The word "antimonious" is spelled with four syllables: /æn.tɪ.ˈmoʊ.ni.əs/. The first syllable is pronounced with the short a sound, followed by the second syllable with the short i sound. The third syllable has a long o sound, and the fourth syllable has a schwa sound. The word is derived from the element antimony, and refers to someone who behaves in a superior or holier-than-thou manner. Its uncommon spelling can cause confusion for many, but its phonetic transcription helps to clarify its pronunciation.
