This might be new to you, but the words upon and Apon are commonly interchangeably used by many people. Some might think that the word Apon is not an English word and not in the dictionary but it is a legitimate English word and shares the same manner of usage. They are both prepositions but the word Apon is not commonly used in today’s modern times.
Upon means up or on an example is: The boy mounted upon his new horse. Upon could also mean being with time like: Upon her arrival, the band started to play her favorite song. Apon, on the other hand, is not commonly used today in Modern English. This was used during the Middle English era and meant the same as upon. You might catch this old preposition in old poetry and stories.
Upon is a preposition that is frequently used in sentences to give direction or relationship between two things. Apon is also a preposition in the English language. However, apon is not used as frequently as upon. Apon is a word that has not been heard of by many people. They only know how to spell that word as “upon.” Apon was used in Middle English times?
The only time that you would see the word “apon” is in old poems. Many words that are considered to be in old English were spelled a little differently, but they are easy to figure out because usually, only one letter has changed as in this example with the “a” in apon changing to a “u” in upon.
