What Does PS Mean in a Letter? (Quick Scoop)

Basic meaning

  • PS stands for postscript , literally “written after.”
  • It’s a brief message added after the main body and closing of a letter or email.
  • People use it to add a forgotten detail, a friendly extra thought, or to highlight something important one last time.

Example:
Sincerely,
Maria PS: Don’t forget to bring your ID to the interview.

How and where to write PS

  • Place PS after your closing phrase and your name/signature, as the very last part of the message.
  • You can write it as PS: or P.S.: ; both forms are accepted, as long as you keep the style consistent.
  • Keep it short—usually one to two sentences, not a whole new letter.

Example:
Best regards,
Ahmed PS: I attached the updated schedule for next week.
