"Javanine" is a rare word that refers to a type of alkaloid found in coffee plants. The spelling of this word can be explained using the International Phonetic Alphabet (IPA). The first syllable, "ja," is pronounced like the first syllable of "jam." The second syllable is pronounced "və-nēn," with the "e" representing a schwa sound. The final syllable, "-ine," is pronounced like the word "mean." While this word is not commonly used, knowing its correct pronunciation and spelling can be useful for those in the coffee industry or interested in plant alkaloids.
