Many people wonder whether to write “of course” as one word or two. The phrase is common in both spoken and written English. However, there is confusion about its correct spelling. Some mistakenly believe that “ofcourse” is a valid word.
In reality, “of course” is the correct form. It is a two-word phrase used to express certainty, agreement, or an expected outcome. The incorrect form, “ofcourse,” is a common misspelling.
This article will explain the difference, provide examples, and explore the origins of “of course.” You will also learn its synonyms and how to use it in different contexts. By the end, you will confidently use “of course” in your writing and speech.
Why is There Confusion?
Many English learners and even native speakers mistakenly write “ofcourse” as one word. This happens because people often pronounce it quickly, making it sound like a single unit. When spoken, the space between “of” and “course” is not always clear.
Another reason for the confusion is the pattern of other compound words. Words like “altogether” and “anywhere” started as separate words but later became one. However, “of course” never followed this pattern. It has always been two words in proper English.
Autocorrect and informal writing also add to the problem. Many people type fast and forget the correct spacing. Some spell-check tools do not always flag “ofcourse” as incorrect, leading to further mistakes.
The Correct Usage: “Of Course” vs. “Ofcourse”
Many people question whether “of course” should be written as one word or two. The answer is simple. “Of course” is always two words. The incorrect form, “ofcourse,” does not exist in standard English. Understanding the difference is important for both writing and speaking correctly.
“Of Course” – The Correct Term
The phrase “of course” means something is obvious, expected, or natural. It expresses agreement or confirms information. This phrase is common in daily conversations, academic writing, and professional communication.
Examples:
- Of course, I will help you with your homework. (Agreement)
- This hotel has free Wi-Fi, of course. (Expectation)
- Can you finish the project by tomorrow? Of course. (Confirmation)
The words “of” and “course” work together as a prepositional phrase. The word “course” refers to a natural or expected path, reinforcing its meaning.
“Ofcourse” – A Common Misspelling
The incorrect spelling “ofcourse” is a common mistake. Many people assume it follows the pattern of words like “anyone” or “somewhere,” but English does not allow “of” and “course” to merge.
Examples of incorrect usage:
I will, ofcourse, attend the meeting. (Wrong)
I will, of course, attend the meeting. (Correct)
Autocorrect tools sometimes fail to catch this mistake. However, most dictionaries do not recognize “ofcourse” as a valid word. Using the correct form improves clarity and ensures proper grammar.

The Origin and Etymology of “Of Course”
The phrase “of course” has been in use for centuries. It comes from the word “course,” which originally referred to a natural or expected path. In Old French, “cours” meant a flow or movement, similar to how a river follows its course. English adopted this meaning, and by the 16th century, “of course” was used to express something that happens naturally or predictably.
Writers and speakers began using it in both literal and figurative ways. Over time, it became a common phrase to confirm facts, show agreement, or express expectations. Unlike other phrases that evolved into single words, “of course” has always remained two separate words in standard English.
This historical background explains why “of course” makes sense as a phrase, while “ofcourse” remains incorrect.
Common Mistakes and How to Avoid Them
Many people mistakenly write “ofcourse” as one word. This is a common spelling error, especially in informal writing. The correct form is always “of course” with a space between the two words. Understanding why this mistake happens can help prevent it.

✅ Correct: Of course, you can join us.
