exaggerate: [16] Something that is exaggerated is literally ‘piled up’ out of all due proportion; indeed that is what it originally meant in English: ‘With their flipping and flapping up and down in the dirt they exaggerate a mountain of mire’, Philip Stubbes, Anatomy of Abuses 1583. It was not really until the 17th century that the current sense ‘overemphasize’ came to the fore, although it was already present in the word’s Latin original. This was exaggerāre, a compound formed from the intensive prefix exand aggerāre ‘pile up’ (a derivative of agger ‘heap’).
