What does fuelled mean?
"Fuelled" is the past tense and past participle of the verb "fuel", written with a double "l" in British English (Americans spell it "fueled"). In its literal sense it describes supplying an engine, furnace, or fire with combustible material, as when an aircraft is fuelled before departure. Far more often today it appears figuratively: reporters write that a leak, a remark, or a rumour fuelled speculation, anger, or market growth — meaning that something fed and intensified it rather than merely started it. This figurative use carries a slightly dramatic connotation, suggesting momentum that builds on its own supply of energy. The word traces back through Old French to Latin "focus", meaning hearth, the centre of fire in a Roman home. Writers who want a vivid way to describe how events gather force will find few words more useful than this quietly powerful participle.

Etymology of fuelled
The verb "fuel" derives from the noun "fuel", which entered English in the early medieval period from Old French "feu" and related terms for firewood, ultimately rooted in the Latin "focus", meaning hearth or fireplace. The same Latin root gave rise to French "foyer" and to the English "focus", which shifted from hearth to optical and intellectual centre point. The doubled-letter spelling "fuelled" follows the British convention for verbs ending in "l", while American English adopted the single-"l" form "fueled".
