Definition of ‘Species’
The word “species” is a term used in biology to classify a group of living organisms that can interbreed and produce fertile offspring. It’s a fundamental unit of biological classification, ranking below genus and above subspecies. Understanding its grammatical behavior is crucial for accurate scientific communication.
In grammatical terms, “species” is a noun. What makes it unique is that its singular and plural forms are identical. This can be confusing, as most nouns in English change form to indicate plurality. However, “species” remains “species” whether you’re referring to one type of organism or many.
The word “species” functions both as a singular and plural noun. When used in the singular, it refers to one particular group of organisms. When used in the plural, it refers to multiple distinct groups of organisms. The context of the sentence usually clarifies whether it’s being used in the singular or plural sense.
Structural Breakdown
The unusual behavior of “species” stems from its Latin origin. Many Latin-derived words retain the same form in both singular and plural. This is not unique to “species,” but it’s one of the more commonly encountered examples in everyday language.
The lack of a distinct plural form means you must rely on other cues to determine whether “species” is singular or plural. These cues often include:
- Verb conjugation: Singular subjects take singular verbs (e.g., “The species *is* endangered”). Plural subjects take plural verbs (e.g., “The species *are* diverse”).
- Determiners: Words like “a,” “an,” “one,” indicate singular usage. Words like “these,” “those,” “many,” “several,” indicate plural usage.
- Context: The surrounding sentences and the overall topic often provide clues about whether you’re discussing one species or multiple species.
Understanding these cues is essential for correctly interpreting and using the word “species” in both written and spoken English. Recognizing these contextual clues ensures clear and accurate communication, especially in scientific and academic settings.
Types and Categories of Use
While the form of “species” remains the same, its usage can be categorized based on the context and the intended meaning. Understanding these categories can help clarify its role in different types of sentences.
Singular Usage
When referring to a single, specific group of organisms, “species” is used in the singular sense. This is often accompanied by singular verbs and determiners like “a” or “the.”
Plural Usage
When referring to multiple, distinct groups of organisms, “species” is used in the plural sense. This is typically accompanied by plural verbs and determiners like “these,” “those,” “many,” or “several.”
Generic Usage
Sometimes, “species” can be used in a generic sense to refer to the concept of a species in general, without specifying a particular number. In these cases, the context determines whether it’s closer to a singular or plural meaning.
Examples of Categories
- Singular: “The *species* of butterfly *is* known for its vibrant colors.”
- Plural: “The *species* of birds in this region *are* incredibly diverse.”
- Generic: “The evolution of a *species* is a complex process.”

Usage Rules and Guidelines
Using “species” correctly involves understanding a few key rules. These rules govern verb conjugation, determiner usage, and overall sentence structure. Mastering these guidelines will ensure that your writing is clear and grammatically accurate.
- Verb Agreement: The verb must agree in number with the subject. If “species” refers to one group, use a singular verb. If it refers to multiple groups, use a plural verb.
- Determiner Usage: Use singular determiners (e.g., “a,” “the,” “this”) with singular usages and plural determiners (e.g., “these,” “those,” “many”) with plural usages.
- Context Clarity: Ensure the context of your sentence makes it clear whether you’re referring to one species or multiple species. Avoid ambiguity by providing sufficient information.
It’s also crucial to be consistent in your usage throughout a piece of writing. Switching between singular and plural verb forms without a clear reason can confuse the reader.
Common Mistakes to Avoid
One of the most common mistakes is using a singular verb when referring to multiple species, or vice versa. Another frequent error is failing to provide enough context, leading to ambiguity.
| Incorrect | Correct | Explanation |
|---|---|---|
| The species are endangered. (Referring to one species) | The species is endangered. | Singular verb “is” should be used with singular “species.” |
| These species is unique. | These species are unique. | Plural verb “are” should be used with plural “species.” |
| Species is important. (Unclear context) | The study of species is important. OR Several species are important. | Provide context to clarify singular or plural usage. |
| A species are thriving. | A species is thriving. | Singular verb “is” should be used with singular “a species.” |
| Many species is native to the area. | Many species are native to the area. | Plural verb “are” should be used with plural “many species.” |
| This species are well-studied. | This species is well-studied. | Singular verb “is” used because of “this species.” |
| Those species is rare. | Those species are rare. | Plural verb “are” used because of “those species.” |
| The species, which are endangered, needs protection. | The species, which is endangered, needs protection. | Singular verb “is” used because it refers back to singular “the species.” |
By being aware of these common errors, you can avoid them in your own writing and speaking. Paying close attention to verb agreement and context is crucial for accurate usage.

Advanced Topics
For advanced learners, it’s helpful to understand the nuances of “species” in more complex contexts. This includes its use in scientific literature, discussions of taxonomy, and evolutionary biology.
In scientific writing, the term “species” is often used with specific taxonomic classifications (e.g., Homo sapiens). Understanding the rules of binomial nomenclature (the formal system of naming species) is essential for accurate scientific communication.
Discussions of speciation (the process by which new species arise) often involve complex debates about the definition of “species” itself. Different species concepts (e.g., biological species concept, phylogenetic species concept) offer varying perspectives on what constitutes a distinct species.
Furthermore, the concept of “species complex” refers to a group of closely related species that are difficult to distinguish. Understanding these complexities requires a deep knowledge of evolutionary biology and taxonomy.
Frequently Asked Questions
Here are some frequently asked questions about the plural of “species.”
- Is “species” singular or plural?
“Species” is both singular and plural. Its form doesn’t change, but the context and verb conjugation indicate whether it refers to one or multiple groups of organisms.
- How do I know if “species” is singular or plural in a sentence?
Look at the verb conjugation and the surrounding determiners. Singular verbs (e.g., “is,” “has”) and singular determiners (e.g., “a,” “the”) indicate singular usage. Plural verbs (e.g., “are,” “have”) and plural determiners (e.g., “these,” “those”) indicate plural usage.
- Can I use “specieses” as the plural form?
No, “specieses” is not a correct plural form. The correct plural form is “species.”
- What is binomial nomenclature?
Binomial nomenclature is the formal system of naming species, using a two-part name consisting of the genus and the species epithet (e.g., Homo sapiens). The genus is capitalized, and the entire name is usually italicized.
- What is a species complex?
A species complex is a group of closely related species that are difficult to distinguish, often due to recent divergence or ongoing hybridization.
- Why doesn’t “species” have a different plural form like most nouns?
The word “species” originates from Latin, and some Latin-derived words retain the same form in both singular and plural. This is a characteristic of certain Latin noun declensions.
- Does the context always make it clear whether “species” is singular or plural?
In most cases, yes. However, sometimes you may need to rephrase a sentence to avoid ambiguity if the context is unclear.
- How important is it to use ‘species’ correctly in scientific writing?
Correct usage is critical in scientific writing to ensure clarity and precision. Misusing ‘species’ can lead to confusion and misinterpretation of research findings, undermining the credibility of the work.
Conclusion
Understanding the grammar of “species” is crucial for clear and accurate communication, especially in scientific and academic contexts.
