In a way that is fake, fraudulent, or made to deceive by imitating something genuine.
From counterfeit (Old French contrefait, 'made in imitation') + -ly (suffix forming adverbs). The root means literally 'made against' or 'made opposite to the original.'
The word 'counterfeit' originally came from art—medieval craftsmen who created imitation works were 'making against' the authentic original, a concept that haunts art and identity even today.
