The spelling of the word "muivah" can be explained using the International Phonetic Alphabet (IPA). The first sound, "m", represents a voiced bilabial nasal consonant. The following sound, "ui", represents a diphthong that begins with an unrounded close-mid front vowel "ɪ" and ends with a rounded close-mid back vowel "ʊ". The final sound, "vah", represents a voiceless labiodental fricative consonant "f" followed by an unvoiced velar fricative consonant "x". Therefore, the correct pronunciation of "muivah" is /mʊɪfɑː/
