The spelling of "mcnutt" can be confusing because it does not follow typical English spelling conventions. The correct pronunciation of "mcnutt" is /məˈnʌt/. The "mc" at the beginning is pronounced as one sound, like "mick", and the "n" in the second syllable is emphasized. The double "t" at the end of the word is also important and should not be left out, as it changes the vowel sound in the preceding syllable. Overall, mastering the correct spelling of "mcnutt" requires both knowledge of IPA phonetics and practice in sounding out the word correctly.
