The word "Arsemio" is quite an interesting one because its spelling doesn't match its pronunciation. In the International Phonetic Alphabet (IPA) system, it's written as /ɑrˈsimioʊ/. The first two letters "ar" are pronounced as "ahr" like in "car," followed by "sem" which sounds like "sem" as in "semester." The "i" in "io" is silent, and the "o" sounds like "oh." Therefore, "Arsemio" is pronounced as "ahr-SEM-oh." It's important to note that the spelling of a word doesn't always match its pronunciation in English.
