'bile-related' originates from the word 'bile,' which comes from Latin 'bilis,' meaning 'bile' or 'anger.' The suffix '-related' is used to indicate association or connection.

'Bile' changed from the Latin word 'bilis' and eventually became the modern English word 'bile.'

Initially, 'bile' referred to the bodily fluid, but it also took on a metaphorical meaning of 'anger' or 'bitterness.'
