What Is the Plural of “Rhinoceros”?
The most commonly accepted plural form of rhinoceros is rhinoceroses. However, there is also a less common plural form, rhinoceri, which is sometimes used in more formal or scientific contexts. Both forms are technically correct, but rhinoceroses is the plural that you are most likely to encounter in everyday usage.
Rhinoceroses vs. Rhinoceri
- Rhinoceroses: This is the standard plural form and follows the typical English rule of adding -es to nouns that end in -s. It is widely accepted in both British and American English.
- Rhinoceri: This form is derived from Latin, where many nouns ending in -us have a plural form that ends in -i. While grammatically correct, rhinoceri is far less common and might sound unusual to many English speakers.
In most cases, rhinoceroses is the preferred form when referring to more than one rhinoceros.
Why Are There Two Plural Forms?
The existence of two plural forms, rhinoceroses and rhinoceri, can be explained by the word’s etymology. Rhinoceros comes from the Greek words rhino (meaning “nose”) and keras (meaning “horn”). However, when the word was borrowed into Latin, it followed the rules of Latin pluralization, which often involved changing -us endings to -i in the plural form. This is why some people, especially in scientific or formal writing, might use rhinoceri.
However, English has its own rules for pluralization, and in modern English usage, the plural rhinoceroses has become the standard. This form follows the more familiar pattern seen in other English words that end in -s or -x, such as boxes, buses, and foxes.

Common Questions About “Rhinoceros” and Its Plural Forms
Let’s address some frequently asked questions surrounding the pluralization and usage of rhinoceros.
Question 1:
Is “rhinoceroses” or “rhinoceri” the correct plural form?
Answer:
Rhinoceroses is the standard and most commonly used plural form in both British and American English. Rhinoceri is a less common, Latin-based plural that you may encounter in more formal or scientific texts. However, in everyday usage, rhinoceroses is generally preferred.
Question 2:
Can I use “rhinoceri” in modern English?
Answer:
Yes, you can use rhinoceri, and it is grammatically correct. However, because it is less commonly used in modern English, it might sound unusual to some readers or listeners. If you are writing for a general audience, it’s best to stick with rhinoceroses, which is more widely understood.
Question 3:
Why do some people think “rhinoceri” is the correct plural?
Answer:
Some people might assume rhinoceri is the correct plural of rhinoceros because of the Latin origin of the word. In Latin, many nouns ending in -us have a plural form that ends in -i, such as cactus → cacti and fungus → fungi. While rhinoceri is grammatically valid, English has standardized rhinoceroses as the preferred plural form.
Question 4:
Is the word “rhinoceros” countable or uncountable?
Answer:
Rhinoceros is a countable noun. This means that you can refer to one rhinoceros or multiple rhinoceroses. When talking about more than one, you need to use the correct plural form, either rhinoceroses or rhinoceri.
Examples:
- Singular: We saw a rhinoceros at the zoo yesterday.
- Plural: We saw several rhinoceroses roaming in the savannah.
Question 5:
What is the collective noun for rhinoceroses?
Answer:
The collective noun for a group of rhinoceroses is a crash. Just like you might refer to a herd of elephants or a pride of lions, you would call a group of rhinoceroses a crash.
