English learners, students, and even native speakers often get stuck on small spelling details. One of the most common confusions is whether the correct form is “of course” or “ofcourse.”
At first glance, the one-word version might feel right because of how quickly we say it in speech. But is it actually correct? Let’s clear the confusion once and for all.
Why Spelling Matters in Everyday Communication
Small spelling choices can have a big impact. Whether you’re writing an email, a blog post, or even a social media caption, using the wrong form can undermine credibility. For professionals, students, and writers, choosing the right spelling of “of course” ensures clarity and helps you look polished.
The Correct Form: “Of Course”
Why “Of Course” Is Right
The correct spelling is “of course” (two words). The phrase has been part of English since the 18th century and is widely used to express agreement, certainty, or obviousness. For example:
- “Of course, I’ll help you with your assignment.”
- “It was, of course, the right decision.”
Common Grammar Rule
It combines the preposition “of” with the noun “course.” Together, they create an idiomatic expression that means naturally or certainly.
Why “Ofcourse” Is Incorrect
