Setup and Set Up Are Different Words

While setup and set up both refer to arrangements of some kind, they're not synonyms. In fact, they function quite differently in a sentence.

WordPart of SpeechDefinition
setupnoun or adjectivean arrangement
set upverbto make arrangements

If you're writing about an arranged situation, use setup. But if you're writing about the process of arranging that situation, use set up.

Setup Definition: An Arrangement

Setup refers to a situation that was previously arranged. It functions as a compound noun when it comes after an article (such as the or a), and it can also function as a compound adjective when it modifies another noun in the sentence.

How to Use Setup as a Noun

The noun function for setup can refer to any number of pre-arranged situations. It's a common term for a date that was arranged by someone else, the process of getting ready for an event, or getting an electronic device up and running.

  • The setup for your new game system is so complicated.
  • Mr. Turner insisted that the crime had been a setup.
  • We could use some help with the carnival setup.
  • I love the setup in your new apartment!

How to Use Setup as an Adjective

When you use setup as an adjective, it modifies another noun but still refers to a pre-arranged situation. For example:

  • Who's on the setup crew for the concert?
  • I can't read these setup instructions.
  • The setup shift at the restaurant gets all the tables ready for customers.
  • Follow the setup guide when your device starts for the first time.

What About Set-Up?

If setup looks like a typo, you may be used to the hyphenated version: set-up. This spelling is more common in British spelling, while setup is more common in American spelling. Neither way is incorrect as long as you're using it as a noun or adjective.

Set Up Meaning: To Make Arrangements

Set up is a phrasal verb that means "to arrange" or "to make arrangements." In other words, a person can set up a setup. Set is an irregular verb that is the same in both past and present tense and only changes in progressive tenses (setting).

  • Can you set up the birthday decorations now?
  • The suspect complained that he'd been set up by the police.

  • You did a lovely job setting the flower arrangements up.
