Why Are the Plurals “Irises” and “Irides”?
The reason behind these two plural forms comes down to linguistic history and the origins of the word “iris.”
Origins of the Word “Iris”
The word “iris” is derived from Latin and Greek. In Greek mythology, Iris was the goddess of the rainbow, which explains why the word “iris” has associations with color and light.
- Iris in Greek: Ἶρις (Iris), referring to the goddess.
- Iris in English: The word entered English to describe the eye’s colored portion, flowers, and, poetically, the rainbow.
When borrowed into English, the word naturally followed two paths for pluralization. For everyday usage, it conforms to typical English pluralization rules (irises), but in certain technical or literary contexts, the more classical Latin/Greek plural emerged (irides).
Understanding the Difference
| Plural Form | Usage | Context |
| Irises | Common plural form | Eyes, flowers |
| Irides | Scientific or literary usage | Optics, rainbow effects |
How Do You Spell “Irises”?
If you’re unsure how to spell it, “irises” follows regular English plural rules. Just add an -es to the end of the word “iris.”
What is an Iris?
Before diving deeper into plural forms, let’s clarify what “an iris” is.
- Eye Anatomy: In anatomy, the iris is the colored part of the human eye that controls the size of the pupil.
