the.com/jam jar
A glass vault for summer, sealed against time by sugar and a satisfying pop.
means A glass jar with a lid, used for storing jam or other preserves — and, in Cockney rhyming slang, a car.
from "Jam" comes from an early word meaning to press or squeeze together — likely echoing the action of crushing fruit, and a cousin of the same "jam" you find in a traffic jam or a jammed door. "Jar" arrived via French jarre from Arabic jarrah, a large earthen vessel, carried into Europe along Mediterranean trade routes. Put together they name the humble pantry vessel — but in London's Cockney rhyming slang, "jam jar" cheekily means "car," the rhyme doing the work the literal sense never intended.
