The word "wrong" is pronounced with a short "o" sound, like in "dog" or "fog," but it's spelled with a "w" and an "o" that would normally suggest a long "o" sound, like in "bone" or "tone."
This is a case of a spelling-pronunciation mismatch. Over time, the pronunciation of "wrong" changed, but the spelling stayed the same. There are many words in English with this kind of inconsistency, which can make the language a bit tricky to learn!
Here are some other examples:
* Knight: The "k" is silent.
* Gnat: The "g" is silent.
* Island: The "s" is silent.
It's just one of the many interesting oddities of the English language!
