Of Course or Of course: Which One Should You Use?

Of course: which one should you use? This question jumps off the page, grabbing attention immediately. Most people mistype “of course” as “of course”, thinking it’s acceptable, but in reality, the two aren’t interchangeable. Let’s dive into why that separation of + course matters so much for clarity, correctness, and even credibility in your writing.

Every day, writers and students face spelling confusion, swapping between “of course,” “of course,” and even “off course spelling.” Mistakes here may seem minor, yet they reveal deeper gaps in understanding grammar and correct English usage. What you write reflects how well you know language, so nailing course-correct spelling shows polish and professionalism.

You might wonder: which is correct, of course or course? The answer isn’t just about what looks right, it is about meaning and tone in context. In this post, you’ll explore the meaning of course spelling, and whether it’s of course or course, and get pro tips for avoiding frequent mistakes once and for all.

First Paragraph

Of course stands apart from of course not only visually but grammatically, and this tiny space between “of” and “course” carries weight. People who type “of course spelling” often do so because they’ve seen it floating around online. Yet every reputable dictionary, grammar guide, and style manual treats of course correct spelling as the only valid form. In short, is it, of course, a word? No, it isn’t recognized in standard English grammar. That misplaced closure turns an everyday phrase into a typo, one that can undermine writing clarity and professionalism.

Understanding the Difference: Is it of course or course?

What Does “Of Course” Mean?

“Of course” is a standard phrase used to indicate something is obvious or expected. Think of it as shorthand for “as naturally as a course follows a path.” Meanwhile, is it of course correct? No this form doesn’t appear in dictionaries or formal usage guidelines.

Why “Of course” Spelling Is Incorrect

Typing of course as one word muddies grammar and makes your work look sloppy. It’s a frequent example of spelling confusion, especially among non-native speakers or casual writers. Remember: the grammar, of course, is simply wrong. There’s no rule saying “of course” should ever be accepted.

Grammar Guidance: Is of course a word?

In proper grammar, “of” is a preposition and “course” is the object. Together, they form a phrase not a compound word. For clarity, grammar, of course, doesn’t permit merging them. English spelling rules favor two-word pairings in many set phrases, and this one fits that rule. So if you’ve wondered, is of course a word, the answer remains firm: it doesn’t meet standard usage.

When to Use “Of Course” vs. “Of course”

Use “of course” whenever you want to say something is expected, promised, or obvious. Avoid “of course” in any writing, formal or informal. While text messages may slip it in, any professional writing from emails to blog posts demands precision. If someone asks, of course, meaning, refer them to “of course,” period.

Scenario Examples

• Email Example (business)
  Subject: Meeting tomorrow
  Hi Jane,
  Of course, I’ll be there at 10 a.m. Let me know if, of course, spelling is still giving you trouble. See you then. Regards, Mike
• Casual Text
  “Of course, I’ll grab coffee later 😂”
  Here, “of course” sounds conversational. If someone wrote “of course I’ll grab coffee,” it just looks like a misspelling.
• Blog Post Snippet
