Anchor
An anchor is a device, normally made of metal, used to connect a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin "ancora", which itself comes from the Greek ἄγκυρα ("ankura").

The term "anchor" was coined by the Golden State Dance Teachers Association in the early 1960s to clarify the difference between the "resistance" desired at the end of a West Coast Swing Pattern, and the lack of resistance caused by one version of the second set of triples taught circa 1961.
