The word "morrhuol" is a Welsh term for cod liver oil. Its unusual spelling can be explained through the use of the International Phonetic Alphabet (IPA), which allows us to transcribe the pronunciation of words from any language. In IPA, "morrhuol" is spelled as /mɔrhiːɔl/, with the two r's representing a rolled or trilled "r" sound and the "h" indicating a slightly breathy or aspirated "h" sound. The "u" is a long vowel, pronounced as "oo," while the "o" sounds more like "oh." Overall, the word has a musical quality to its pronunciation that reflects the beauty of the Welsh language.
