If you have ever wondered whether “of course” should be written as two words or one, you are not alone. This common English expression appears everywhere in conversations, emails, articles, and everyday writing. Because many English expressions combine words over time, it is easy to assume that “ofcourse” might also be an acceptable spelling.
The correct form is “of course”—always written as two separate words in standard English. “Ofcourse” is generally considered a misspelling. The phrase is commonly used to mean “certainly,” “naturally,” or “as expected.” Understanding the correct spelling is especially useful for students, ESL learners, writers, and anyone who wants to communicate clearly and professionally.
Quick Answer
“Of course” is correct, while “ofcourse” is incorrect in standard English. The expression is always written as two words. Use of course when you mean “certainly,” “naturally,” or “yes.” Avoid writing ofcourse in formal or standard English.
Why People Confuse It
People often confuse of course and ofcourse because they are pronounced together as a single phrase in normal speech.
When spoken quickly, the words can sound like one unit. This makes it tempting to write them as one word.
Another reason is that English contains many compound words that have developed from separate words. For example:
- always is one word.
- already is one word.
- of course remains two words.
- ofcourse is not the standard spelling.
Typing habits can also contribute to the mistake, especially when people write quickly in text messages or on social media.
First Word: Of Course
Of course is the correct expression.
It is a common phrase used to express:
- certainty
- agreement
- permission
- something expected or obvious
- polite confirmation
Examples
- Of course, I can help you.
- She will of course attend the meeting.
- Of course, you can borrow my book.
- He was of course surprised by the news.
The phrase can appear at the beginning, middle, or end of a sentence depending on the intended emphasis.
Second Word: Ofcourse
Ofcourse is not the standard English spelling.
Although you may see it in informal online writing, social media posts, comments, or messages, it should generally be treated as a spelling error.
❌ Ofcourse, I will help you.
✅ Of course, I will help you.
If you are writing an essay, email, article, application, report, or professional message, use of course.

Common Mistakes
1. Writing “Ofcourse”
❌ Ofcourse I understand.
✅ Of course I understand.
The two words should remain separate.
2. Using It as One Word Because It Sounds Connected
English pronunciation does not always tell you where word boundaries belong.
Even though of course may sound like one connected phrase, it is written as two words.
3. Treating It Like a Compound Word
Some expressions eventually become single words, but that does not mean every frequently used phrase follows the same pattern.
Of course has not become ofcourse in standard English.
4. Using Incorrect Spelling in Professional Writing
A spelling error such as ofcourse can make an otherwise polished email or article look less professional.
For formal communication, always choose of course.
Memory Trick
Use this simple trick:
“Of” + “course” = two words, of course!
Think of the phrase as describing something that is naturally or certainly the case.
You can also remember:
Of course = two words, no doubt.
Whenever you type ofcourse, pause and separate it into of course.
American vs British English
There is no meaningful spelling difference between American and British English for this expression.
Both varieties use:
of course
American English:
Of course, I’ll help you.
British English:
Of course, I’ll help you.
The expression has the same basic meaning in both varieties of English.
