early 14c., "to counterfeit" (a letter, document, etc.), from Old French forgier "to forge, work (metal); shape, fashion; build, construct; falsify" (12c., Modern French forger), from Latin fabricari "to frame, construct, build," from fabrica "workshop" (see forge (n.)). Meaning "to counterfeit" (a letter, document, or other writing) is from early 14c.; literal meaning "to form (something) by heating in a forge and hammering" is from late 14c. in English, also used in Middle English of the minting of coins, so that it once meant "issue good money" but came to mean "issue spurious (paper) money." Related: Forged; forging.
