Which of the Following Singular and Plural Forms Are Both Correct?

When it comes to English grammar, singular and plural forms play a crucial role in communication. However, there are instances where choosing the correct form can be confusing. In this article, we will explore some common examples and discuss which forms are both correct. Additionally, we will address frequently asked questions (FAQs) related to this topic.

1. Data/Datum:
One of the most debated examples is the word “data.” In Latin, “datum” is the singular form, while “data” is the plural form. However, in modern English, “data” is often used as both the singular and plural form. For instance, “This data point is significant” and “These data points are significant” are both considered correct. Nevertheless, some individuals prefer to use “datum” for singular and “data” for plural to maintain the Latin distinction.

2. Criterion/Criteria:
The word “criterion” refers to a singular form, while “criteria” denotes its plural form. “This criterion is essential” and “These criteria are essential” are both grammatically correct. It is essential to remember that “criteria” should never be used as a singular noun.

3. Phenomenon/Phenomena:
“Phenomenon” is the singular form, while “phenomena” represents its plural form. For example, “This phenomenon is fascinating” and “These phenomena are fascinating” are both considered accurate.

4. Bacterium/Bacteria:
“Bacterium” is the singular form, while “bacteria” is the plural form. For instance, “This bacterium causes infection” and “These bacteria cause infections” are both correct.

5. Medium/Media:
“Medium” can be used as both a singular and plural form, depending on its context. When referring to a means or method of communication, “medium” is singular, as in “Television is a popular medium.” On the other hand, when referring to various forms of communication collectively, “media” is the plural form, as in “The media influences public opinion.” It is crucial to differentiate between the two usages to ensure accurate communication.
