What is the Plural of ‘Series’?

Plural of Series:  English has many rules for forming word plurals. Usually, you just add "-s" or "-es" at the end. Some words change form completely, like "man" becoming "men". A few words are even trickier because they look the same in both singular and plural forms. These are called invariant nouns. Learning these patterns can help you write more clearly and professionally. In this article, we’ll look at the history and grammar of one word in particular.

What is the plural form of Series?

You might be surprised to learn that the plural of 'series' is also 'series'. No matter if you mean one show or ten, the word stays the same. In linguistics, this is called an invariant noun or a "zero plural".

The Breakdown

Why doesn't it change?

Here is the simple logic behind why we don't say "serieses":

• Latin Roots: The word comes straight from the Latin word 'series', which is part of a group of nouns that stay the same in both singular and plural forms.
• Ease of Pronunciation: If you add another "-es" to a word that already ends with a double "s" sound (se-rees-ez), it becomes awkward and hard to pronounce.
• The "Species" Rule: The word follows the same pattern as "species". You can have one species of bird or five species of birds, but the spelling always stays the same.

Quick Examples

• Singular: "I am watching a new series on Netflix."
• Plural: "There are three different series playing at the film festival."
