The correct spelling of the word "urystamine" can be explained through its International Phonetic Alphabet (IPA) transcription: /jʊˈrɪstəmiːn/. The first two letters, "ur", represent the sound "yur" as in "cure". The "y" sound is followed by "st", which produces the "ist" sound as in "mist" or "list". The "a" and "m" are pronounced as in the English word "amine". Lastly, the "i" sound is represented by the letter "e" in this spelling.
