should comma go after is
One of the most frequent errors in comma usage is the placement of a comma after a coordinating conjunction. We cannot say that the comma will always come before the conjunction and never after, but it would be a rare event, indeed, that we need to follow a coordinating conjunction with a comma.When speaking, we do sometimes pause after the little conjunction, but there is seldom a good reason to put a comma there.t is permissible to omit the comma after a brief introductory element if the omission does not result in confusion or hesitancy in reading. If there is ever any doubt, use the comma, as it is always correct. If you would like some additional guidelines on using a comma after introductory elements, click HERE.
