§ 15.126. Commas.

 The following are guidelines for the use of commas:

   (1)  If a sentence consists of two independent clauses, each with subject and predicate, use a comma before the conjunction.

   (2)  If the second part of a sentence has no subject, a comma is unnecessary unless required for clarity.

   (3)  Enclose a parenthetical phrase or clause with two commas.

   (4)  Words, phrases, or clauses in a series are separated by commas.

   (5)  The use of the comma before the conjunction connecting the last two members of a series is preferable, but the comma may be omitted unless required for clarity.
