The spelling of the word "extremital" may be confusing to some, but it's actually quite straightforward when you understand its phonetic transcription. According to the International Phonetic Alphabet (IPA), the word is pronounced as /ɪkˈstrɛm.ɪ.təl/. This means that the stress is on the second syllable, and the vowels are pronounced as "ih" (ɪ), "eh" (ɛ), and "uh" (ə). The "-al" at the end of the word indicates that it is an adjective, derived from the noun "extremity." Thus, "extremital" refers to something related to or resembling an extremity.
