The spelling of the word "cicutine" can be explained using the International Phonetic Alphabet (IPA) transcription. The word is pronounced as /saɪˈkjuːtaɪn/. It has five syllables, with the emphasis on the second syllable "ku". The "cicu" part of the word comes from the Latin term "cicuta", meaning "hemlock". "Cicutine" refers to a toxic alkaloid found in certain plants, including hemlock. The spelling of the word is consistent with other words that use the "-ine" suffix to designate a chemical compound.
A volatile alkaloid, resembling or identical with coniine, present in water-hemlock, Cicuta virosa.
