'abdomen' originates from Latin, specifically the word 'abdomen', where 'abdo-' meant 'to hide' and '-men' was a suffix used in forming nouns.

'abdomen' changed from the Latin word 'abdomen' and eventually became the modern English word 'abdomen'.

Initially, it meant 'the belly or paunch', but over time it evolved into its current meaning of 'the part of the body between the chest and pelvis'.
