tadpole

Etymology

It is formed from Middle English tadde (“toad”) + polle (“head”),^{[2][3][4][5][6]} first recorded as taddepol;^[5][6] the first part is a form of toad, from Old English tādiġe,^[7][8] and the second is poll in its old sense "head".^[2][7][9] The name thus means "toad-head", from the large head of the young animal.^[9][8][10] The OED notes that the second element has been doubted because the name seems inappropriate, but compares the dialect synonym pollhead, in Scots powheid,^[2] which is pol-hed in Middle English, recorded for a tadpole from about 1250.^[4][7]

Earliest recorded meaning

A worm or caterpillar: about 1450, glossing Latin brucus in a Latin–English glossary; another, before 1500, uses it for lumbricus.^[4][7] Barnhart dates the word to probably before 1475,^[5] and the OED's first record, before 1500, is already for the larva of a frog or toad.^[2]

Semantic evolution

The earliest uses gloss Latin words for creeping creatures such as caterpillars and earthworms,^[7][4] but by about 1500 the word meant the larva of a frog or toad, from hatching until it loses its gills and tail.^[2] Shakespeare used it figuratively in 1594 in Titus Andronicus, and in King Lear Poor Tom "eats the toad and the tadpole", as Johnson (1755) quoted.^[2][11] In the 19th century it was extended to the tailed larva of a tunicate (1880) and, in the United States, to the hooded merganser, a duck with a large-looking head (1891).^[2] American slang used Tadpoles as a nickname for people from Mississippi from 1845.^[12] Other English names for the animal include pollywog, from poll and wiggle.^[13]
