Chargoggagoggmanchauggagoggchaubunagungamaugg, the longest place name in the United States, is an alternative name of which object?

Lake Chaubunagungamaug, also known as Webster Lake, is a lake in the town of Webster, Massachusetts. It is located near the Connecticut border and has a surface area of 1,442 acres. Since 1921, the lake has also been known by a much longer name having 45 letters comprising fourteen syllables: Lake Chargoggagoggmanchauggagoggchaubunagungamaugg.

The exaggerated name "Lake Chargoggagoggmanchauggagoggchaubunagungamaugg" is a 45-letter alternative name for this body of fresh water, often cited as the longest place name in the United States and one of the longest in the world. Many area residents, as well as the official website of the town of Webster, consider the longer version correct.

The humorous translation is: "You fish on your side, I'll fish on my side, and no one shall fish in the middle". Both the exaggerated name and its humorous translation were apparently invented by Laurence J. Daly, editor of The Webster Times. According to Ives Goddard, Curator of Anthropology at the Smithsonian Institution, Daly created this "monstrosity" around 1921.

Spellings of the long name vary; in 2009, following six years of press reports, the local Chamber of Commerce agreed to have the spelling changed on its signs, but a 45-letter version of the name arrayed in a semicircle is still used. Webster schools use one long form of the name in various capacities.
