The spelling of the word "adermia" can be explained using the International Phonetic Alphabet (IPA) phonetic transcription. The word is pronounced as /əˈdɜr.mi.ə/ with the primary stress on the second syllable. The first syllable is pronounced with the "schwa" sound, and the "r" sound is pronounced with a slight emphasis, as is common in many English words. The second syllable contains the long "e" sound and the "r" sound is slightly emphasized again. This pronunciation may vary slightly depending on regional accents or dialects.
