The spelling of the word "Hierome" may seem unusual to many people. This is because it is an archaic version of the name "Jerome", which has since undergone various spelling changes. The pronunciation of "Hierome" can be explained using the IPA phonetic transcription as /haɪrəʊm/. The "H" at the beginning is silent, and the stress is on the second syllable "ro". This spelling and pronunciation was common in the 16th and 17th century, but is not commonly used today.
