Lesson 349

Mechanics - Punctuation - Commas

Use commas to separate a series of three or more phrases. Example: He ran down the hall, out the door, and into the yard. (The comma before the conjunctionA conjunction is a word that joins other words, phrases (groups of words), or clauses (groups of words with a subject and verb). Source: Lesson 77 and is optional, but I prefer using it.)

Use no commas in a series when all items are joined by or, and, or nor.

Instructions: Place commas where they are needed.
