'bloodbath' originates from English, specifically the words 'blood' and 'bath', where 'blood' meant 'the red liquid in the body' and 'bath' meant 'a washing or immersion in liquid'.

'bloodbath' changed from the Old English word 'blodbað' and eventually became the modern English word 'bloodbath'.

Initially, it meant 'a bath in blood', but over time it evolved into its current meaning of 'a violent event with many deaths'.
