The spelling of the word "more bettered" is incorrect as it is a double comparative form. The correct comparative form is "more better." The IPA transcription for "more better" is /mɔːr ˈbɛtər/. The first syllable "mor" is pronounced with a long "o" sound, while the second syllable "bet" has a short "e" sound. The final syllable "er" is pronounced with a neutral schwa sound. It is important to pay attention to the correct spelling and pronunciation of words to effectively communicate in English.
