Phenomenon vs. Phenomena – What’s the Difference?

Any time a star athlete performs well in his first season, sportswriters are quick to label the player a rookie phenomenon. Sometimes they might shorten it to phenom, but the meaning stays the same.

What if there is more than one such player making headlines in a given season? Are these two players phenomenons, or phenomena? Even if there is only one, is he or she a phenomena or phenomenon?

Given these words’ origins in ancient Greek, it’s unsurprising that some writers are confused by the difference.

What is the Difference Between Phenomenon and Phenomena?

In this post, I will compare phenomenon vs. phenomena. I will use each word in at least one example sentence, so you can see it in context.

I will also show you how to use a mnemonic device to make choosing phenomenon or phenomena a little easier.

When to Use Phenomenon

definition of phenomenon definition of phenomena definitionWhat does phenomenon mean? Phenomenon is a singular noun. A phenomenon is something remarkable that happened, usually for unknown reasons or causes.

Almost anything can be called a phenomenon as long as meets these criteria; unusual weather patterns, exceptionally talented athletes, and events in space.

Here are a few more examples,

  • The airborne phenomenon was observed off the coast of Edinburgh at roughly 11pm last night.
  • A seismic phenomenon caused the tectonic plates to shift and create a new lava flow to the surface.
  • The Nationals, for all their annual contention, aren’t the Cubs, a beloved (or loathed) national phenomenon. –The Washington Post

Phenomenon is sometimes shortened to phenom, as in the phrase the rookie phenom Cody Bellinger. Either way, it means the same thing. Phenomenon has roots in ancient Greek, where the original word meant to appear or to show.

In philosophical contexts, a phenomenon is simply an observable fact or event, with no connotations of rarity or excitement.

When to Use Phenomena

To make matters even more confusing, phenomenons sometimes appears as a plural in the context of a talented individual.

In nonscientific writing, when referring to people, the plural phenomenons is accepted.
