Picture this: You’re typing an important email to your boss, and you want to express your enthusiasm about taking on a new project. Your fingers hover over the keyboard as you wonder – is it “of course” or “ofcourse”? This common dilemma has tripped up countless writers, students, and professionals.
The Quick Answer
Let’s not keep you in suspense: “of course” is the correct spelling. It should always be written as two separate words. “Ofcourse” is incorrect and should never be used in any context, whether formal or informal writing.
Understanding “Of Course”
“Of course” belongs to a category of English phrases called fixed expressions. Like “in fact” or “at last,” these phrases maintain their separate-word structure despite being pronounced as if they were one word. The phrase combines the preposition “of” with the noun “course” to create a meaning that goes beyond its individual parts.
When to Use “Of Course”
The beauty of “of course” lies in its versatility. Here are the main situations where you’ll find this phrase particularly useful:
1. Expressing Enthusiastic Agreement
When someone makes a request or suggestion you’re happy to accommodate, “of course” adds warmth and enthusiasm to your response.
Real-life scenario:
Friend: “Would you be my plus-one at the wedding?”
You: “Of course! I wouldn’t miss it for the world!”
2. Indicating Obviousness
Use “of course” to acknowledge something that’s clearly apparent or understood.
Workplace scenario:
Colleague: “Did you include the quarterly figures in the presentation?”
You: “Of course – they’re right there in the executive summary, where they always go.”
3. Providing Reassurance
“Of course” can offer comfort and certainty when someone needs confirmation.
Family scenario:
Child: “Mom, will you come to my school play?”
Parent: “Of course, sweetheart. I’ll be sitting right in the front row.”
4. Professional Communication
In business contexts, “of course” strikes a perfect balance between formality and approachability.
Email scenario:
Client: “Could we schedule a follow-up meeting next week?”
Response: “Of course! I’ve already blocked out Tuesday afternoon for our discussion.”
Common Mistakes and How to Avoid Them

The “Ofcourse” Trap
Many writers mistakenly combine “of course” into one word, creating “ofcourse.” This error often occurs because:
- The phrase is pronounced quickly in speech
- Other similar-sounding phrases are written as one word (like “otherwise” or “nevertheless”)
- Typing quickly without paying attention to spacing
Wrong: “Ofcourse I’ll help you with the project.”
Right: “Of course I’ll help you with the project.”
The “Off Course” Confusion
Another common mix-up involves confusing “of course” with “off course.” These phrases have entirely different meanings:
- “Of course” = naturally, certainly, as expected
- “Off course” = away from the intended direction or path
Navigation scenario:
Wrong: “The ship went of course during the storm.”
Right: “The ship went off course during the storm.”
Agreement scenario:
Wrong: “Off course I’ll attend the meeting!”
Right: “Of course I’ll attend the meeting!”
Pro Tips for Perfect Usage
- Think of the Space
Remember that “of” and “course” are independent words that work together to create meaning. Visualize the space between them as you write. - Context Check
If you’re describing something deviating from its path, use “off course.” For all other situations where you mean “certainly” or “naturally,” use “of course.” - Read It Aloud
When in doubt, read your sentence aloud. You’ll naturally pause slightly between “of” and “course,” reinforcing the correct two-word spelling.
Creative Ways to Vary Your Expression
While “of course” is perfectly acceptable, you might want to vary your language for style and impact. Here are some alternatives to consider:
- For formal situations:
- “Certainly”
- “Indeed”
- “Without question”
- For casual contexts:
- “Sure thing”
- “Absolutely”
- “You bet”
Real-World Applications
Let’s look at how “of course” appears in different professional contexts:
Business Email:
“Of course, I can have those reports on your desk by tomorrow morning. I’ve already begun compiling the data.”
Customer Service:
“Of course we can accommodate your special request. Our goal is to ensure your complete satisfaction.”
Academic Writing:
“Of course, this theory must be tested against real-world applications before drawing any definitive conclusions.”
Final Thoughts
Remember, language evolves, but some rules remain steadfast. The two-word spelling of “of course” is one such rule. Whether you’re writing a casual text message or a formal business proposal, keeping “of” and “course” separate will ensure your writing maintains its professional edge.
By understanding when and how to use “of course” correctly, you’re adding a powerful tool to your communication arsenal. It’s a phrase that, when used properly, can convey certainty, enthusiasm, and professionalism all at once.
