shanty n.1

1856, also shanty, chantey "song with a boisterous chorus, sung by sailors while heaving or hoisting anything heavy;" probably an alteration of French chanter "to sing," from Latin cantare "to sing" (from PIE root *kan- "to sing"). Perhaps the immediate source is French chantez, imperative of chanter. The purpose was to enable them to pull or heave together in time with the song.

also gauntree, 1570s, "four-footed stand for a barrel," probably from Old North French gantier (Old French chantier, 13c., "store-room, stock-room"), from Latin cantherius "rafter, frame," also "a gelding," from Greek kanthelios "pack ass," which is related to kanthelion "rafter," of unknown origin. The connecting notion in all this seems to be framework for carrying things. Meaning "frame for a crane, etc." is from 1810. Railway signal sense attested by 1889. Derivation from tree (n.) + gawn "small bucket," an obsolete 16c. contraction of gallon, might be folk-etymology.

also shanty town, "community or settlement of mean or rough dwellings," 1836, American English, from shanty (n.1) + town.

A few miles from Williamsburg [Pennsylvania], there was a canal opening, and a little village of huts called Shantytown inhabited by the Irishmen who work on the canal. [William O'Bryan, "A Narrative of Travels in the United States of America," London, 1836. A footnote to the sentence reads, "A Shanty is a temporary dwelling, made of coarse boards just so as to shelter them from wind and rain."]

Often, as here, the name of a specific place. Several early references are to a Menominee village in Wisconsin.
