Endochone is a word that refers to a group of organic compounds. The spelling of this word is derived from its components - 'endo,' meaning 'inside,' and 'chone,' a suffix used for ketones. The correct pronunciation of endochone is [ɛn-doʊ-koh-n]. The first syllable is pronounced as 'en' with a short 'e' sound, followed by the stress on the second syllable 'do,' which is pronounced with a long 'o' sound. The 'chone' is pronounced with a long 'o' and an 'n' at the end, as in 'cone.'
