IPA: /ˈpɒlɪwɒg/
KK: /ˈpɑːlɪwɑːg/
A young frog or toad, especially in its early stage when it is still swimming and has a tail.
The pond was full of polliwogs swimming around.
The word 'polliwog' originates from Middle English 'polliwogge', which is derived from the Old English 'poliwog', meaning tadpole. The term combines 'poll' (meaning head) and 'wig' (meaning creature or animal). Thus, 'polliwog' refers to a creature with a head, specifically a tadpole before it develops into a frog.
Think of a 'head' ('poll') and a 'creature' ('wig') to remember that a polliwog is a young tadpole, a creature with a head.
