'lovestruck' originates from the combination of 'love' and 'struck', where 'love' refers to deep affection and 'struck' implies being hit or affected suddenly.

'lovestruck' evolved from the Old English word 'lufu' for 'love' and the Middle English 'striken' for 'struck', eventually forming the modern English word 'lovestruck'.

Initially, it meant 'hit by love', and over time it evolved into its current meaning of 'overwhelmed by feelings of love'.
