Have you ever typed an important email or blog post and found yourself second-guessing whether it’s spelled “Succesfully” or “Successfully”? You’re not alone.
Misspelling words especially common ones can damage your credibility and confuse your audience. In this article, you’ll learn which version is correct, why it’s spelled that way, and how to never make this mistake again.
Let’s clear up the confusion once and for all.
✅ What’s the Correct Spelling?
The correct spelling is: Successfully
The word Successfully is the standard and grammatically correct form. The version “Succesfully” is a common misspelling caused by omitting one of the two “s” letters.
📌 Why is “Succesfully” incorrect?
- It drops a crucial “s” that comes from the base word “success.”
- There is no dictionary or language authority that recognizes “Succesfully” as a valid word.
Correct: I completed the project successfully.
Incorrect: I completed the project succesfully.
🧠 Breaking It Down: Word Origin and Structure
Etymology of “Successfully”
The word “successfully” comes from the noun “success,” which in turn comes from the Latin word successus, meaning “an advance, a good result.”
Word Formation
Success (noun) → Successful (adjective) → Successfully (adverb)
Each suffix adds a layer of meaning:
- -ful = full of
- -ly = how something is done
So, successfully means “in a way that achieves success.”
📚 Real-Life Example: When One Letter Changes Everything
Imagine this scenario:
Sara, a marketing executive, was applying for a promotion. She crafted a well-written email to her boss, summarizing her achievements. In the subject line, she wrote:
Subject: “Projects Succesfully Completed – Q2 Highlights”
Despite her strong record, her boss noticed the misspelling. It didn’t sink her promotion, but it did raise questions about attention to detail. Later, during the interview, the error was mentioned.
Moral of the story? In professional settings, spelling matters a single letter can change how you’re perceived.

📝 Common Mistakes and How to Avoid Them
❌ Dropping the Second “S”
Many users incorrectly assume only one “s” is needed after “c.” This usually happens due to pronunciation.

- ✅ Is the base word “success” spelled with double “s”?
- ✅ Did you use a grammar-check tool?
- ✅ Read aloud: Does the word sound correct?
- ✅ Compare with a trusted dictionary like Merriam-Webster.
