'orifice' originates from Latin, specifically the word 'orificium,' where 'os' meant 'mouth' and 'facere' meant 'to make.'

'orificium' transformed into the Old French word 'orifice,' and eventually became the modern English word 'orifice.'

Initially, it meant 'mouth or opening,' but over time it evolved into its current meaning of 'an opening or aperture, especially in the body.'
