The spelling of the word "mumo" might seem odd, but it makes sense when you consider its pronunciation. In IPA phonetic transcription, "mumo" is pronounced as /ˈmuːməʊ/. The "m" at the beginning of the word represents the "m" sound, while the letters "o" and "u" together make the "oo" sound. The second "m" represents another "m" sound before the final "o" sound. So while the spelling might look unusual, it accurately represents the sounds in the word.
