If you’ve ever wondered whether to write checklist, check list, or even check-list, you’re not alone. This is a common spelling question that pops up in workplaces, schools, and even casual writing. In this post, we’ll explain the correct spelling, why it matters, and how to remember it.

The Correct Spelling: Checklist

The right way to spell it is checklist (one word).

• 📚 Dictionaries agree: Merriam-Webster, Oxford, and Cambridge all list “checklist” as a single word.
• 📝 Professional writing standard: Business documents, academic papers, and productivity apps consistently use “checklist.”
• ✅ Consistency counts: Using the one-word spelling makes your writing clear and polished.

Why Not “Check List” or “Check-list”?

• Check list (two words): Once common decades ago, but now outdated.
• Check-list (hyphenated): Hyphens were used when the word was new, but like many compounds (email, notebook), it has since merged into one word.

Today, both forms are considered nonstandard. If you want your writing to look modern and professional, stick with checklist.

Easy Trick to Remember

Think of other compound words that merged into one over time:

• black board → blackboard
• note book → notebook
• check list → checklist

If you’re ever unsure, remember that checklist evolved the same way.

Examples in Sentences

• ✅ I created a checklist before the business trip.
• ❌ I created a check list before the business trip.
• ❌ I created a check-list before the business trip.

Final Word

The modern, correct spelling is checklist (one word). Using this form ensures your writing looks consistent and professional.
