How Do You Spell CHALCOTHALLITE?
Pronunciation: [t͡ʃˈalkəθˌala͡ɪt] (IPA) 
Chalcothallite, a rare mineral composed of copper, potassium, and sodium sulfates, is a difficult word to spell due to its complicated phonetic makeup. In IPA phonetic transcription, the word is pronounced as /kælkəʊˈθælɪt/. The first syllable, "chal," sounds like "chalk" with a short "a" sound. The "coth" part is pronounced with a short "o" sound, such as in "hot." The final two syllables, "thallite," are pronounced as "thal" with a long "a" sound, followed by "lite" as in "light."
