When beginning a sentence with "well", do you put a comma after it?

  • Well, you know I was wrong.
  • Well you know I was wrong.

Best Answer

Well water does not contain chlorine. In the previous sentence the word in question is used to modify the subject of the sentence, water. But, when well is an expletive, it is parenthetical and needs the comma.
