Commas Following Introductory Words, Phrases, and Clauses

Use a comma to set off introductory words, phrases, and clauses from the main part of a sentence. The comma keeps a reader from accidentally attaching the introductory portion to the main part of the sentence and having to go back and reread the sentence. In other words, commas following introductory elements will save the reader time and reduce the chances of misinterpreting what you write. Examine the examples below to see how introductory words, phrases, and clauses are set off with commas.


Words:

Disappointed, we left the movie before it ended.

Annoyed, the manager stomped back into the storeroom.

Amazed, Captain Holland dismissed the rest of the troops.


Phrases:

Expecting the worst, we liquidated most of our inventory.

Badly injured in the accident, the president was gone for two months.

Reluctant to make matters any worse, the doctor called in a specialist.




Clauses:

If we plan carefully for the grand opening, we can increase sales.


While we were eating lunch, an important fax came.


Because we left before the meeting ended, we were not eligible to win a door prize.


One part of it dealt with subordinate or dependent clauses. Subordinate or dependent clauses are what you see in the last set of examples above. The first part of each sentence, the subordinate or dependent clause, is followed by a comma. The two parts of each of these sentences could very easily be reversed and the sentence would still make sense. However, if you reverse the sentence parts, making the independent clause the first clause in the sentence, you would NOT need a comma.


Subordinate clauses after the independent clause:

We can increase sales if we plan carefully for the grand opening.

An important fax came while we were eating lunch.

We were not eligible to win a door prize because we left before the meeting ended.
