“Of course” and “ofcourse” may look like two possible spellings of the same expression, but only one is correct in standard English. The correct form is “of course,” written as two separate words. It is a very common English phrase used to mean certainly, naturally or without doubt. It can also be used when giving permission, agreeing with someone or indicating that something is obvious. For example if someone asks, “Can I use your phone?” you can reply, “Of course!” meaning “Certainly!” or “Yes, you may.”
The incorrect form “ofcourse” is usually the result of a spelling mistake, typing error, or confusion caused by the fact that the phrase is pronounced naturally as one connected sound in speech. Although people may sometimes write “ofcourse” informally online, it is not the standard spelling and should be avoided in formal and professional writing. Learning this simple distinction will help you write the phrase correctly in emails, essays, articles, messages and everyday communication.

- obviously
- yes

Why Is “Of Course” Written as Two Words?
Of course is a phrase made up of two separate words:
- of — a preposition
- course — a noun
Together, they form the fixed expression of course.
English contains many expressions that consist of multiple words but function together as a phrase.
For example:
- of course
- in fact
- at least
- as well
- in general
- of course not
Although these expressions may sound connected when spoken quickly, they remain separate words in writing.
Ofcourse: Is It Correct?
No.
“Ofcourse” is not the standard spelling of the expression.
You should write:
✅ Of course
not:
❌ Ofcourse
For example:
✅ Of course I remember you.
❌ Ofcourse I remember you.
The second version may occasionally appear in casual online writing, but it is considered a spelling error in standard English.

Common Mistakes
Mistake 1: Writing “ofcourse”
The most common mistake is combining the two words.
❌ Ofcourse
Use:
✅ Of course
Mistake 2: Thinking pronunciation determines spelling
When spoken quickly, of course can sound almost like one word.
However, pronunciation does not mean that the words should be combined in writing.
Mistake 3: Using “ofcourse” in professional writing
Even if you see ofcourse online, avoid it in:
- emails
- essays
- reports
- applications
- articles
- academic writing
- professional documents
Use the standard form:
of course
Mistake 4: Confusing “of course” with “course”
Of course is a fixed expression.
Course by itself has several meanings, including:
- a direction
- a series of lessons
- a route
- part of a meal
For example:
I’m taking an English course.
This has nothing to do with the expression of course.
Is “Of Course” Formal or Informal?
Of course can be used in both formal and informal English.
It is extremely common in everyday conversation:

It can also appear in formal writing:
The results are, of course, subject to further review.
However, in formal writing, the phrase should be used carefully if it makes something sound overly obvious or dismissive.

depending on the context.

Both use:

Both varieties reject ofcourse as the standard spelling.
