jellyroll

the word 'jellyroll' is a transparent compound formed from two english words, 'jelly' and 'roll'. 'jelly' originates from the latin verb 'gelare', meaning 'to freeze or congeal', which evolved through old french to describe a food substance made from fruit juice and sugar that sets into a semi-solid state. 'roll' traces back to the latin 'rotula', a diminutive of 'rota' (wheel), conveying the action of turning something over on itself. the compound term, emerging in the late 19th century, logically describes the culinary process of spreading the congealed substance ('jelly') onto a flat cake and then turning it over on itself ('rolling') to create a cylindrical dessert. the slang meaning is a later, figurative extension playing on notions of sweetness and perhaps the rolling lifestyle of a vagrant.

Structure: jelly + roll jelly (from middle english 'gelly', from old french 'gelee', meaning 'a substance that congeals', of latin origin via 'gelare' - to freeze). roll (from middle english 'rollen', from old french 'roller', meaning 'to turn over and over', of latin origin via 'rotulus' - a small wheel).
