"Ulosis" is a rare medical term that refers to the presence of ulcers or an ulcerous condition of the body. The spelling of this word can be explained using IPA phonetic transcription: /juːˈləʊsɪs/. The first syllable, "u-" is pronounced the same as the word "you." The second syllable, "-lo," is pronounced with a long "o" sound, like in the word "low." The final syllable, "-sis," is pronounced with a short "i" sound, like in the word "sis." Thus, "ulosis" is pronounced "you-low-sis."
