Ofcourse or Of Course: Which Is Correct?

A tiny space can completely change whether a word or phrase is considered correct. If you’ve ever wondered “ofcourse or of course?”, you’re dealing with a very common English spelling mistake.

The correct spelling is of course, written as two separate words. “Ofcourse” is a common misspelling and is not the standard form used in formal or edited English. Once you understand how the phrase works, remembering the of course spelling becomes easy.

Ofcourse or Of Course: Which One Is Correct?

If you’re choosing between ofcourse or of course, the answer is straightforward:

Of course is correct.

Ofcourse is generally considered incorrect in standard English because the phrase is made up of two separate words: of and course.

Correct: Of Course

Use of course when you want to show that something is obvious, expected, certain, or willingly agreed to.

Examples:

• Of course, I’ll help you.
• She can come with us, of course.
• Of course he remembered your birthday.
• You can borrow my book, of course.

Incorrect: Ofcourse

In standard English writing, avoid writing:

• Ofcourse I’ll help you.
• Ofcourse she knows.

Instead, write:

• Of course I’ll help you.
• Of course she knows.

The difference is simply the space, but that space matters.

What Does “Of Course” Mean?

Of course is a common English phrase with several closely related meanings.

It can indicate that something is:

• Obvious or expected
• Certainly true
• Naturally accepted
• Freely agreed to
• A polite acknowledgment

For example:

“Can I ask you a question?”
“Of course.”

Here, of course means yes, certainly or sure.

In another sentence:

“Of course the store is closed on Sunday.”

Here, it suggests that the speaker considers the information obvious or unsurprising.

Of Course Spelling: Why Is It Two Words?

The of course spelling can be confusing because the phrase is frequently spoken quickly. In conversation, of course can sound almost like a single unit.

However, pronunciation doesn’t determine whether words should be written together.

The phrase consists of two separate words:

of + course = of course

This is similar to other English expressions that are pronounced smoothly but remain separate words in writing.

How to Use “Of Course” in a Sentence

Understanding the phrase becomes much easier when you see how it works in real sentences.

To show agreement

“Could you help me with this?”
“Of course.”

To emphasize something obvious

**Of course, water freezes at a sufficiently low temperature.

To give permission

“Can I use your phone?”
“Of course.”

To add an aside or acknowledgment

The restaurant was busy, of course, because it was a Friday night.

In this use, of course adds information that the speaker expects the reader or listener to understand.

Of Course vs. Ofcourse in Formal Writing

The distinction becomes especially important in professional and academic writing.

If you’re writing:

• A school assignment
• A business email
• A report
• A résumé
• An article
• A formal letter
• A website

use of course, with a space.

While people may type “ofcourse” in casual messages or online conversations, that doesn’t make it the standard spelling.

Form	Correct?	Example
of course	Yes	Of course, I’ll be there.
ofcourse	No	Ofcourse, I’ll be there.

Why Do People Write “Ofcourse”?

The ofcourse spelling mistake usually happens because of course is so frequently spoken and read as one phrase.

There are also many English words that are correctly written as single words even though they may have originally developed from separate words. This can make it difficult to know when a phrase should remain separated.

In this case, however, the standard spelling is firmly established:

of course

not:

ofcourse

Is “Of Course” One Word or Two?

Of course is two words.

This is one of the easiest ways to remember the answer to “ofcourse or of course?”

Think of it as:

OF + COURSE

There is always a space between the two words when you’re using the standard expression.

Phrases Similar to “Of Course”

Depending on the context, you may be able to replace of course with another phrase.

Some alternatives include:

• Certainly
• Definitely
• Naturally
• Surely
• Absolutely
• Without a doubt
• Sure
• Yes

For example:

Of course, I’ll attend.

could become:

Certainly, I’ll attend.

However, these alternatives don’t always carry exactly the same conversational tone. Of course often sounds warmer and more natural in everyday conversation.

Common Mistakes With “Of Course”

Here are some errors to watch for.

1. Writing “ofcourse”

This is the most common mistake.

Incorrect: Ofcourse I understand.
Correct: Of course I understand.

2. Forgetting the space after a comma

When of course begins a sentence as an introductory phrase, a comma is often appropriate:

Of course, you’re welcome to join us.

3. Overusing “of course”

Although perfectly correct, repeating the phrase too often can make writing sound dismissive or overly conversational.

For example:

Of course, we know this. Of course, everyone understands it. Of course, the answer is obvious.

In formal writing, varying your wording can make the passage sound more polished.

“Of Course” at the Beginning or End of a Sentence

The phrase can appear in different positions.

At the beginning

Of course, I’ll call you later.

In the middle

She will, of course, need more time.

At the end

You can join us, of course.

The position can slightly change the tone or emphasis, but the spelling remains the same.
