the adverb "tremendously" originates from the latin verb tremere, meaning "to tremble or quake with fear". this root passed into latin and later english, forming the adjective "tremendous", which initially meant "such as to cause trembling" or "dreadful, awful". the suffix "-ous" was added to create the adjective form, literally "full of trembling". over time, the meaning weakened and hyperbolically shifted from inspiring dread to inspiring awe, eventually signifying something extraordinarily large or great. the final addition of the old english adverbial suffix "-ly" transformed it into the modern intensifier, denoting an action performed to an extreme degree, its connection to physical trembling now entirely metaphorical.
