What does criterial mean?
Criterial is a formal adjective meaning of or relating to criteria, and especially serving as a criterion — that is, functioning as one of the standards against which something is judged, classified, or tested. Where 'criterion' names the standard itself, 'criterial' describes whatever meets or embodies that standard. The word is most at home in academic discourse: philosophers debate whether a symptom is merely indicative of a condition or truly criterial of it, while psychologists investigating human categorization ask which features are criterial for belonging to a category rather than merely correlated with it. This distinction between being evidence for something and being part of its very definition gives the word much of its value. Though uncommon in everyday speech, 'criterial' offers writers a precise way to signal that a property is not just relevant but definitional — a nuance looser words like 'important' or 'relevant' cannot capture. Its rarity lends it an air of rigor suited to careful argumentation.

Etymology of criterial
Criterial derives ultimately from the Greek 'kritērion', meaning a means of judging, formed on the verb 'krinein' ('to separate, judge, decide') — the same root that yields 'critical', 'critic', and 'crisis'. The noun 'criterion' entered English in the early 17th century, borrowed via Latin; the adjective 'criterial' arose later as a straightforward derivative, first appearing in scholarly contexts. It remains a learned, academic formation with no vernacular history.
