The spelling of the word "minth" seems unusual and incorrect. However, if we take a closer look at its phonetic transcription in IPA, we will find that it is actually a possible way of writing the word "mint." The correct pronunciation of "mint" is /mɪnt/, with a short "i" sound in the first syllable and a "t" consonant at the end. Therefore, the spelling "minth" can be seen as a probable example of a common spelling mistake due to the similarity of the sounds of the letters "i" and "e."
