Easy Trick to Remember the Difference
Here is a simple trick:
Think of “of course” as:
👉 “of + a course (path or direction)”
Even though the meaning is different, this idea helps you remember:
- There are two separate parts
- So it must be written as two words
Another easy trick:
👉 If you can pause slightly while speaking, it’s probably two words.
