Is it setup or set up?

It can be setup or set up depending on whether you’re using a compound noun or a phrasal verb.

“Set up” is a phrasal verb with multiple meanings, including these:

  • To build or assemble a structure (e.g., “We’ll set up the new Ikea desk tomorrow”)
  • To create a false impression that someone did something wrong (e.g., “George didn’t steal the answer key. Someone set him up”)

“Setup” is a noun with two possible meanings:

  • An arrangement of objects or details (e.g., “We have the perfect setup for overnight guests”)
  • The act of setting someone up for a crime or wrongdoing that they didn’t actually commit (e.g., “Bart didn’t pull the fire alarm. It was a setup”)
