1. This is one of a handful of words that give rise to strong feelings. Its primary meaning is 'having no like or equal, peculiar to an individual':
Throughout these fluctuations of fortune, Edith's unique teaching style was getting more finely honed—Medau News, 1986.
In this meaning it is regarded (like
perfect) as absolute in sense, i.e. something or someone is either unique or not unique; they cannot be described as
very unique or
more unique or
rather unique. (On the other hand, it is possible to be
nearly or
almost or
perhaps unique just as it is to be
nearly or
almost or
perhaps perfect.) This objection is philosophical rather than linguistic, and grammar caters for the logically impossible as readily as it does for the patently true. And is it not at least arguable that a person with three heads is
more unique than a person with only two? Or than a person with twelve fingers?
2. The word is derived via French from the Latin word
unicus meaning 'single, sole' and retained close links with its roots down to the 19th century, when it broke loose and became conceptually an English word, marking its independence with a developed meaning that is now the controversial one, i.e 'unusual, remarkable'. This sense is regarded as 'gradable' and is regularly qualified by
very and other intensifying adverbs:
Some design choices become so unique that they border on the eccentric and make a property difficult to sell—Chicago Tribune, 1995
I imagine that would be a fairly unique experience for you—film review website, British English 2004.
3. Its adoption in unconvincing contexts by the world of advertising and marketing, which offers
unique advantages,
challenges,
features,
flavours,
insights,
opportunities, and so on, and spins meaningless slogans such as
Hollywood's unique night life and
a unique blend of Scottish heather honey and rare old malt whisky, has done much to discredit this meaning, which is a natural one. Indeed, as so often with this type of sense development, meanings that are conventionally distinguished often shade into one another, and it is difficult to apply rules in the border areas of usage:
All these diverse atmospheres merge together beautifully to create a most delightful and unique East Lindsey market town—P. Furlong, 1989
Gavrilov was the outright winner of Moscow's Tchaikovsky Competition where jury and audience alike were bowled over by his flame-throwing technique, by the unique drive and physicality of his playing—Gramophone, 1992.
4. Meanwhile
unique continues to be used in its primary meaning, often followed by the preposition
to which identifies the object of uniqueness; an achievement or feat can be unique, so can an identifying number (which often has to be), and so can a method or technique:
Tuck stitch is one of those fabrics that almost all machine knitters recognise at once, it is so unique in its formation—Machine Knitting Monthly, 1992
Few dishes are unique to Jordan; one unique dish is mansaf, chunks of stewed lamb in a yogurt-based sauce served with rice—World Cultures, American English 2004 [Old English (up to 1150)C].
5. Because
unique is itself 'unique' in its primary meaning this will continue to be used, and it is more common than the strength of opposition to the weakened meaning might lead us to believe. But precise meanings are always vulnerable to drift, and in this case we are seeing a weakening of strength (as has happened to analogous words such as
peculiar and
similar), rather than the emergence of a distinct new meaning. If a rule is needed, prudence suggests that the weakened meaning should be used sparingly. In informal and conversational language, however, a broader range of meaning is permissible.
