Definition of “Series”
The word “series” is a noun that can be used in both its singular and plural forms, which can sometimes be confusing. To fully understand its usage, it’s important to define both its singular and plural meanings.
The key thing to remember is that the word “series” remains the same whether it’s referring to one set of events or multiple sets of events.
Singular Definition
In its singular form, “series” refers to a sequence of related things or events arranged or happening one after the other. This could be episodes of a television show, books in a collection, games in a championship, or a sequence of numbers in mathematics.
The defining characteristic is that these elements are connected by a common theme, purpose, or characteristic. It represents a single, continuous or sequential entity.
For example, “The Crown is a popular TV series on Netflix” indicates that The Crown is one singular, continuous television program, even though it contains multiple episodes and seasons.
Plural Definition
In its plural form, “series” refers to multiple, distinct sequences of related things or events. Each “series” maintains its individual identity, but they are considered together as a group.
This could mean referring to multiple TV shows, multiple book collections, or multiple sets of sporting events that each form their own sequence. The context will determine whether you are referring to a single series or multiple series.
For example, “Netflix offers many different TV series to its subscribers” indicates that Netflix has multiple, independent TV shows available. Each show is a separate “series,” and the statement refers to the collection of these series.
Structural Breakdown
The word “series” belongs to a category of nouns in English that have the same form in both singular and plural. These nouns often derive from Greek or Latin roots.
Other examples include “species,” “news,” and “means.” The structure of the word itself, ending in “-s,” can mislead some people into automatically assuming it’s a plural form. However, its singular usage is equally valid and common.
Understanding this dual nature is essential for accurate grammar.
Because “series” maintains the same form, context becomes the primary indicator of whether it’s being used in a singular or plural sense. The verb agreement in the sentence is also a key clue.
A singular verb (e.g., “is,” “was”) indicates a singular series, while a plural verb (e.g., “are,” “were”) indicates multiple series.
Types and Categories of “Series”
The word “series” can be applied to various categories of sequences. Here are some common types:
TV Series
A TV series is a set of television program episodes, usually broadcast in a specific order, often telling a continuous story or exploring a common theme. These are often divided into seasons.
A TV series can be a sitcom, a drama, an animated show, or any other genre produced for television.
Book Series
A book series is a collection of books that are related to each other. They usually share characters, settings, or themes, and are published in a specific order.
These can be novels, non-fiction books, or even comic books. Reading them in order helps in understanding the overall narrative or concepts.
Sporting Series
In sports, a series refers to a sequence of games or matches played between two or more teams or individuals. The results of these games determine the winner of the series.
Examples include the World Series in baseball, a playoff series in basketball, or a test series in cricket.
Mathematical Series
In mathematics, a series is the sum of the terms of a sequence. It’s a fundamental concept in calculus and analysis.
Mathematical series can be finite (having a limited number of terms) or infinite (having an unlimited number of terms).

Usage Rules
Understanding the rules governing the use of “series” is essential for avoiding errors. As a noun with an unchanging form, context and verb agreement are crucial.
Singular Usage Rules
When referring to a single sequence, use a singular verb. The articles “a” or “the” often precede “series” in singular usage.
Singular pronouns like “it” can be used to refer back to the series.
For example: “The TV series Succession is highly acclaimed.”
Plural Usage Rules
When referring to multiple sequences, use a plural verb. The word “series” can be preceded by quantifiers like “many,” “several,” or “various.” Plural pronouns like “they” can be used to refer back to the series.
For example: “Netflix offers many different TV series, and they are all available for streaming.”
Exceptions and Special Cases
There are no real exceptions to the rule that “series” remains the same in both singular and plural forms. However, the context can sometimes be ambiguous.
Always pay close attention to the verb agreement and any quantifiers used in the sentence to determine whether “series” is singular or plural. Sometimes, rewriting the sentence can help to clarify the meaning.
For example, instead of saying “The series are popular,” you could say “The shows in the series are popular,” to make the plural nature clearer.
Common Mistakes
One of the most common mistakes is assuming that “series” is always plural because it ends in “-s.” This leads to incorrect verb agreement. Another mistake is using a plural form like “serieses,” which is not a word.
Always remember that the form of “series” remains constant.
Incorrect | Correct | Explanation |
---|---|---|
The TV series are good. | The TV series is good. | “Series” is singular, so it requires a singular verb (“is”). |
There is many book series available. | There are many book series available. | “Series” is plural, so it requires a plural verb (“are”). |
The serieses were interesting. | The series were interesting. | “Series” is already the plural form; “serieses” is incorrect. |
A series of events are planned. | A series of events is planned. | “A series” is singular, so the verb should be singular (“is”). |
Avoiding these common mistakes will improve the clarity and accuracy of your writing and speech.
