Etymology: The term "jiggermasts" originates from maritime terminology, referring to a specific type of mast on sailing ships. The "jigger mast" is typically the smaller, aft-most mast on a vessel with multiple masts, especially those with three or more. Its name reflects its size and function in relation to the larger main and fore masts. The word "jigger" itself likely comes from nautical slang or dialectal English, where it denoted a small mechanical device or a secondary support—an idea that fits well with the smaller, auxiliary nature of the mast. The suffix "mast" is straightforward, coming from Old English "mæst," meaning the tall pole or spar that supports sails. Combined, the compound refers to a particular mast that "jigs" or assists the ship’s rigging and sail management. Historically, the use of the jigger mast became more standardized in the Age of Sail, roughly from the 17th century onward, as ship design evolved to include multiple masts for better maneuverability and speed. The jigger mast was usually rigged with smaller sails to aid in steering and balance rather than primary propulsion. The plural form, "jiggermasts," simply denotes multiple such masts, possibly in reference to a fleet of ships or a vessel with more than one auxiliary mast. Its usage is mostly confined to nautical texts and historical discussions of sailing ship architecture, retaining a specialized, technical flavor.
