Usage Note: Unique may be the foremost example of an absolute term—a term that, in the eyes of traditional grammarians, should not allow comparison or modification by an adverb of degree like very, somewhat, or quite. Thus, most grammarians believe that it is incorrect to say that something is very unique or more unique than something else, though phrases such as nearly unique and almost unique are presumably acceptable, since in these cases unique is not modified by an adverb of degree. A substantial majority of the Usage Panel supports the traditional view. In our 2004 survey, 66 percent of the Panelists disapproved of the sentence Her designs are quite unique in today's fashion, although in our 1988 survey, 80 percent rejected this same sentence, suggesting that resistance to this usage may be waning. • In fact, the nontraditional modification of unique may be found in the work of many reputable writers and has certainly been put to effective use: “I am in the rather unique position of being the son, the grandson, and the great-grandson of preachers” Martin Luther King, Jr. “The creature is so unique in its style and appearance that the biologists who discovered it have given it not just its own species name … but have moved way up the classification scale and declared that it is an entirely new phylum” Natalie Angier See Usage Note at absolute.
