Curious about the plural of phylum? Wondering if it’s “phyla” or “phylums”? Don’t worry, you’re not alone! Let’s explore this interesting question together and uncover the correct answer. Understanding plurals in science can be both fun and enlightening!
What is a Phylum?
A phylum is a major category in the classification of living organisms. It’s one of the broadest levels of biological classification, grouping together organisms with similar characteristics. It stands above the class and below the kingdom. Think of it as a big family that includes various species sharing certain fundamental traits. For example, the phylum Chordata includes animals with a spinal cord, like mammals, birds, fish, and reptiles. In essence, a phylum helps scientists organize and understand the vast diversity of life on Earth.

Pluralization Rules for the Words ending with “-um”
Words that end in “-um” often follow a Latin pluralization pattern, where the ending “-um” changes to “-a.” This is because many of these words come from Latin, where “-a” is the plural ending for second-declension neuter nouns.
Here Are Some Important Points About This Rule:
- Common Usage: This pattern is commonly observed in scientific and technical terms like “phylum” (plural “phyla”), “stratum” (plural “strata”), “bacterium” (plural “bacteria”), and so on.
- Exceptions Exist: Not all “-um” ending words follow this rule. Some, like “museum” and “album,” have been fully incorporated into English and take regular plurals with “-s” (e.g., museums, albums).
- Double Option: For certain words, both the Latin plural and a regular English plural are acceptable. For example, “curriculum” can be pluralized as “curriculums” or “curricula,” and “medium” can be pluralized as “mediums” or “media.”

Plural of Phylum
The plural of phylum (pronounced as “FYE-luhm”) is “phyla” (pronounced as “FYE-luh”). In this case, we change “-um” to “-a” to get “phyla.” This is a common rule for words of this type. For instance, “bacterium” becomes “bacteria” and “datum” becomes “data” when we need to talk about multiples.
Some Words ending with “-um” and their Plurals
| Word ending with “-um” | Plural Forms |
|---|---|
| Bacterium | Bacteria, Bacteriums |
| Curriculum | Curricula, Curriculums |
| Datum | Data, Datums |
| Medium | Media, Mediums |
| Stratum | Strata, Stratums |
| Museum | Museums |
Origins of the Word “Phylum”
The word “phylum” originates from the Greek term “phylon,” meaning “race” or “tribe.” In biology, it refers to a major category in the classification of living organisms, grouping together species with shared characteristics. The term “phylum” was first introduced by German biologist Ernst Haeckel in the 19th century to organize the diversity of life into broader categories. Today, it remains a crucial concept in biological taxonomy, aiding scientists in understanding the relationships among different species
