'gadget-lover' is a compound word formed from 'gadget' and 'lover'. 'Gadget' originates from the French word 'gâchette', meaning a small mechanical device or tool, and 'lover' comes from Old English 'lufian', meaning to love or cherish.

'Gadget' evolved from the French 'gâchette' to the modern English 'gadget', while 'lover' has remained relatively unchanged from Old English 'lufian'.

Initially, 'gadget' referred to small mechanical devices, but now it encompasses a wide range of electronic devices. 'Lover' has consistently meant someone who loves or is fond of something.
