A routine checkup or check-up is something most people know they should do but many still get confused about how to write the word correctly. Is it “checkup,” “check-up,” or both? The answer depends on grammar rules, style guides, and even regional English differences.
If you’re writing about a medical checkup, a dental visit, or a general health examination, choosing the correct spelling matters for clarity and professionalism. In this guide, you’ll learn the correct usage, differences, examples, and common mistakes so you can confidently use the term in writing.
