The spelling of the word "ruesch" can be a bit confusing, as it does not follow standard English phonetic rules. The correct pronunciation is /ɹuːʃ/, with a long "u" sound and a "sh" sound at the end. The origin of the word is German, where it is spelled "Rüsch," with an umlaut over the "u." The name is more commonly spelled "Rusch" in English, but the spelling "Ruesch" is sometimes used. When encountering unfamiliar spellings, it's always helpful to consult the IPA phonetic transcription.
