Commas, Part 6
Rule – When starting a sentence with a weak clause, use a comma after it. (If the weak clause has three or fewer words, the comma is optional.) Conversely, do not use a comma when the sentence starts with a strong clause followed by a weak clause.
Examples:
If you are not sure about this, let me know now.
Let me know now if you are not sure about this.
On February 14 many couples give each other candy or flowers.
OR
On February 14, many couples give each other candy or flowers.
Rule – Use commas surrounding words such as therefore and however when they are used as interrupters.
Examples:
I would, therefore, like a response.
I would be happy, however, to volunteer for the Red Cross.
