Begins or starts something, typically used in formal contexts such as ceremonies or official proceedings.
From Latin 'com-' (together) and 'initiare' (to begin), through Old French 'comencier.' The word entered English in the 14th century, maintaining its formal tone associated with official beginnings and ceremonies.
While 'start' and 'begin' feel casual, 'commences' carries ceremonial weight - it's the difference between starting your car and commencing graduation. This formality makes it perfect for marking significant moments that deserve linguistic dignity.
