What is the difference between criteria and criterion?
The words criterion and criteria share the same definition: a rule, standard, or a distinguishment of quality by which something is judged. But the definition of criterion or criteria doesn’t involve “genre,” per se. Either exist as an exemplary reference to strive toward–– like a pinnacle of virtue within a niche topic.
The only significant difference between the nouns is that criterion is singular, and criteria is its nominative plural. But like any confusing set of words, this doesn’t mean English writers stick to the rules.
As explained by The New Oxford American Dictionary, it is a common mistake for English speakers to use the plural noun criteria as though it were singular. But does that make it okay?
Our trusted sources say no.
According to The American Heritage Dictionary, we should never use criteria as a singular noun, and that expressions like “this criteria” or “single criteria” are believed to be “erroneous.” Garner’s Modern English Usage also lists criteria as “a false singular for criterion,” sourcing the origins of error back to the 1950s’ (Garner 233).
But like many English words before, grammar authorities may eventually change their minds. As noted by Merriam-Webster’s Dictionary, “only time will tell whether [singular criteria] will reach the unquestioned acceptability of agenda.”
What about criteria vs. criterium?
Another source of confusion involves the noun “criterium,” which is a type of bicycle race. English writers may mistake criteria for the singular form of “criterium,” although “criterium” is singular in itself. The plural form of “criterium” is simply “criteriums,” and neither term has anything to do with criteria and criterion (Garner 234).
What does criterion mean?
The noun criterion is either ‘a rule, standard, or test that enables something to be judged or decided’ or ‘a distinguishing trait or quality.’ A derivative of criterion includes the adjective criterial, which describes something as modeling the quality of distinguishment or standardization.

What does criteria mean?
The word criteria is simply the plural form of criterion (n.), which we can then define as ‘several principles or standards’ by which something is ‘judged or decided.’ The word criterions is an alternative plural form of criterion, although editors often view it as nonstandard.
Example sentences
“For each type of move in figure skating, judges draw on a large set of criteria to determine how many points a skater earns.” –– Washington Post

*Editor’s Note: Any plural synonym and antonym of criterion may apply to criteria.
Where do the words criteria and criterion come from?
According to The Oxford Dictionary of Word Histories, the word criterion entered the English Language in the 17th century from Greek kritērion for ‘a means of judging’ (Chantrell 128). However, the word kritērion derives from kritēs (‘a judge’) and krīnein (‘to decide), both of which are roots of the word “critic.”
So what about criteria? As it turns out, the Greek language uses the -ia ending for plural suffixes of singular words that end with -ion. The same practice occurs with -a endings for Greek and Latin nouns like “ganglia,” “Mammalia,” and “paraphernalia.”
How to use criteria vs. criterion in a sentence?
When using criteria or criterion in a sentence, it’s essential to use proper subject-verb agreements:
- Singular “criterion” agrees with singular verbs.
- Plural “criteria” must agree with plural verbs.
For instance, it is incorrect to pair singular “criterion” with plural “are,” and it is improper to pair plural “criteria” with singular “is.” Let’s take a look at a few example sentences:
Correct:
“The criterion is easy.” (singular noun + singular verb)
“The criteria are easy.” (plural noun + plural verb)
The exception to the rule involves the present tense, where singular “criterion” agrees with plural verbs, and plural “criteria” agrees with singular verbs.
Correct:
“The criterion avoids state regulations.” (singular noun + plural verb)
“The criteria avoid state regulations.” (plural noun + singular verb)
Remember how The American Heritage Dictionary frowns down on phrases like “this criteria” or “single criteria“? That’s because words like “this” and “only” are singular, and they disagree with plural “criteria.” Therefore, whichever word you use before “criteria” needs to be plural.
Correct:
“The assignment’s only criterion is to navigate Google Scholar.” (singular determiner + singular noun + singular verb)
“The three criteria include software fluency for WordPress, Shopify, and Joomla.” (plural determiner + plural noun + plural verb)
Subject agreements become more tricky once sentences involve lists or multiple subjects, and not all spellcheckers catch the incorrect word. However, if you’re describing a set of standards or rules, plural “criteria” is the correct term to use.
Correct:
“He suggests the following criteria for students of Greek History: 1.) Previous proficiency in the writings of Homer; 2.) Ability to distinguish Ancient Greek figures; 3.) Proficiency in identifying significant geographical areas.”
