By the end, you will know when to write checkout and when to write check out. No guessing. No stress. Just clear, correct writing that helps you look professional in emails, on websites, and in school or work papers.

Checkout or Check Out Quick Answer

Here is the short rule.

• Checkout (one word) is a noun or an adjective. It names a thing or describes one.
• Check out (two words) is a verb. It is an action.

A good test: can you put “the” or “a” before it? If yes, use checkout. If you can change the tense (checked out, checking out), use check out.

Checkout examples (one word):

• Please go to the checkout.
• The checkout page is slow.
• I waited in the checkout line.

Check out examples (two words):

• We check out at 11 a.m.
• Check out this new video.
• She will check out two books from the library.

The Origin of Checkout and Check Out

The word “check” has an old story. It comes from the game of chess. In old Persian, shah meant king. When you attacked the king, players said “check.” The word moved through Old French and into English.

Over time, “check” took on new meanings. It came to mean stop, test, or control. It also came to mean a mark that shows something was counted or approved.

That is where “check out” comes from. People used it for a kind of control. You checked a book out of a library. You checked out of a hotel. In both cases, you signed off and left with something or left a place.

Then shops changed. Stores began to use a spot where you pay and leave. People called it the checkout. The verb phrase turned into a single noun. This is a common pattern in English. Many two-word verbs become one-word nouns:

• log in (verb) → login (noun)
• back up (verb) → backup (noun)
• set up (verb) → setup (noun)
• check out (verb) → checkout (noun)

So the spelling difference is not random. It follows a rule. The verb has a space. The noun does not.

British English vs American English Spelling

Here is the surprise. This is not a true US versus UK spelling difference.

Most spelling gaps between the two (like color and colour) are about letters. This one is about grammar. Both American and British writers use the same rule. Noun is one word. Verb is two words.

There is one small note. Older British writing sometimes used a hyphen, as in “check-out.” Some UK writers still do this for the noun or for the hotel meaning. Modern dictionaries and most style guides prefer “checkout” for the noun and “check out” for the verb. You will see the hyphen less and less.

Use	American English	British English	Part of speech
Place to pay in a store	checkout	checkout (older: check-out)	Noun
Online payment step	checkout	checkout	Noun
Checkout counter	checkout counter	checkout counter (also “till” is common in the UK)	Adjective + noun
Leave a hotel	check out	check out	Verb
Look at something	check out	check out	Verb
Borrow a library book	check out	check out (UK also says “borrow”)	Verb

Tip: in the UK, people often say “till” or “the tills” for the place to pay in a shop. They still say “checkout” online.

Which Spelling Should You Use?

The answer depends on the job of the word, not on where you live. But your audience still matters a little.

If your readers are in the US: Use “checkout” for the noun and “check out” for the verb. This is the standard.

If your readers are in the UK or the Commonwealth: Use the same rule. You may see “check-out” in older books or news. For new writing, skip the hyphen.

If your readers are worldwide: Use the same rule. It is the safest choice. Online stores, apps, and big brands all use “checkout” for the page and “check out” for the action.

Simple choice guide:

• Naming the page, button, line, or counter? Write checkout.
• Telling someone to do something? Write check out.
• Describing a thing with it, like “checkout process”? Write checkout.
