"rough cabin, hut, mean dwelling," 1820, said to be from Canadian French chantier "lumberjack's headquarters," in French, "timber-yard, dock," from Old French chantier "gantry," from Latin cantherius "rafter, frame" (see gantry). Shanty Irish in reference to the Irish underclass in the U.S., is from 1928 (title of a book by Jim Tully).
mid-13c. sawer, sauere, "one whose occupation is the sawing of timber into planks, boards, etc." (as a surname from c. 1200), agent noun from saw (v.). Altered to the modern form after late 13c. by French and French-derived words in -ier (such as lawyer, bowyer, clothier).
late 15c., "floating platform of timber lashed or fastened together," from earlier meaning "rafter, beam" (c. 1300), from a Scandinavian source such as Old Norse raptr "log" (Old Norse -pt- pronounced as -ft-), Old Danish raft, related to Middle Low German rafter, rachter "rafter" (see rafter (n.1)).
In North America, rafts are constructed of immense size, and comprise timber, boards, staves, etc. They are floated down from the interior to the tide-waters, being propelled by the force of the current, assisted by large oars and sails, to their place of destination. The men employed on these rafts construct rude huts upon them, in which they often dwell for several weeks before arriving at the places where they are taken to pieces for shipping to foreign parts. [Bartlett, "Dictionary of Americanisms," 2nd ed., 1859]
late 14c., in heraldry, "a device in the shape of an inverted V," from Old French chevron "rafter; chevron" (13c.), so called because it looks like rafters of a shallow roof, from Vulgar Latin *caprione, from Latin caper "goat" (see cab); the hypothetical connection between goats and rafters being the animal's angular hind legs. Compare gambrel, also Latin capreolus "props, stays, short pieces of timber for support," literally "wild goat, chamoix."
