N. T.]);
1. "
that which has not only the name and semblance, but the real nature corresponding to the name" (Tittmann, p. 155; ["particularly applied to express that which is all that it pretends to be, for instance, pure gold as opposed to adulterated metal" 
Donaldson, New Crat. § 258; see, at length, Trench, § viii.]), 
in every respect corresponding to the idea signified by the name, real and true, genuine;
a. opposed to what is fictitious, counterfeit, imaginary, simulated, pretended:
