Punctuation: Punctuation Matters

Punctuation Matters

The following two letters contain the same exact words—but the punctuation differs sharply. Which letter would you rather receive?

  • Dear John:
  • I want a man who knows what love is all about. You are generous, kind, thoughtful. People who are not like you admit to being useless and inferior. You have ruined me for other men. I yearn for you. I have no feelings whatsoever when we're apart. I can forever be happy—will you let me be yours?
  • Harriet
  • Dear John:
  • I want a man who knows what love is. All about you are generous, kind, thoughtful people, who are not like you. Admit to being useless and inferior. You have ruined me. For other men, I yearn. For you, I have no feelings whatsoever. When we're apart, I can forever be happy. Will you let me be?
  • Yours,
  • Harriet

These letters tell us a lot about John and Harriet—but they tell us even more about the importance of punctuation. Change a comma here, move a period there … and the entire document is different. That's why punctuation matters; it creates meaning as much as words do.
