Definition of Plural Only and Singular Only Nouns
Plural only nouns are nouns that exist solely in the plural form. They do not have a singular counterpart. These nouns typically refer to items or concepts that are inherently composed of multiple parts or are viewed as a collective entity. Using them in the singular form results in a grammatical error.
Singular only nouns, conversely, exist only in the singular form. They do not have a plural form (or if a plural form exists, it has a different meaning). These nouns often refer to uncountable substances, abstract concepts, or proper names. Attempting to pluralize them generally leads to incorrect grammar.
Understanding the distinction between these two categories of nouns is essential for accurate and effective communication in English. Recognizing whether a noun is plural only or singular only helps ensure correct subject-verb agreement and appropriate use of articles and quantifiers.
Structural Breakdown
The structure of plural only nouns often reflects their inherent plurality. Many plural only nouns end in “-s,” but this is not a universal rule. Some plural only nouns have irregular forms that do not follow standard pluralization patterns. The key characteristic is that these nouns are always treated grammatically as plural, regardless of the quantity they represent.
Singular only nouns, on the other hand, are always treated grammatically as singular. They typically refer to a single entity, substance, or concept.
While some singular only nouns may have plural forms (e.g., “fish” which can also be “fishes”), the plural form often has a different meaning or is used in specific contexts. Understanding the context is crucial when encountering nouns that can function as both singular and plural.
The grammatical number of a noun (singular or plural) dictates the form of the verb that agrees with it. For example, with a plural only noun, you would use a plural verb form: “The scissors are sharp.” With a singular only noun, you would use a singular verb form: “The information is accurate.”
Types and Categories of Plural Only Nouns
Clothing Items
Many items of clothing that consist of two symmetrical parts are plural only nouns. These include items worn on the legs or feet.
Tools and Instruments
Some tools and instruments that have two parts joined together are also plural only nouns.
Abstract Nouns
Certain abstract nouns that refer to ongoing processes or feelings are often plural only.
Diseases
Some diseases, especially those with multiple symptoms or affecting multiple areas of the body, are plural only nouns.
Geographical Names
Certain geographical names, particularly those referring to groups of islands or mountain ranges, are plural only.
Other Plural Only Nouns
There are various other plural only nouns that do not fit neatly into the above categories.
Types and Categories of Singular Only Nouns
Uncountable Nouns
Uncountable nouns, also known as mass nouns, refer to substances, materials, or concepts that cannot be easily counted. They typically do not have a plural form.
Proper Nouns
Proper nouns, which are names of specific people, places, or things, are generally singular only. While they can sometimes be pluralized to refer to multiple individuals or instances, their primary function is as singular identifiers.
Abstract Nouns (Singular)
Many abstract nouns that refer to qualities, concepts, or states of being are singular only. These nouns represent intangible ideas that are not easily quantified.
Collective Nouns (British English)
In British English, some collective nouns, such as “team” or “family,” can be treated as either singular or plural depending on whether the emphasis is on the group as a whole or the individual members. However, they are generally considered singular when referring to the group as a unit.

Plural Only Nouns:

Advanced Topics
For advanced learners, it’s important to understand the historical and etymological reasons behind why certain nouns are plural or singular only. Many plural only nouns have origins in Latin or Greek, where they were already plural forms.
Over time, these forms were adopted into English and retained their plural status.
Furthermore, the concept of countability can be subjective and culturally influenced. What is considered uncountable in one language or culture may be countable in another.
For example, the word “hair” is often uncountable in English, but countable in some other languages.
Additionally, the use of collective nouns can vary significantly between British and American English. In American English, collective nouns are almost always treated as singular, while in British English, they can be singular or plural depending on the context.
Finally, it is worth noting that language is constantly evolving, and the usage of plural only and singular only nouns may change over time. Some nouns that were traditionally considered singular only may gradually gain acceptance in plural form, and vice versa.
FAQ
Q1: What happens if I use a plural only noun in the singular form?
Using a plural only noun in the singular form results in a grammatical error. For example, saying “I need a scissor” is incorrect; the correct form is “I need a pair of scissors.”
Q2: How can I remember which nouns are plural only and which are singular only?
The best way to remember is through practice and exposure to the English language. Pay attention to how these nouns are used in context, and consult a dictionary or grammar guide when in doubt.
Creating flashcards or using online quizzes can also be helpful.
Q3: Are there any rules for determining whether a noun should be plural only or singular only?
There are no hard and fast rules, but certain patterns exist. Nouns referring to items with two symmetrical parts are often plural only, as are abstract nouns referring to ongoing processes.
Uncountable nouns are typically singular only.
Q4: Can a singular only noun ever be used in the plural form?
Some singular only nouns can be used in the plural form, but the meaning often changes. For example, “fish” can be pluralized to “fishes” to refer to different species of fish or to emphasize the number of individual fish.
Q5: Is it acceptable to use “less” instead of “fewer” with plural only nouns?
Traditionally, “fewer” is used with countable nouns (including plural only nouns), while “less” is used with uncountable nouns. However, in modern usage, “less” is sometimes used informally with plural nouns, particularly when referring to amounts or quantities.
It’s generally safer to use “fewer” in formal writing.
Q6: What is the difference between “news” and “a piece of news”?
“News” is a singular only noun that refers to information or reports about recent events. “A piece of news” is a way to quantify a single item of news.
You can also say “some news” to refer to multiple items of news.
Q7: Why are some diseases plural only nouns?
Some diseases are plural only because they involve multiple symptoms or affect multiple parts of the body. Examples include measles and mumps.
Q8: How do I use quantifiers with singular only nouns?
Use quantifiers like “much,” “little,” “a lot of,” “some,” or “a piece of” to describe the quantity of singular only nouns. For example, “I have much time,” “I need a little advice,” or “I received a lot of information.”
Q9: What is the difference between “custom” and “customs”?
“Custom” (singular) refers to a traditional or widely accepted way of behaving or doing something. “Customs” (plural) refers to the government agency responsible for collecting duties on imported goods and controlling the flow of goods into and out of a country.
Q10: Is “data” singular or plural?
Traditionally, “data” is the plural form of “datum” and should be used with a plural verb. However, in modern usage, “data” is often treated as a singular noun, especially in informal contexts.
In formal writing, it’s still preferable to treat “data” as plural.
Conclusion
Mastering the distinction between plural only and singular only nouns is essential for achieving grammatical accuracy and fluency in English. By understanding the definitions, structural characteristics, usage rules, and common mistakes associated with these noun categories, learners can significantly improve their writing and speaking skills.
Remember to pay close attention to the context in which these nouns are used and to consult reliable resources when in doubt.
Consistent practice and exposure to the English language are key to internalizing these grammatical concepts. By actively engaging with examples, completing exercises, and seeking clarification when needed, learners can develop a strong foundation in English grammar and communicate with confidence and precision.
Keep practicing and you will find these concepts become second nature!
