Checkout and check out sound the same, but they do different jobs in a sentence.
Checkout, written as one word, is usually a noun or an adjective. It often refers to the place or process of paying, or it describes something related to that process. For example, you might say, The checkout line was long or Use the checkout page to finish your order.
Check out, written as two words, is a verb phrase. It can mean to leave a hotel, examine something, borrow something, or complete payment. For example, We need to check out by 11 a.m. You can also say, Please check out this article.
- Use checkout for things, places, or descriptions.
- Use check out for actions.
- If you can replace it with a verb like inspect or leave, you probably need two words.
A simple test helps: if the phrase shows what someone is doing, choose check out. If it names a payment area, a process, or a related feature, choose checkout.
