'abdomen' originates from Latin, specifically the word 'abdōmen', where 'abdō-' meant 'conceal' and '-men' was a suffix used to form nouns.

'abdōmen' transformed into the English word 'abdomen' through Middle English.

Initially, it meant 'belly or paunch', but over time it evolved into its current meaning of 'the part of the body containing the digestive organs'.
