The word "isone" may seem confusing in terms of spelling, but it is actually fairly straightforward when considering its pronunciation. Using the International Phonetic Alphabet (IPA), we can break down the word into its individual sounds: /aɪ/ /s/ /oʊ/ /n/. These sounds correspond to the English vowels "i," "s," "o," and "n." So, while the spelling may seem unusual at first glance, the pronunciation of "isone" is no different than many other English words.
