MAELSTROM

Maelstrom comes from an early Dutch proper noun that is a combination of the verb malen ("to grind") and the noun stroom ("stream"). The original Maelstrom, now known as the Moskstraumen, is a channel located off the northwest coast of Norway that has dangerous tidal currents and has been popularized among English speakers by writers such as Edgar Allan Poe and Jules Verne (whose writing was widely translated from French) in stories exaggerating the Maelstrom's tempestuousness and transforming it into a whirling vortex. Maelstrom entered English in the 16th century and was soon applied more generally in reference to any powerful whirlpool. By the mid-19th century, it was being applied figuratively to things or situations resembling such maelstroms in turbulence or confusion.

HABERDASHER

At various times throughout its history, the term haberdasher has referred to a dealer of hats or caps, a seller of notions (sewing supplies, such as needles and thimbles), and apparently (perhaps somewhat coyly) to a person who sells liquor. Nowadays, with hats not being as fashionable as they once were, the word mostly is applied generally as a clothing outfitter for men, with haberdashery referring to the establishment or the goods sold there. Haberdasher derives via Middle English from hapertas, an Anglo-French word for a kind of cloth, as does the obsolete noun haberdash, which once meant petty merchandise or small wares.
