On and upon
What’s the difference between on and upon? The short answer is; a difference in formality. ‘On’ is generally considered to be more common, and is preferred for everyday use. ‘Upon’ on the other hand, is far more formal, and should not be used all the time, instead of ‘on’.
The two words, on and upon are mostly interchangeable, but not always.
Usually, anytime that ‘on’ is being used, ‘upon’ could take its place, if the speaker wanted to do so. It’s generally best to use ‘on’ most of the time and use ‘upon’ more sparingly.
