Checkout vs. Check Out: Grammar, Usage, and Real-Life Examples
The difference between checkout and check out lies in their grammatical roles:
- Checkout (one word) is a noun or adjective. Example: “I went to the supermarket checkout.”
- Check out (two words) is a verb. Example: “I need to check out of the hotel by noon.”
Occasionally, the noun form is hyphenated as check-out, but the unhyphenated version is more widely accepted in modern English.
The Origin of Checkout and Check Out
Origin of the Word “Check”
The word check comes from the Old French eschequier, meaning a chessboard or a mark of inspection. Over centuries, it evolved in English to mean verification, control, or examination.
Formation of Checkout
By combining check with out, the verb phrase check out was formed. Over time, the noun form describing the location or process of paying (like a supermarket or hotel) became checkout.
Why One Word vs. Two Words Exists
English often transforms verb phrases into nouns over time. Similar to setup (noun) vs set up (verb), checkout follows this pattern. The two-word form remains the verb, while the single word describes the location or concept.
British English vs. American English Usage
British English Usage
- In the UK, checkout is standard for stores or online purchases.
- The verb remains check out, as in: “Please check out of your room before 11 am.”
American English Usage
- Americans also use checkout for the noun and check out for the verb.
- Hyphenation (check-out) is rare but acceptable in some formal writing.
