使用する際の注意点

• Percent/per cent originated as a shortening of the Latin phrase per centum, “per hundred”, and historically the use of the word as a noun (as in “half a percent” or “percents”) was regarded as an error, though such use has now become so common that it is recognized by all other major dictionaries, and a few treat the word as being only a noun. Of those which recognize non-nounal uses, most label it an adverb and many also label it an adjective though it does not meet tests of adjectivity.
