'heartwarming' originates from the combination of 'heart' and 'warming', where 'heart' refers to the emotional center and 'warming' implies creating warmth or comfort.

'heartwarming' evolved from the Old English word 'heorte' meaning 'heart' and 'wearmian' meaning 'to warm', eventually becoming the modern English word 'heartwarming'.

Initially, it meant 'to warm the heart', and over time it evolved into its current meaning of 'causing feelings of happiness and pleasure'.
