The spelling of the word "CRMST" may seem confusing at first glance, but it is actually an acronym for the five vowels in the English language: A, E, I, O, U. When pronounced, each letter is enunciated with its corresponding phonetic sound /eɪ/, /iː/, /aɪ/, /əʊ/, and /juː/. The order of the letters follows the sequence of the alphabet, with the exception of the letter "I" being placed before "O." This unique spelling serves as a mnemonic device for students learning the order of vowels.
