Identifying the Incorrect Spelling

This question requires us to identify which of the provided English words is spelled incorrectly. Let's examine each option:

• Malfeasance: This word is spelled correctly. It refers to wrongdoing or misconduct, especially by a public official.
• Magnanimous: This word is spelled correctly. It means generous or forgiving, especially toward a rival or someone less powerful than oneself.
• Insatiable: This word is spelled correctly. It describes someone or something that cannot be satisfied.
• Perserverance: This word contains a spelling error. The correct spelling is Perseverance. It means persistence in doing something despite difficulty or delay in achieving success. The incorrect version uses 'e' where it should be 'e' (this is incorrect, it should be 'e' instead of 'e'). Wait, let me recheck. The correct spelling is P-E-R-S-E-V-E-R-A-N-C-E. The option provided is P-E-R-S-E-V-E-R-A-N-C-E. Ah, the error is the 'e' in the second to last syllable. It should be 'a', not 'e'. Let's clarify this. The word is Perseverance. The option spells it as 'Perserverance'. The mistake is indeed the 'e' instead of 'a' in the second to last syllable. So, the correct spelling is Perseverance.

Therefore, the word with the incorrect spelling is Perserverance.
