'ducklet' originates from the English word 'duck' with the diminutive suffix '-let', indicating a smaller or younger version.

'duck' changed from the Old English word 'duce', which meant 'diver', and eventually became the modern English word 'duck'.

Initially, 'duck' referred to the bird known for diving, and 'ducklet' evolved to specifically denote a smaller or younger version of a duck.
