Understanding the plural of iris can be tricky for many English learners and even native speakers. Whether you’re discussing the iris flower or the part of the eye, knowing which plural of iris to use in various contexts is essential. This article will break down the differences between the two common forms: irises and irides. By the end, you’ll be confident about which plural of iris to use and when.
What is the Plural of Iris?
The correct plural of iris depends on the context in which you’re using it. The most widely accepted form in casual conversation is irises. However, if you’re writing a more formal or scientific piece, especially when referring to the eye, the plural of iris becomes irides. Both forms are correct, but understanding their usage will help you avoid confusion.
Why Are the Plurals ‘Irises’ and ‘Irides’?
The reason for the two different forms of the plural of iris lies in the word’s origins. The word iris has roots in both Latin and Greek, which explains why we have the plural irides for more technical uses. On the other hand, irises follows typical English pluralization rules. So, when you’re talking about flowers, you use irises. When discussing multiple irises in the context of eyes, you often see the plural of iris as irides.
Origins of the Word ‘Iris’
To understand the different plural of iris forms, it’s helpful to look at the word’s etymology. Derived from Greek mythology, Iris was the goddess of the rainbow. This connection to color explains why the word came to refer to both the showy colorful flowers and the anatomical structure in the eye. Due to its Latin roots, the formal plural of iris is irides, but in English-speaking countries, you’re more likely to encounter irises in everyday speech.
What is an Iris?
Before we dive into the plural of iris, let’s first clarify what the term iris actually refers to. The word has two primary meanings:
- Iris Flower: A flowering plant known for its striking colors and large, vivid blooms. This flora can often be found in gardens and botanical gardens across the USA.
- Iris in the Eye: The thin circular structure within the eye that controls how much light enters by adjusting the size of the pupil.
When talking about more than one iris, the correct plural of iris depends on whether you’re referring to the flower or the anatomical structure.
Using ‘Iris’ in Sentences (Singular Usage)
Using iris in its singular form is relatively straightforward. Here are a few examples to show how the word is applied in sentences:
- “The iris in the garden bloomed early this season.”
- “Her left eye has a greenish iris.”
These examples make it clear that iris can refer to either a single flowering plant or the anatomical structure in the eye.
Using ‘Irises’ and ‘Irides’ in Sentences (Plural Usage)
The plural usage of iris introduces us to two forms: irises and irides. Here’s how to differentiate between them when constructing sentences:
Usage of “Irises”
- “The garden had several different types of irises, each more beautiful than the last.”

In these examples, the plural of iris refers to multiple iris flowers. In casual and non-technical writing, irises is the preferred form when discussing the flower.
Usage of “Irides”
