usage note for criterion

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.

What does聽criterion mean?

A criterion is a standard or principle for judging, evaluating, or selecting something. It鈥檚 an ideal or requirement on which the judgment, evaluation, or selection is based.

The plural of criterion can be criteria or criterions, but criterions is rarely used.

A criterion is often a certain requirement that someone or something must meet in order to be considered or qualify for something. An applicant for a job may be evaluated based on several criteria, including their education, experience, and references鈥攅ach one of these standards is a criterion. Your grade in a class may be based on certain criteria, such as your test scores, your grades on homework and other assignments, and your participation in class. Similarly, a gymnast鈥檚 score is based on several criteria involving how well they performed certain moves.

The word criteria is often used with the word meet, as in Your entry meets all of our criteria for inclusion in the exhibit.聽

Sometimes, people try to use criteria as a singular noun (like how data is sometimes used), but this is generally considered not the right way to use it.

Example: We assess the candidates based on several criteria, and one criterion is that they must have at least five years of experience in a similar position.

Where does聽criterion come from?

The first records of the word criterion come from the early 1600s. It comes from the Greek krit岣梤ion, meaning 鈥渁 standard,鈥 from krit膿s, 鈥渏udge,鈥 from krinein, 鈥渢o decide.鈥 The word critic and related words like critical and criticism are based on the same root.

The word criterion is always used in the context of some kind of decision, judgment, or evaluation. But it鈥檚 not only used in official or formal situations. For example, when shopping for a new TV, you may have several criteria for selecting one that include things like how big it is and how much it costs.

The word criterion appears in the name of the Criterion Collection, a collection of films that are selected because they are thought to be important and to meet a certain standard of cinematic excellence.
