"Fissipation" is a rare and obscure word, and its spelling might be puzzling. But it follows the standard English conventions, with a Latin root "fissus" (split) and a suffix "-ation" (process of, action of). Therefore, it is pronounced as /fɪsɪpˈeɪʃən/, with stress on the second syllable and six phonemes: /f/, /ɪ/, /s/, /ɪ/, /p/, /eɪ/. The meaning of "fissipation" is unclear, as it does not appear in most dictionaries, but it might relate to the act or result of fission, division, or cleavage.
