Setup or Set Up: Quick Answer

Setup (one word) is a noun or adjective. It refers to a configuration, arrangement, or preparation.
Set up (two words) is a verb phrase. It describes the action of arranging, organizing, or preparing something.

Examples:

The computer setup was complicated.
I need to set up my new laptop.

Quick trick:

If you can replace it with arrangement, preparation, or configuration, use setup.
If you are describing the action of doing something, use set up.

The Origin of Setup or Set Up

The words come from the verb set, meaning “to place” or “to put in position,” combined with up, meaning “upright” or “in order.”

Over time:

When used as a verb, it stayed two words: set up.
When used as a thing or description, writers started merging it: setup.

This evolution is common in English. Many phrasal verbs become single words when they start functioning as nouns or adjectives (for example, “breakdown” from “break down”).
