Which word in the English language is most frequently spelled wrong?

“Mistake”

While 'mistake' refers to an error, it does not align with the riddle's play on words about the specific word 'wrong' being the answer itself.

“Incorrect”

'Incorrect' is another term for something that is not right, but it does not fit the riddle's structure, which is focused on a specific word that is 'most frequently spelled wrong.'

“Error”

'Error' signifies a mistake or fault, but it does not address the clever twist of the riddle, which points to the word 'wrong' itself as being the answer.
