DD is an acronym for Dear Daughter or Darling Daughter. DD is most often used by a parent as a form of affection and identification of their child. Likewise, DS is an acronym for Dear Son, which is used in the same context.

DD is commonly used in forms of digital communication, such as chat rooms, instant messaging, text messaging, email, and other real-time, text-based communications. Like most messaging abbreviations, it is best to use DD in casual conversations between family and friends. For the sake of clarity, it’s better to avoid using DD in professional communications.

Examples of DD used in a sentence are as follows:

  • “I have to go pick up my DD from school.”
  • “DD and I are going to dinner tomorrow night.”
  • “Have you seen my DD’s grades this semester? She’s gotten high marks in every class!”
