connecting sentences: conjunctions


There is only one verb in a simple sentence. If you want to join two simple sentences to form a compound sentence, you use a conjunction. Remember, you can never use two  verbs in a simple sentence.

e.g. I like ice-cream.          
                                         Two simple sentences.
   Mary hates ice-cream.       

   I like ice-cream but Mary hates it.        One compound sentence

You can use the conjunction but as a bridge to connect the two clauses (independent clauses) of the compound sentence.

I like ice-cream. ---simple sentence

I like ice-cream but Mary hates ice-cream. -----compound sentence

I like ice-cream, ---------clause

but Mary hates ice-cream----------clause

In a sentence with one conjunction, you can use two verbs.

Other conjunctions are:
and, or, because, but, although, so, if, not only..but also, since, as

e.g. Although John is my best friend, I will punish him.
   I must attend Johns wedding because he is my best friend.

Remember that when you have used although, you should not use but in the same sentence.

Similarly, when you have used because, you should not use so in the same sentence.

In summary
S1V1O1 + conjunction + S2V2O2
