The spelling of the word "finnell" is quite interesting. According to the IPA phonetic transcription, the word is pronounced as /ˈfɪnəl/. The first syllable is pronounced as "fin" with the short "i" sound, followed by the schwa sound in the second syllable, and ending with the "l" sound. This spelling follows the English language's convention of using double letters to indicate the short vowel sound in the first syllable of a word. However, some variations of the word, like "final" and "finale," do not use double letters to indicate pronunciation.
