The spelling of the word "Vellma" can be explained using the International Phonetic Alphabet (IPA). The first sound is a voiced labiodental fricative /v/, followed by a diphthong /ɛl/ for the "e" sound and /m/ for the consonant sound. Finally, the last sound is another vowel sound, a low back vowel /ɑ/ , for the "a" sound. Therefore, the correct spelling of the name is "Velma," with a single "l" instead of a double "l." Pronounced correctly, it would be "VEL-muh."
