'crocodile' originates from the Greek word 'krokodilos', where 'krokē' meant 'pebble' and 'drilos' meant 'worm'.

'krokodilos' transformed into the Latin word 'crocodilus', and eventually became the modern English word 'crocodile'.

Initially, it referred to a 'worm of the stones', but over time it evolved into its current meaning of a large aquatic reptile.
