criterion

A criterion is a standard or principle for judging, evaluating, or selecting something. It’s 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—each 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’s 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. 

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.

The first records of the word criterion come from the early 1600s. It comes from the Greek kritḗrion, meaning “a standard,” from kritēs, “judge,” from krinein, “to decide.” 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’s 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.

Criterion is typically used in situations in which things are being judged or evaluated in some way. The plural criteria is even more common (since things are usually evaluated based on multiple criteria instead of just a single criterion).

The main reason I fell into fantasy was that when I was a kid, my one criterion for "book I'd probably like to read" was "is it fat enough to be used as a doorstopper so it lasts me a long time?" and fantasy novels tended to be LONG at the time so.
