criterion
Americannoun
noun
-
a standard by which something can be judged or decided
-
philosophy a defining characteristic of something
Usage
Like some other nouns borrowed from the Greek, criterion has both a Greek plural, criteria, and a plural formed on the English pattern, criterions. However, the -s plural is rarely used; the plural ending in -a is the usual form: These are the criteria for the selection of candidates. Though criteria is properly a plural noun, it is increasingly used as a singular noun, most often in speech but also occasionally in edited prose: One criteria is that the candidate must be over 18. This use of criteria as a singular noun is generally considered incorrect.
Criteria, the plural of criterion, is not acceptable as a singular noun: this criterion is not valid; these criteria are not valid
Synonym Usage
See standard.

Etymology
Origin of criterion
First recorded in 1605–15; from Greek kritḗrion “a standard,” equivalent to kri- variant stem of krī́nein “to separate, decide” + -tērion neuter suffix of means (akin to Latin -tōrium -tory 2 )
Explanation
A criterion is a standard for judging something. If you are holding a cupcake competition, your number one criterion might be the smoothness of frosting. A criterion is a category for judging, but can also be a prerequisite for an achievement. It might be an application requirement for a teaching job that you have taught already for two years. If you haven’t, then we say you haven’t "met the criterion" for job experience. Likewise, if you establish the model for something, say you deliver an exciting, profound graduation speech, we might say you "set the criterion" for future speakers.
