The word "fennier" is a relatively uncommon word that is spell with two syllables: fen-ee-er. Its spelling is based on the pronunciation of the word, which is represented in the IPA phonetic transcription as /ˈfɛniər/. The use of the doubled "n" in the middle of the word helps to indicate that the first syllable is stressed, while the "-ier" ending creates the comparative form (i.e. more "fenny" or pertaining to fen or marshland). Despite its relative obscurity, "fennier" can be a useful word in certain contexts, especially for those studying environmental or ecological topics.
