The Origin of Followup or Follow Up

The phrase comes from the verb follow + the preposition up, meaning “to continue or check again.” Over time, English turned the phrase into a compound noun/adjective (follow-up) to describe the action or result.

This pattern exists in many English words:

• check in → check-in
  
• sign up → sign-up
  
• back up → backup
