Syn. 1-3. AUTHENTIC, GENUINE, REAL, VERITABLE share the sense of actuality and lack of falsehood or misrepresentation. AUTHENTIC carries a connotation of authoritative certification that an object is what it is claimed to be: an authentic Rembrandt sketch. GENUINE refers to objects or persons having the characteristics or source claimed or implied: a genuine ivory carving.
REAL, the most general of these terms, refers to innate or actual - as opposed to ostensible - nature or character: In real life, plans often miscarry. A real diamond will cut glass. VERITABLE, derived from the Latin word for truth, suggests the general truthfulness but not necessarily the literal or strict correspondence with reality of that which it describes; it is often used metaphorically: a veritable wizard of finance.
