What Is “Ofcourse”?
Here’s where things get simple — and a little surprising.
“Ofcourse” (written as one word) is NOT correct English.
❌ Why “ofcourse” is wrong
- It does not appear in standard English dictionaries
- It is not grammatically accepted
- It is considered a spelling mistake
🤔 Why do people still write it?
Because:
- It sounds like one word when spoken
- Many people learn English by listening, not reading
- Autocorrect doesn’t always catch it
- It’s commonly seen on social media and informal chats
🚫 Examples of incorrect usage:
- ❌ Ofcourse I will come tomorrow.
- ❌ Yes, ofcourse that’s fine.
These sentences look harmless — but in professional writing, they reduce credibility and trust.
⚠️ Important note
Even though you may see “ofcourse” online, its frequent usage does not make it correct. For SEO, academic writing, business emails, and publishing, “ofcourse” should always be avoided.
👉 Bottom line: “Ofcourse” is a mistake, not a variation.
