, he continued to struggle to get free. 

There’s a storm coming; therefore we have to stay alert. 

The use of the comma is optional when the two parts of the sentence are related or are linked by meaning: 

Alicia is smart, but she hates to study. 

Alicia is smart but she hates to study. 

  • Following are some commonly used conjunctions: 









  • Look at the following examples: 

There was nothing the doctor could do; therefore he left. 

Anna is a smart girl, but she just doesn’t like studying. 

Because she became ill, Maria couldn’t go to the party. 

Interrogative pronouns

Interrogative pronouns, which ask a question, can also be used as conjunctions. They are not true conjunctions, but they can still be used to combine two sentences into one.

  • These are interrogative pronouns: 






  • Look at these examples: 

I don’t know why you have to go so early. 

Can you tell me how I can find Green Street? 

When John came into the room, she began to blush.
