The word "binion" is a bit confusing when it comes to spelling. The correct pronunciation is /ˈbɪn.jən/, with stress on the first syllable. The first three letters are phonetically pronounced as "bin", while the "-ion" is pronounced as "yən". This confusion is mainly due to the fact that the "-ion" suffix can have different pronunciations depending on the word. In the case of "binion", it is pronounced as "yən" because it derives from the Latin word "bini" meaning "a pair".
