The spelling of the word "LIFES" is incorrect. The correct spelling of the singular form of the word is "LIFE" and the plural form is "LIVES". The pronunciation of the word "LIFE" is /laɪf/, while the pronunciation of "LIVES" is /laɪvz/. The addition of "-es" at the end of "life" changes the pronunciation to /laɪvz/. Therefore, it is important to use the correct spelling and pronunciation to effectively communicate in written and spoken language.
