1. Definition of Criterion and Criteria
Understanding the terms “criterion” and “criteria” begins with a clear definition of each, along with their grammatical classifications and functions within sentences. Both words are derived from Greek, and their correct usage is essential for maintaining grammatical accuracy and clarity in writing and speech.
1.1. Grammatical Classification
Criterion is a singular noun, referring to a single standard or principle by which something is judged or decided. Criteria, on the other hand, is the plural form of criterion, referring to multiple standards or principles. Recognizing this distinction is fundamental to using these words correctly.
Consider these examples:
- Criterion: “The main criterion for judging the competition was originality.”
- Criteria: “The criteria for selecting the scholarship recipients were academic excellence and community involvement.”
1.2. Function in a Sentence
Both “criterion” and “criteria” can function as subjects, objects, or complements within a sentence. Their role depends on the context and the intended meaning.
As subjects, they determine the verb form used in the sentence. As objects or complements, they receive the action of the verb or provide additional information about the subject.
Here are some examples illustrating their different functions:
- Subject: “The most important criterion is clarity.”
- Object: “The judges considered each criterion carefully.”
- Complement: “Clarity is the main criterion.”
- Subject: “The criteria are clearly defined in the guidelines.”
- Object: “The committee established the criteria for evaluation.”
- Complement: “Academic excellence and leadership skills are important criteria.”
1.3. Contexts of Use
“Criterion” and “criteria” are used in a variety of contexts, including academic writing, professional reports, and everyday conversations. They are particularly common when discussing evaluations, assessments, and decision-making processes.
In academic settings, they might appear in research papers, essays, and theses. In professional environments, they are often used in performance reviews, project evaluations, and strategic planning documents.
Even in everyday life, these words can be used when discussing the standards or principles used to make choices.
Examples in different contexts:
- Academic: “One criterion for a successful research paper is thoroughness.”
- Professional: “The primary criteria for promotion include performance and teamwork.”
- Everyday: “What criterion did you use to choose the restaurant?”
2. Structural Breakdown
A deeper understanding of “criterion” and “criteria” involves examining their structural elements, including the distinction between singular and plural forms and the origin of the root word.
2.1. Singular vs. Plural Forms
The most crucial aspect of using “criterion” and “criteria” correctly is recognizing that “criterion” is singular, while “criteria” is plural. Confusing these forms is a common error that can undermine the clarity and credibility of your writing.
Always ensure that the verb and any related pronouns agree in number with the noun.
Consider these examples to illustrate the difference:
- Singular: “The key criterion is relevance.”
- Plural: “The key criteria are relevance and accuracy.”
2.2. Root Word and Origin
Both “criterion” and “criteria” are derived from the Greek word “kritērion,” which means “a standard for judging.” Understanding this origin can help you remember that “criterion” refers to a single standard, while “criteria” refers to multiple standards. Many English words have Greek or Latin roots, and recognizing these origins can often aid in understanding their meanings and correct usage.
Knowing the etymology can also help prevent common misspellings and misuses. For example, being aware that “criteria” is the plural form reinforces the understanding that it should be used when referring to multiple standards or principles.

4. Usage Rules

4.1. Subject-Verb Agreement
Subject-verb agreement is a fundamental rule of grammar that requires the verb in a sentence to agree in number with its subject. Since “criterion” is singular and “criteria” is plural, the verb must be singular when used with “criterion” and plural when used with “criteria.”
Examples illustrating subject-verb agreement:

- “The criteria are relevance and accuracy.” (Plural subject, plural verb)
Incorrect examples showing the consequence of not following subject-verb agreement:

Examples:

5.3. Using Plural for Singular
