If you’ve ever paused mid-sentence wondering whether it’s definitely or definitely—you’re not alone. This is one of the most commonly misspelled words in English, and it catches even confident writers off guard.
Here’s the short answer: “definitely” is the correct spelling.
In this article, we’ll break down why people get it wrong, how to remember the correct version, and how to use it naturally in everyday writing. By the end, you won’t second-guess it again.
What Does “Definitely” Mean?
Definitely is an adverb that means:
- Without doubt
- Clearly or certainly
- In a way that leaves no room for confusion
Examples:
- I will definitely call you tomorrow.
- That was definitely the best meal I’ve had this week.
- She is definitely qualified for the job.
It adds certainty and confidence to your sentence.
Why Do People Misspell “Definitely”?
The most common mistake is spelling it as “definately.”
Here’s why that happens:
- People pronounce it incorrectly (“def-in-it-ly” becomes “def-in-ate-ly”)
- Confusion with similar-sounding words like “separate”
- Typing quickly without checking
Your brain hears one thing and your fingers type another. Simple as that.
The Trick to Remember the Correct Spelling
Here’s a practical way to lock it in:
Break it into parts:
Definite + ly = definitely
If you can spell “definite”, just add -ly.
Quick memory hack:
“It is finite, not finate — so it’s definitely, not definately.”
That small shift helps your brain anchor the correct version.

There’s no gray area here—“definately” is always incorrect.

Even if you know the correct spelling, these traps can still catch you:
1. Relying on autocorrect
Autocorrect won’t always save you—especially if you’ve used the wrong spelling repeatedly.
2. Typing too fast
Speed kills accuracy. Slow down slightly when writing important content.
3. Skipping proofreading
A quick reread can catch this instantly.

In professional writing:

Tip:
Don’t overuse it. Too many “definitelys” can weaken your tone.
