The spelling of the name "Muirna" is unique and can be a bit confusing when it comes to pronunciation. In IPA (International Phonetic Alphabet), it is spelled as "mɪr-nə". The first syllable "Mɪr" is pronounced like the word "mirror" without the "o" sound. The second syllable "nə" is pronounced like the word "na" with a short "uh" sound. Therefore, the correct pronunciation of "Muirna" is "mɪr-nə".
