BizWritingTip reader: “I am confused about the punctuation with the word ‘however.’ I know that I must always place a comma after it. But when do I use a comma before it and when do I use a period?”
BizWritingTip response: Most people do not know how to punctuate the word “however.” If you understand this point, you will be the grammar guru of your office. The problem occurs because sometimes the word is used as an interrupting word within a sentence and, at other times, it is used to connect two sentences.
