Quick Answer
Of course is the correct spelling, and it must be written as two words. Ofcourse is incorrect in standard English. The phrase means “certainly,” “naturally,” or “without doubt.” Use of course when agreeing, expressing certainty, or referring to something expected. For example: “Of course, I will help you.”
Why Do People Confuse Of Course and Ofcourse?
People often confuse of course and ofcourse because the phrase is pronounced smoothly, making it sound like one word during normal conversation.
English contains many compound expressions, and some are written as separate words while others are combined. Because of course is so common, writers may mistakenly join the two words together when typing quickly.
However, standard English always writes this expression as of course.
Consider these examples:
- Correct: Of course, you can join us.
- Incorrect: Ofcourse, you can join us.
- Correct: She will, of course, arrive on time.
- Incorrect: She will, ofcourse, arrive on time.
The meaning remains understandable when the words are joined, but the spelling is still incorrect. Remembering that of course consists of two words will help you avoid this common mistake.
First Word: Of Course
Of course is a standard English expression used to show agreement, certainty, willingness, or that something is expected.
It is an adverbial phrase, meaning that it often functions like an adverb by modifying a statement or expressing the speaker’s attitude toward it.
Meaning of Of Course
The phrase has several closely related meanings depending on the situation.
1. Certainly or yes
Use of course to agree to a request or confirm that something is possible.
Example: “Can you help me with this assignment?”
“Of course!”
2. Naturally or as expected
Use it when something seems normal, logical, or predictable.
Example: Of course, children need enough sleep.
3. Without doubt
Use it to express confidence or certainty.
Example: She is, of course, welcome to attend the meeting.
4. To acknowledge an obvious fact
Sometimes, of course introduces information that the speaker considers obvious or already known.
Example: Of course, water freezes at sufficiently low temperatures under ordinary conditions.
Examples of Of Course in Sentences

- Of course, she knows the answer.
- Of course, we should respect other people.
- He will, of course, attend the meeting.
- Of course, you can ask questions.
- Of course, I remember your birthday.
- The journey will take time, of course.

Is Of Course Two Words?
Yes. Of course must be written as two words in standard English.
Correct:
- Of course, I agree.
- She is of course welcome to join us.
- Of course, we can discuss it later.
Incorrect:
- Ofcourse, I agree.
- She is ofcourse welcome to join us.
Whether the phrase appears at the beginning, middle, or end of a sentence, its spelling remains the same.
Second Word: Ofcourse
Ofcourse is an incorrect spelling of the expression of course. It is not accepted as a standard one-word form in modern English.
Writers commonly make this mistake because the expression is frequently spoken and typed. However, combining the words does not make the spelling correct.
Why Is Ofcourse Incorrect?
The expression consists of two separate words:
- Of: A preposition used in many English expressions.
- Course: A noun that can refer to a path, direction, class, or sequence of events.
Together, the words form the established expression of course. Its spelling is fixed, so the words should not be joined.
Incorrect and Correct Examples
| Incorrect | Correct |
|---|---|
| Ofcourse, I can help. | Of course, I can help. |
| Ofcourse she is right. | Of course, she is right. |
| Thank you. Ofcourse! | Thank you. Of course! |
| I will ofcourse attend. | I will, of course, attend. |
| Ofcourse you can come. | Of course, you can come. |
Important: Even if readers understand ofcourse, it remains a spelling error in standard writing. Use of course in schoolwork, professional emails, essays, and everyday messages.
Of Course vs Ofcourse: Comparison Table
| Feature | Of Course | Ofcourse |
|---|---|---|
| Correct spelling | Yes | No |

| Suitable for formal writing | Yes | No |

The difference is simple: of course is correct, while ofcourse is a misspelling. Unlike some word pairs that have regional spelling variations, this expression does not have a standard one-word alternative.
When Should You Use Of Course?
Use of course whenever you want to express agreement, certainty, willingness, or something expected. The spelling always stays the same, but its tone and meaning can change slightly with the context.
1. Use Of Course to Agree to a Request
When someone asks you for help or permission, of course can be a friendly way to say yes.
Examples:
- “Can I borrow your pen?” “Of course!”
- Of course, I can help you with your homework.
- “Would you mind opening the window?” “Of course not.”

Choose the version that best suits your purpose and audience.

Common Mistakes With Of Course
Although of course is easy to understand, there are a few common mistakes worth avoiding.
Mistake 1: Writing Ofcourse as One Word
Incorrect: Ofcourse, I will help you.
Correct: Of course, I will help you.
This is the most common spelling mistake. Always keep the words separate.
Mistake 2: Assuming Ofcourse Is an Informal Alternative
Some people use ofcourse in text messages or online conversations because they are typing quickly. However, informal communication does not make the one-word spelling standard.
Correct: Of course, see you tomorrow!
Incorrect: Ofcourse, see you tomorrow!
Mistake 3: Adding Unnecessary Punctuation
When of course begins a sentence and introduces the main statement, a comma is often appropriate.
Example: Of course, I can help.
When the expression appears in the middle of a sentence as an aside, commas can separate it from the rest of the sentence.
Example: I will, of course, send you the details.
Punctuation depends on the sentence structure, but it does not affect the two-word spelling.
Mistake 4: Using Of Course When You Mean Something Else
Of course usually expresses agreement, certainty, or an expected fact. It does not always mean exactly the same thing as because, therefore, or for example.
Incorrect: I stayed home of course it was raining.
Better: I stayed home because it was raining.
If you want to explain a reason, use because. Use of course when you want to express certainty, agreement, or something expected.
Mistake 5: Using Of Course in a Way That Sounds Impolite
Depending on tone, of course can sometimes sound impatient or suggest that a question should have been obvious.
For example:
- Friendly: “Can you help me?” “Of course!”
- Potentially dismissive: “Of course you don’t understand.”
Choose your words and tone carefully so your message sounds respectful.
Memory Trick: How to Remember Of Course or Ofcourse
Here is an easy way to remember the correct spelling:
Of course = two words, one expression.
Think of the phrase as two separate building blocks: of + course. Even though they work together to express one idea, they remain separate words.
Try this simple memory sentence:
“Of course, I know the correct spelling.”
Whenever you write the phrase, ask yourself whether you have left a space between of and course.
- Correct: of course
- Incorrect: ofcourse
You can also remember that expressions such as in fact, at least, and of course contain separate words. Learning common expressions as complete phrases can help you spell them correctly.

British English
