The spelling of the word "most stomachical" can be a bit confusing, especially when it comes to the pronunciation. The word is pronounced /məʊst stʌmɪkəl/ and means "relating to the stomach." The use of the suffix -ical suggests that the word is an adjective formed from a noun, in this case "stomach." While it may not be a commonly used word, it is still important to understand the correct spelling and pronunciation for effective communication.
