What’s the Correct Spelling: “Of Course” or “Ofcourse”?

The correct spelling is of course — always two separate words.
The spelling “ofcourse” is incorrect ❌ in standard English.

Why? Because the phrase isn’t a single unit; it’s a combination of a preposition (of) and a noun (course) that formed a common expression over time.

Correct: “Of course, I can help you.”
Incorrect: “Ofcourse I can help you.”

Think of it this way:

Version	Correct?	Why
of course	✅ Yes	Proper structure, grammatically valid
ofcourse	❌ No	Not recognized formally or academically
Of Course	✅ Yes	Capitalized at start of sentence/title

If you write for exams, professional emails, corporate memos, academic papers, or published content, always use of course.
