Usage note Many authors of usage guides, editors, teachers, and others feel strongly that such “absolute” words as complete, equal, perfect, and especially unique cannot be compared because of their “meaning”: a word that denotes an absolute condition cannot be described as denoting more or less than that absolute condition. However, all such words have undergone semantic development and are used in a number of senses, some of which can be compared by words like more, very, most, absolutely, somewhat, and totally and some of which cannot. The earliest meanings of unique when it entered English around the beginning of the 17th century were “single, sole” and “having no equal.” By the mid-19th century unique had developed a wider meaning, “not typical, unusual,” and it is in this wider sense that it is compared: The foliage on the late-blooming plants is more unique than that on the earlier varieties. The comparison of so-called absolutes in senses that are not absolute is standard in all varieties of speech and writing. See also a1, complete, perfect.

[C17: via French from Latin ūnicus unparalleled, from ūnus one]
usage Unique is normally taken to describe an absolute state, i.e. one that cannot be qualified. Thus something is either unique or not unique; it cannot be rather unique or very unique. However, unique is sometimes used informally to mean very remarkable or unusual and this makes it possible to use comparatives or intensifiers with it, although many people object to this use
c.1600, "single, solitary," from Fr. unique, from L. unicus "single, sole," from unus "one" (see one). Meaning "forming the only one of its kind" is attested from 1610s; erroneous sense of "remarkable, uncommon" is attested from mid-19c.
