'puppy' originates from Middle French, specifically the word 'poupee,' where 'poupee' meant 'doll' or 'toy.'

'poupee' transformed into the English word 'puppy' in the late 15th century, eventually becoming the modern English word 'puppy.'

Initially, it meant 'a small dog or toy dog,' but over time it evolved into its current meaning of 'a young dog.'
