'loathing' originates from Old English, specifically the word 'lāðung,' where 'lāð' meant 'hostile or hateful.'

'lāðung' transformed into the Middle English word 'loathing,' and eventually became the modern English word 'loathing.'

Initially, it meant 'hostility or hatred,' but over time it evolved into its current meaning of 'a strong feeling of hatred or disgust.'
