Introductory Elements & Commas Worksheet

Introductory Elements

·         If a sentence does not being with the subject, it may open with an introductory element that tells when, where, how, or why the main action of the sentence occurs.  Separate that introductory element from the main part of the sentence with a comma. 

·         Use a comma following phrases that begin with if, when, although, because, and other subordinating conjunctions

·         Introductory prepositional phrases can be set off by commas if it is necessary for a clear understanding of the sentences meaning.

·         If the introductory element is short, and the sentence cannot be misread if the comma is omitted, you can omit the comma. 

EXERCISES

Underline each introductory element and punctuate the sentence with the appropriate commas.  Be careful to look also for other places in the sentence that require commas. (Hint:  Not all sentences have introductory phrases, and some are compound sentences.)
