Ofcourse or Of Course—have you ever wondered whether this is just a spelling variation or two completely different forms in the English Language? Many English learners often get confused between these two because they look almost identical, yet only one form is considered correct in standard usage.
The simple truth is that Of Course (written as two separate words) is the correct spelling, while Ofcourse (written as one word) is a common mistake usually seen in informal writing, fast typing, or misunderstanding of English grammar rules. This confusion frequently appears in searches like “of course or ofcourse,” “which is correct of course or ofcourse,” and “correct spelling of of course.”
In English grammar, Of Course is a fixed phrase used to express certainty, agreement, politeness, or something that is naturally expected. It is widely used in everyday conversations, emails, academic writing, and professional communication. However, many learners incorrectly merge it into one word due to pronunciation habits and typing speed, even though it does not follow standard English usage rules.
This issue is closely related to broader topics in English Grammar and English Language learning, especially areas involving spelling accuracy, vocabulary usage, and commonly confused words. Understanding the correct usage of Of Course vs Ofcourse helps improve writing clarity, communication skills, and overall language confidence.
In this guide, you’ll learn the correct meaning, usage rules, real-life examples, and simple memory tricks so you never confuse them again in writing or conversation.
Quick Answer: “Ofcourse” vs. “Of Course” (Simple Rule)
Let’s make it simple right away:
- Of course = Correct ✅
- Ofcourse = Incorrect ❌
Easy Memory Trick
Think of it like this:
“Of” and “course” are two separate ideas that just work together.
If you can separate them in your mind, you should separate them in writing.
Why People Get Confused
This mistake doesn’t come from ignorance—it comes from patterns.
1. Fast typing habits
People type quickly and merge words without noticing.
2. Spoken English influence
When spoken, “of course” sounds like one smooth phrase.
3. Social media usage
You’ll often see “ofcourse” online—even though it’s incorrect.
4. Autocorrect inconsistency
Some devices don’t always correct it, so the mistake spreads.
The Grammar Rule Behind “Of Course”
To understand why it’s two words, break it down:
- “Of” → a preposition (shows relation)
- “Course” → a noun (meaning a natural path or expected way)
Together, “of course” means:
something that is expected, obvious, or naturally true
English keeps them separate because they are still two different grammatical parts, even when used as a fixed phrase.

Biggest Mistake People Make
Here’s the real issue:

So what’s the truth? Should you write “of course” or “ofcourse”?
This confusion is extremely common because English often merges spoken phrases in our minds, but not in writing. In speech, “of course” flows like a single sound. In writing, however, grammar rules are stricter.
