What’s the Plural of Phenomenon?
In English, phenomenon is a word that often appears in academic writing, scientific discussions, and everyday conversations. It refers to any observable event, fact, or occurrence, whether natural or man-made. However, when we need to talk about more than one phenomenon, the question arises: what is the plural of phenomenon?
In this article, we will explore the correct plural form of phenomenon, delve into the rules of pluralizing words of Greek origin (like phenomenon), and provide examples to help clarify it in different contexts. We will also answer common questions and give practice questions with answers to ensure that you fully understand how to use it properly.

What Is the Plural of “Phenomenon”?
The plural of phenomenon is phenomena. This is because phenomenon is a word of Greek origin, and in Greek, words ending in -on form their plural by changing -on to -a. Therefore, the correct plural form is phenomena, not phenomenons.
Why Is the Plural “Phenomena”?
Words like phenomenon that end in -on are borrowed from Greek, and these words typically follow Greek rules for pluralization. In Greek, the singular form phainomenon (which means “that which appears” or “that which is seen”) becomes phainomena in the plural.
Other similar words of Greek origin that follow this same pattern include:
- Criterion → Criteria
- Automaton → Automata
- Protozoon → Protozoa
This pattern holds because English, like many other languages, borrows words from classical languages such as Latin and Greek, and often retains the original pluralization rules.
What About “Phenomenons”?
While phenomenons might seem like a plausible plural form following regular English rules (where nouns ending in -n typically add -s or -es to become plural), it is not the correct plural for phenomenon. The word phenomenon does not follow regular English pluralization rules because it is a borrowed word from Greek, where the plural is phenomena.
However, you might occasionally see phenomenons used informally, especially in non-academic writing. Although technically incorrect, some people use phenomenons when referring to different types or categories of phenomena. This usage, however, is considered nonstandard, and phenomena remains the correct plural form in formal English.
Examples of “Phenomenon” and “Phenomena” in Sentences
Let’s look at how phenomenon and phenomena should be used in both singular and plural contexts to help clarify their correct usage.
Singular Form of “Phenomenon”:
- The Northern Lights are a natural phenomenon that attract tourists from all over the world.
(Here, phenomenon refers to one specific observable event.) - Global warming is a complex phenomenon that scientists are still trying to fully understand.
(This sentence uses phenomenon to describe a singular event or occurrence.) - Gravity is a universal phenomenon that affects all objects with mass.
(In this case, phenomenon refers to a fundamental scientific principle.)
Plural Form “Phenomena”:
- Several unexplained phenomena have been reported in the region, including strange lights and sounds.
(Here, phenomena refers to multiple unexplained events.) - The scientists studied the various phenomena associated with climate change, such as rising sea levels and increased storms.
(In this sentence, phenomena refers to various occurrences related to climate change.) - Astronomical phenomena like solar eclipses and meteor showers are often visible to the naked eye.
(This example discusses multiple observable events in the field of astronomy.)
Using “Phenomenon” and “Phenomena” in Different Tenses:
- Present Tense:
- The aurora borealis is a breathtaking phenomenon.
(Singular: phenomenon refers to one event.) - Scientists are observing several unusual phenomena in the night sky tonight.
(Plural: phenomena refers to multiple events.) - Past Tense:
- They investigated the phenomenon of spontaneous combustion.
(Singular: phenomenon refers to one event.) - The researchers documented various phenomena that occurred during the experiment.
(Plural: phenomena refers to multiple events.)
Common Questions About “Phenomenon” and Its Plural Form
Let’s address some frequently asked questions about the pluralization and usage of phenomenon.
Question 1:
Is “phenomena” always plural?
Answer:
Yes, phenomena is always plural. It is the correct plural form of phenomenon. If you are referring to a single event or occurrence, you should use phenomenon. When talking about multiple events, use phenomena.
Question 2:
Can “phenomenons” be used as a plural form?
Answer:
No, phenomenons is not the correct plural form of phenomenon in standard English. The correct plural is phenomena. Phenomenons may occasionally be used in informal or nonstandard contexts, but it is not grammatically correct.
Question 3:
Is “phenomenon” a countable noun?
Answer:
Yes, phenomenon is a countable noun. This means you can refer to one phenomenon or multiple phenomena. When discussing more than one observable event or occurrence, you should use the plural form phenomena.
Examples:
- Singular: A meteor shower is an exciting phenomenon to witness.
- Plural: Scientists have discovered several new phenomena in the field of quantum physics.
Question 4:
Are there other words like “phenomenon” that follow the same pluralization rule?
Answer:
Yes, several other words of Greek origin that end in -on follow the same pluralization rule, where the -on changes to -a in the plural. Some examples include:
- Criterion → Criteria
- A key criterion for success is hard work.
- The selection committee used several criteria to choose the winner.
- Automaton → Automata
- The mechanical automaton was a marvel of engineering.
- Early automata were used to entertain and amaze audiences.
- Protozoon → Protozoa
- A protozoon is a single-celled organism.
- Under the microscope, you can observe various protozoa in the water sample.
These words retain their Greek pluralization rules when used in English, just like phenomenon and phenomena.
Practice Questions: Using “Phenomenon” and “Phenomena” Correctly
Let’s test your understanding of how to use phenomenon and phenomena with the following practice questions.
Question 1:
Fill in the blank with the correct plural form:
The researchers studied several unusual _ during their fieldwork.
a) phenomenon
b) phenomena
c) phenomenons
Answer:
b) phenomena
Explanation: The correct plural form is phenomena. Phenomenon is singular, and phenomenons is incorrect.
Question 2:
Which sentence is grammatically correct?
a) The phenomenon of a solar eclipse never fails to amaze spectators.
b) The phenomena of a solar eclipse never fails to amaze spectators.
c) The phenomenons of a solar eclipse never fails to amaze spectators.
Answer:
*a) The phenomenon of a solar eclipse never fails to amaze spectators.
Explanation: Phenomenon is singular and correctly used here to refer to a single event. Phenomena is the plural form, and phenomenons is incorrect.

a) cactus
b) criterion
c) focus
Answer:
b) criterion
Explanation: Like phenomenon, criterion is a Greek word that forms its plural by changing -on to -a. The plural of criterion is criteria.
Singular and Plural Forms of Other Greek-Origin Words
To further understand how phenomenon fits into the broader category of Greek-origin words, let’s look at a few more examples. These words follow the same pattern, where the singular ends in -on and the plural ends in -a.
Words That Follow the “-on” to “-a” Rule:
- Phenomenon → Phenomena
- The Northern Lights are a stunning natural phenomenon.
- Several amazing phenomena were observed during the expedition.
- Criterion → Criteria
- The most important criterion for the award is innovation.
- The judges used several criteria to evaluate the contestants.
- Automaton → Automata
- The clockwork automaton amazed everyone at the fair.
- Early automata were often used in toys and displays.
These words retain their original Greek pluralization rules, making them exceptions to the usual English pluralization patterns, which typically involve adding -s or -es.
Conclusion
The plural of phenomenon is phenomena, following the Greek rule for pluralizing words that end in -on. While it might be tempting to apply regular English pluralization rules and use phenomenons, this is incorrect. Phenomena is the proper plural form and should be used in all formal writing and academic contexts.
Key Takeaways:
- The correct plural form of phenomenon is phenomena.
- Phenomenons is incorrect and should be avoided.
- Phenomenon is a countable noun, so you can refer to one phenomenon or multiple phenomena.
- Other words like criterion and automaton follow the same pluralization pattern as phenomenon.
By mastering the proper pluralization of phenomenon, you can confidently use the word in both written and spoken English, especially in academic and scientific discussions where precision matters!
