Etymology

Middle English taddepol "tadpole," from tode "toad" and polle "head"

Word Origin

A young tadpole looks like a large head with a tail. In time it will develop back legs and then front legs. Finally it will lose its tail and become a toad or a frog. Our word for this immature form of a toad or frog comes from Middle English taddepol. This word was a combination of two others, tode, meaning "toad," and polle, meaning "head."
