Have you ever stopped mid-sentence, wondering if you should say species or specieses? You’re not alone! English has plenty of little quirks, and the word species is one of them. Whether you’re a student, a curious learner, or just someone who loves words, this guide is here to clear up the confusion.
We’ll take things step by step, using plain language and lots of examples. By the end, you’ll feel confident using the word species in both writing and conversation. Let’s dive in!
What Does “Species” Mean?
Before we talk about plurals, let’s quickly define the word.
Species is a scientific term used in biology. It refers to a group of living things plants, animals, or microorganisms that share similar features and can reproduce with each other.
- For example: Dogs belong to one species, and cats belong to another.
- In scientific classification, species is the basic unit.
So, when we say species, we’re talking about a type or group of living organisms.
What Is the Plural of Species?
Here’s the straightforward answer:
👉 The plural of species is species.
Yes, you read that right. The singular and the plural are exactly the same! You don’t add an “-s” or change the ending. It stays unchanged whether you’re talking about one group or many groups.
- Singular: This species of bird is rare.
- Plural: Several species of birds live in this forest.
It might feel odd at first, but once you get used to it, it’s actually pretty simple.
Why Doesn’t the Word Change?
Good question! Most English words form their plural by adding “-s” or “-es” (like cats or houses). But species is different because it comes from Latin.
In Latin, many words had the same form for both singular and plural. When English borrowed the word, it kept this feature. That’s why you don’t see “specieses.”
Other English words that work the same way include:
- Series (one series, two series)
- Deer (one deer, many deer)
- Fish (sometimes unchanged in plural)
So, think of species as part of this special group of unchanged plural nouns.
Is “Species” Singular or Plural?
Here’s where things can get a little tricky. The word species can be both singular and plural, depending on how you use it.
- Singular use: Refers to one group of organisms.
- Example: The panda is an endangered species.
- Plural use: Refers to more than one group of organisms.
- Example: Tropical rainforests are home to thousands of species.
How do you tell the difference? Look at the context. The verb form also gives a clue:
- This species is unique. (singular)
- These species are disappearing. (plural)
Common Mistakes People Make
Because species looks the same in both forms, it often causes confusion. Let’s clear up some common errors:
- Adding an extra “-es.”
❌ Many specieses live in the ocean.
✅ Many species live in the ocean. - Using the wrong verb.
❌ This species are found in Africa.
✅ This species is found in Africa. - Mixing singular and plural in the same sentence.
❌ A species are interesting.
✅ A species is interesting.
Remember: The word doesn’t change, but the verb does.
