'hot-headed' originates from the combination of 'hot' and 'head,' where 'hot' meant 'intense' and 'head' referred to 'mind or temperament.'

'hot-headed' changed from the Old English word 'hāt heafod' and eventually became the modern English word 'hot-headed.'

Initially, it meant 'having a fiery temperament,' but over time it evolved into its current meaning of 'prone to anger and impulsive actions.'
