usage Many commentators have objected to the comparison or modification (as by somewhat or very) of unique, often asserting that a thing is either unique or it is not. Objections are based chiefly on the assumption that unique has but a single absolute sense, an assumption contradicted by information readily available in a dictionary. Unique dates back to the 17th century but was little used until the end of the 18th when, according to the Oxford English Dictionary, it was reacquired from French. H. J. Todd entered it as a foreign word in his edition (1818) of Johnson's Dictionary, characterizing it as “affected and useless.” Around the middle of the 19th century it ceased to be considered foreign and came into considerable popular use. With popular use came a broadening of application beyond the original two meanings (here numbered 1 and 2a). In modern use both comparison and modification are widespread and standard but are confined to the extended senses 2b and 3. When sense 1 or sense 2a is intended, unique is used without qualifying modifiers.
The organ, the Craighead-Saunders, is a unique instrument, not only because of its lovely sound, but also because it is a nearly exact copy of a late Baroque organ built by Adam Gottlob Casparini of East Prussia in 1776. The original stands in the Holy Ghost Church in Vilnius, Lithuania.I suppose one could argue that it is the one and only copy, (i.e., that the original is not a copy), or that being only a "nearly exact copy" it had no twin, but were either of these blanched meanings really the one intended?
