You are typing a fast message. You want to say “yes, sure.” Your fingers write “ofcourse.” Then you stop. Does that look right? You open a new tab and search “ofcourse or of course.”
You are not alone. Many people ask this every month. The phrase is short and common, so a small slip stands out. Spell checkers do not always catch it. And you may see “ofcourse” in texts and posts, so it can look fine.
This article clears up the confusion. Here is the short answer: “of course” is two words. That is the correct spelling in the US, the UK, Canada, Australia, and everywhere else. “Ofcourse” is a mistake.
You will learn where the phrase comes from and why people mix it up. You will also see how it differs from real British and American spelling changes. We will cover common errors, real examples, and simple advice for work and school. Let’s begin.
Quick Answer
Use “of course.” Always two words.
“Of course” means “naturally,” “certainly,” or “as you would expect.”
- “Can you help me?” “Of course!“
- “Of course I remember your birthday.”
- “She is late, of course.”
“Ofcourse” is not a word. No major dictionary lists it. If you write it, readers may think you made a typing error.
Quick memory trick: You would not write “ofthe” or “ofall.” So do not write “ofcourse.”
The Origin of “Of Course”
The phrase has two simple parts: “of” and “course.”
“Course” comes from the Latin word cursus, which means “a running” or “a path.” It passed through Old French (cours) into English. It first meant a path or direction. Later it came to mean the usual way things go.
That is the key to the phrase. “Of course” first meant “in the normal course of things.” If something happens “of course,” it follows the natural path. Over time it came to mean “naturally” or “obviously.” You see the same idea in other phrases:
- “In due course” (at the proper time)
- “Matter of course” (the normal thing)
- “Par for the course” (what you expect)
Why does “ofcourse” exist? People often run short phrases together as they type. Many writers do this with “alot,” “incase,” and “aswell.” Fast texting makes it worse. Say it out loud and it sounds like one word: “uhv-course.” So the brain wants to write it that way. But the standard spelling has never changed. It has always been two words.
British English vs American English Spelling
Here is something important. This is not a British vs American issue. Both use “of course.” There is no UK spelling and no US spelling of “ofcourse.”
Many words do differ between the two. Look at these:
| Word type | American English | British English |
| -or / -our | color | colour |
| -ize / -ise | organize | organise |
| -er / -re | center | centre |
| -ense / -ence | defense | defence |
| Single / double L | traveling | travelling |
| of course | of course | of course |
| ofcourse | incorrect | incorrect |
Rules like “color vs colour” are real regional choices. “Of course” is not on that list. People sometimes assume it is, because they see two spellings online. But one of them is simply wrong.
Which Spelling Should You Use?
The answer is easy: “of course” for everyone.
- US readers: Use “of course.”
- UK and Commonwealth readers (Canada, Australia, India, South Africa): Use “of course.”
- Global or mixed audience: Use “of course.”
- Business, school, or legal writing: Use “of course.”
- Texts and social media: Still use “of course.” It takes one extra tap, and it looks more careful.
You do not need to pick a side. This is one of the few spellings where the whole English-speaking world agrees.
Common Mistakes with “Of Course”
1. Writing it as one word
- Wrong: Ofcourse I will come.
- Right: Of course I will come.
2. Mixing up “of course” and “off course”
“Off course” means away from the planned path.
- Wrong: The ship went of course.
- Right: The ship went off course.
3. Spelling “course” like “coarse”
“Coarse” means rough, like coarse sand.
- Wrong: Of coarse!
- Right: Of course!
4. Typing “of cource” or “of corse”
- Wrong: Of cource, I agree.
- Right: Of course, I agree.
5. Using it too much in formal writing
“Of course” can sound like “you should already know this.” Use it with care in emails to clients or bosses.
“Of Course” in Everyday Examples
Emails
- “Of course, I can send the report by Friday.”
- “Thank you for your help. Of course, let me know if you need more.”
News writing
- “The team, of course, hopes to win the final.”

Formal writing

Notice how the phrase works in each case. It adds a feeling of “naturally” or “as expected.”
