If you’ve ever scratched your head wondering whether the plural of mouse is mouses or mice, you’re not alone. English grammar can be puzzling especially when technology throws in a curveball. Let’s break it all down in plain, conversational English.
What Does “Mouse” Mean Anyway?
Before jumping into plural forms, let’s first define what a mouse actually is. The word “mouse” can refer to:
- A small rodent, common in homes, fields, and scientific research labs.
- A computer device used for pointing, clicking, and scrolling.
This dual identity lies at the heart of the confusion.
Plural of Mouse: Mice or Mouses?
The correct plural usage of “mouse” depends entirely on context.
- If you’re talking about animals, the plural is mice.
- If you’re referring to computer devices, both mice and mouses are used, though mice is more common.
So, is “mouses” correct plural?
Technically, yes in computing. But in most style guides and dictionaries, “mice” is preferred, even for the tech gadget.
Let’s take a look at both forms.
Mice: The Traditional Plural
The plural “mice” is what we use for animals:
“Last night, we spotted three mice running under the sink.”
But “mice” is also used in many professional and tech contexts:
“We need to order ten wireless mice for the office.”
This dual use shows just how slippery English grammar rules can be.
Mouses: A Modern Twist
Mouses as a plural appears mostly in computing circles. It’s used to differentiate between animal vs device grammar.
For example:
“We’ve got three damaged mouses replace them ASAP.” From an IT support ticket
This usage emerged as computers became mainstream, leading to technological terminology adaptation.
Mouses definition (informal): More than one computer mouse, especially used in IT contexts to avoid confusion with rodents.
Mouse Plural Form: Why So Confusing?
This confusion exists because mouse pluralization rules don’t follow a single path:
- Mice comes from Old English noun patterns.
- Mouses arises from the need to distinguish computer terminology.
Here’s where etymology of ‘mouse’ plays a role.
Word Origin of Mouse
The word mouse comes from the Old English “mūs”, which itself stems from Proto-Germanic “mūs” and Proto-Indo-European “mūs”, both meaning the same rodent we know today.
In ancient English, many nouns changed their internal vowels to become plural this is called ablaut, seen in:
| Singular | Plural |
|---|---|
| Mouse | Mice |
| Louse | Lice |
| Goose | Geese |
| Man | Men |
| Foot | Feet |
This is why “mice” feels natural for animals but weird when talking about your desk gadgets.
Computer Mouse vs Animal Mouse
Here’s where the animal vs object semantics really starts to matter.
- A mouse (animal) is a living creature.
- A mouse (device) is an object originally named for its tail-like cord, giving rise to the nickname.
So, the mice and mouse difference goes beyond grammar it’s about meaning.
Why Is It Called a Mouse (in Tech)?
Thank Douglas Engelbart, the inventor of the first computer mouse. He coined the term because the device had a tail-like cable.
Engelbart computer invention changed how humans interact with machines. That small “mouse” revolutionized computing.
Mice in Computers: Modern Usage
Even tech companies use both forms:
- Apple uses “mice” on their website.
- Tech repair forums often refer to “mouses” when discussing multiple devices.
This shows how computer accessories grammar isn’t set in stone—it’s fluid.
