The spelling of "most soporose" might seem puzzling at first, but it can be unraveled with the help of the International Phonetic Alphabet (IPA) system. "Most" is pronounced as /moʊst/, with two vowels (o and the open-mid back rounded vowel) blending together. "Soporose" is pronounced as /ˈsɑːpəroʊs/, with stress on the second syllable and a silent "e." The word itself means "extremely sleepy" and is a derivative of the Latin word "sopor" for deep sleep.
