Of Course or Ofcourse: Which One Should You Use?

When you hear the phrase of course, it rolls off the tongue naturally. But seeing it written out can spark a question: should it be ofcourse or of course as one? This confusion is common, and many people wonder which is the correct spelling and usage. Let’s clear up the confusion and explain everything you need to know about of course vs ofcourse.

Quick Summary

Of course is the correct spelling—two words meaning certainly or naturally. Ofcourse is a common misspelling with no proper meaning. Always use of course in writing to sound clear and professional.

Why Does Confusion About “Ofcourse” vs “Of Course” Exist?

English can be tricky, especially when it comes to phrases that feel like single words when spoken. The phrase “of course” is often miswritten as “ofcourse,” especially in texting, social media, or casual writing. The mistake happens because people hear the phrase as one word and try to match that in writing.

Here are some reasons why this confusion persists:

• Fast typing habits: People tend to drop spaces to type quickly.
• Autocorrect errors: Some devices incorrectly suggest “ofcourse.”
• Lack of grammar awareness: Writers unfamiliar with English grammar rules make mistakes.
• Influence of other compound words: Some two-word phrases eventually become one word (e.g., “alot” is incorrect, but “anyone” is correct).

Despite these reasons, “ofcourse” is not a valid English word. It’s simply a misspelling.

Historical Background

The phrase “of course” dates back to the late Middle Ages, around the 15th century. It originally meant “according to the natural order” or “as a matter of course,” suggesting something that happens naturally or logically.

• The word “course” in this phrase comes from the Latin cursus, meaning “a running,” “a course,” or “a path.” Over time, course in English evolved to refer not just to physical paths but also to the “course of events” or “natural order.”
• Combining “of” with “course” formed an idiomatic expression used to describe something expected or inevitable.
