The correct spelling of the phrase "most show me" can be explained using the International Phonetic Alphabet (IPA). "Most" is spelled as /məʊst/, with the "o" pronounced as a diphthong, like "oh" and "uh" together. "Show" is spelled as /ʃəʊ/, with the "o" again pronounced as a diphthong. "Me" is spelled as /miː/, with a long "e" sound. Altogether, the phrase is pronounced as /məʊst ʃəʊ miː/.
