The phrase "fruit adultery" may seem like an odd combination of words, but its spelling is straightforward once you break it down phonetically. The first word, "fruit," is spelled /fru:t/ in IPA, with the vowel sound represented by the symbol ":" indicating a longer sound than the single letter "u" typically represents. The second word, "adultery," is spelled /əˈdʌltəri/ in IPA, with the stress on the second syllable and the "e" in "adulter" pronounced as a schwa sound. So, "fruit adultery" is spelled /fru:t ˈədʌltəri/.
