Apon vs. Upon, what are the differences and definitions of these English words? Most people don’t know these, so I wrote this article to clear your doubts.

In this article, we will explain what they mean, the difference between upon and apon, and list some examples used in a sentence.

Let’s get right into it.

What does Apon mean?

If the Apon is capitalized throughout, it may be an acronym for Applications Online, Association of Pediatric Oncology Nurses, ATM Passive Optical Network, Acquired Pit of the Optic Nerve, etc.

However, what does the word Apon mean? Apon is a preposition with the same meaning as upon but was used about 3 centuries ago in the Middle English Era.

You will likely find this word in historical writings, poems, and religious books. As we evolved, so did our languages. I am not a lover of history, but we have Old, Middle, and Modern English we use and speak today.

If I wrote this article in Middle or Old English, I am sure you will find it hard to read and understand unless you are a vampire. They are different eras of the English language.

Meaning of Upon


Upon is a more formal term for on, especially in abstract senses.

It is a combination of two English words, up and on. This word is a more formal preposition than on (they have the same meaning).

Differences between apon and upon

Apon was used about 300 years ago (Middle English) while upon is used today (Modern English.) That’s the significant difference between these two prepositions.

They mean the same thing. However, if you decide to use the word apon today, people will probably think you are a time traveler like Dr. Strange.

The word “apon” is often mistakenly used by individuals who either are influenced by archaic or dialectical forms of English or misunderstand its appropriateness in modern usage. In contemporary standard English, “apon” is considered incorrect. The correct preposition to use is “upon.”

Apon used in Sentences

To safe yowr sallis on dowymysday

Qwen all salles savyd mon be.

When to use upon vs. apon

These words are prepositions and should only be used before noun phrases. When using this in writing or speaking, it is quite formal.

Upon should always be used in place of apon. In this battle of English prepositions, it is clear that upon is the champion. If you want to reduce the formality in your tone, you should use on as a substitute for apon or upon.
