The word authentical is derived from the Latin word authenticus, which in turn derives from the Greek word authentikos. The Greek word authentikos means original, genuine, authoritative. Over time, this word made its way into Old French as autentique and eventually entered Middle English as authentique. Through further development in Modern English, it eventually became authentic.
