In English, nouns often have both singular and plural forms, and understanding their correct usage is essential for clear communication. “Criteria” and “criterion” are two such words, with “criteria” being the plural form and “criterion” being the singular form. This lesson will define each term and provide examples to clarify their correct usage.

Criterion

Definition:

Examples of use:

Criteria

Definition:

Understanding the difference between “criterion” and “criteria” is crucial for constructing grammatically correct sentences. “Criterion” is singular, denoting a single standard, while “criteria” is plural, indicating multiple standards. By using these terms accurately, one can effectively communicate assessments, evaluations, and judgment criteria in various contexts. Additionally, it’s important to note that while some sources accept “criterions” as the plural of “criterion,” “criteria” is the more widely accepted form.
