What’s the Difference Between Checkout and Check Out?

These two terms sound alike other than the short pause between the words in check out. However, they cannot be interchanged since they don’t have the same part of speech.

Checkout can act as either an adjective or noun. It refers to the process of leaving a hotel or paying for the items you went shopping for at a register.

• The checkout line at the grocery store is longer than usual today.

Check out is a phrasal verb with the same meaning as checkout. It can also mean to examine something interesting or to look at a person in a way meant to show attraction.

• Check out this inconsistency in the data.

Let’s practice a few ways you can use these terms in your sentences to help you avoid mixing them up.

Using Checkout in a Sentence

When to use checkout: Checkout can be either a noun or adjective referring to leaving a hotel after a stay is complete, or paying for purchases.

For example,

• Welcome to the hotel! Checkout time is at 11 o’clock.
• At the checkout, she realized she had forgotten to buy blueberries.

The noun form originated in the 1940’s, and came from the phrasal verb.

Using Check Out in a Sentence

When to use check out: Check out is a phrasal verb that shows the action form of the noun, with the same meaning. Additionally it can mean to look at something carefully or look at something new. One of the slang meanings means show sexual or romantic interest in someone else by looking at them.

For example:

• I can help you check out over at register 2. (allow a customer to pay for purchases)
• Check out the new sculpture I made! Pretty cool, right? (look at something new)
• They went to the beach to check out all of the cuties swimming. (looking to show attraction – informal)

Another slang usage of this phrasal verb means to die or to stop paying attention.

Remembering Checkout vs. Check Out

The best way to remember the difference between these two terms is to think of the part of speech for each. Checkout is a noun, and like most other nouns, it is only a single word. Check out is a phrasal verb, and like most other phrasal verbs it is two words.

To help you remember this think of the third person form. She always checks out the same library book. The use of s at the end of checks wouldn’t be possible if the verb was one word. The progressive form, she is checking out can also help you remember that the verb should have two separate words.

Outside Examples

• Authorities say a woman tried to sneak more than $1,800 worth of electronics through a Florida Walmart’s self-checkout by switching the items’ price tags with those from clearance items. –Chicago Sun Times
• Don’t be afraid to ask for that which is not overtly promoted. Case in point: Lane Bryant gives extra discounts to teachers who show a valid school ID or pay stub during checkout. –Chicago Tribune
• Shoppers check out the wares at Macy’s. –New York Daily News
• Meanwhile, check out this theory, posited in this BuzzFeed article, that people who speed up their podcasts (”podfasters”) may be more likely to pay attention to the ads contained within because they’re less likely to skip commercial breaks and higher-pitch sounds are easier to hear. –Wall Street Journal

Check out

Check out is a phrasal verb of the word check, which has 2 meanings:

• to look at someone/something
• to sign for something (like a will)

You can also add a noun or pronoun between the words, like ‘check this out’, ‘check the items out’ etc.

Example usage:

• I am going to check out the place tomorrow. (I am going to see/explore the place)
• Let’s check out the movie tickets for Saturday evening.
• Hey, check this game out, it’s so entertaining and engaging.
• I tried to check out the item from my cart, but looks like there is a technical issue.  (Notice that we don’t use checkout here, because here check out indicates an action (verb))

Sometimes, check out is used with a hyphen i.e. check-out. This is not a very correct usage and should be avoided.

Checkout

Checkout is used as a noun or adjective. It is used to indicate a departure from a place, like a line at the grocery store, or a hotel. Examples:

• The checkout is at 12pm every day.
• There is such a big line for the checkout today!
• The checkout date for these books is tomorrow, so finish reading them fast.

The main point to remember is the part of the speech of each word:

• checkout – noun/adjective
• check out – verb

Read the below sentences carefully:

• We will check out from the hotel at 12pm.
• The checkout time at the hotel is 12pm.

The meanings are same; however, the describing word is different. In the first sentence, check out is a verb i.e. the action in the sentence is ‘checking out’. However, the second sentence has modal verb ‘is’, and there is no other verb. It is a general statement and not particularly referring to any action.

Another example,

• The apples I checked out from your shop weren’t verified for quality.
• The checkout process wasn’t properly followed at your shop.

Remember to use check out with the space when checking out is the action, else use checkout without the spaces.

Q: This is probably too hair-splitting for your blog. BUT! At my local library, one takes out a book by touching “check-out” on a kiosk screen. Something as un-world-shaking as a hyphen is probably dwarfed by concerns like global warming, but for heaven’s sake it’s the library, one of the leaders of literacy. Shouldn’t this read either “checkout” or “check out”?

A: We consider no hair too tiny to split. This is the usual way “check” and “out” come together, according to the 10 standard American and British dictionaries we’ve consulted.

The phrasal verb is “check out,” two words. The noun and adjective are both “checkout,” one word. Nary a hyphen among them.

Although a few of the dictionaries list hyphenated versions of the verb, noun, or adjective as variants, we think the library should alter that screen.

If the verb is intended, then the screen should read “Check Out,”  as if the instruction were short for “Check Out Here.”

If the adjective is intended, the screen should read “Checkout”—as if short for “Checkout Option.”

And if the noun is intended, the screen should also read “Checkout”—as if short for “Book Checkout.”

Over time, as we’ve written before on our blog, hyphens tend to disappear from familiar compounds. This is especially true in the case of nouns and adjectives.

The early 20th-century formations that started out as “teen ager” and “teen age” are good examples. These two-word formations later gained hyphens (“teen-ager,” “teen-age”), but eventually the hyphens disappeared (“teenager,” “teenage”).

The Oxford English Dictionary, an etymological dictionary based on historical evidence, shows that the verb “check out” has almost always been written that way—two words, no hyphen. Similar phrasal verbs include “check off,” “check over,” “check on,” “check up,” and “check up on.”

Since it first appeared in the early 1920s, the verb has had various meanings. Someone can “check out” at a hotel or store, “check out” (inspect or test) a new car, “check out” (investigate) a rumor, “check out” (appraise) a person, “check out” (withdraw) a book, or simply “check out” (die).

The earliest OED examples illustrate the first and last of those meanings, and they’re from the same year: “The singer person is checking out from the first floor suite next week” (Sewell Ford’s 1921 novel Inez and Trilby May) … “In the morning he was dead—he’d checked out in his dreams” (Los Angeles Times, April 27, 1921).

No hyphens there. But used as a noun or an adjective, the compound has sometimes been hyphenated in the past.

The noun “checkout,” which means the act or process of checking out, was a single word (no hyphen) when it first appeared in the 1940s.

This is Oxford’s earliest use: “Advancement to radio operator ‘A’ may be earned by … training that must include checkout on several types of multi-engine airplanes” (Plane Talk magazine, September 1944).

In later decades, hyphens were sometimes inserted, but they eventually fell away. OED citations include both “supermarket check-out” (1955) and “supermarket checkout” (2002).

As for the adjective, it too has occasionally been hyphenated. Oxford’s mid-20th-century examples include both “checkout systems” (1956) and “hotel check-out times” (1958). Nowadays, as we mentioned, standard dictionaries generally give the adjective as a single word, “checkout.”

If you haven’t had enough yet, we wrote a post in 2009 about the checkered history of the word “check,” which comes from Persian and is related to “chess.” Check it out.

What is a checkout girl?

checkout girl in British English (ˈt??ka?t g?ːl) a female employee who works on a supermarket checkout. She worked as a checkout girl at her local supermarket.

I’ll copy a bit here from my proto-book. The term is not specific to Git though (as chepner already said).

Thus, a [Version Control System or] VCS acts as a database of source files, with some way
of retrieving specific versions of the files. This database is called the repository. When you add updated versions of your source files, the database stores the updated sources inside the repository. Each version of a file is also called a revision, so that if you fix a spelling error and enter the updated file into the repository, you now have another revision of that file.

Used as a verb, to version means to put under control of the VCS. Used as a noun, version means a specific version taken from the VCS (of one file, or of a group of files). Usually the noun form appears with additional modifiers, as in the phrase the old version of kanga.c or version 2.1 of roo.c. If no specific files are listed, we typically mean everything, or at least everything recently under discussion: version 2.1 (of everything in the repository, or of the specific files and/or directories we were talking about). The word revision is always a noun, but otherwise means the same thing as version.

Another verb, to check in, means to store into the VCS. As you might expect, if we can check in, we can also check out, meaning extract from the VCS. Some VCSes add the verb to update, which they may use to distinguish between extracting an older version (which you check out) and moving up to the latest and (we hope) greatest (to which you update). Mercurial uses update as a pure synonym for checkout.

Check in is sometimes hyphenated (check-in), or written as one word, checkin. These avoid ambiguity: I’ll check in roo.c (look through the code to see if any wallabies got in there) vs. I’ll check-in roo.c (to store a new revision). Check out is likewise often written as one word, checkout, or hyphenated, but the verb form is still checking out, which reads much better than checkouting.

Newer VCSes add more noun-and-verb words:

• To commit means much the same as to check-in, but with some technical differences we will see in a moment. As a noun, a commit also refers to a version, but specifically one as stored by the verb form of commit.
• To clone is basically a fancy term for copying an entire repository, often from a different machine over a computer network, e.g., from a web site. As a noun, a clone is a repostory made by cloning.
• To fork is functionally the same thing as cloning, but usually with
  a different intent. The noun form a fork is thus the same as a clone, but those making making a fork may intend for their work to diverge with little or no re-synchronization (perhaps forever or perhaps for a limited time), and/or for still others to collaborate via their fork instead of the original.

Addressing Schwern’s comment about rcs co and rcs ci, it’s worth noting a few historical items:

• RCS’s checkout verb by default did not lock the (version-storage) file: it got you a read-only file in the working tree. You had to use co -l to obtain a lock, which provided you with a read/write file you could update.

• RCS’s co and ci post-dated SCCS’s checkout/checkin. However, in sccs we had two separate extraction verbs: get meant get a read-only copy and edit meant lock the file and get a read/write copy. See, e.g., the Oracle documentation for details. The «check in» command was spelled delta.

RCS was, I think, the first version control system that used the terminology that survives today. Its verbs persisted into CVS (the Concurrent Version System) and Subversion («CVS done better»), and from there, propagated into all the modern version control systems (see Wikipedia for a rather large table). Modern SCCS is a re-implementation of the earlier Unix SCCS, which itself was probably at most loosely based on the IBM SCCS that predates that.
