Similarly one may ask, what is plural form of criterion?

If you want your writing to look professional, it is best to keep track of the plural criteria and the singular criterion. Criteria is the plural form of criterion. It is used when referring to more than one criterion. Criterion is singular and is used to refer to a single thing.
Can I say criterions?
Criteria is a bit of an unusual word—while it is formally considered plural, it is often used as if it were singular. Using it as singular, though, is considered nonstandard, so beware of that. Criterion is uncommon and criterions is rare, but neither are so rarely used that I would consider them obsolete.
