Have you ever paused mid-sentence wondering whether the plural of ox is oxes and foxes? Or maybe you wrote foxes and wondered why foxen isn’t a thing. The English language, full of strange exceptions, has its fair share of confusing plural forms.
Let’s dive deep into the plurals of ox and fox, uncover their origins, and explore why oxen and why foxes evolved the way they did. We’ll also touch on irregular plurals in English, plural formation rules, and how ancient grammar rules from Old English plural endings still influence modern usage.
The Singular Forms: Ox and Fox
Let’s start with the basics.
- Ox is a large domesticated bovine often used for heavy labor, especially in farming.
- Fox is a small, wild carnivorous mammal known for its cunning behavior and bushy tail.
Both ox and fox are common, countable nouns, which means they have plural forms and can be quantified—two oxen, five foxes, and so on.
But while they sound similar and end in -x, their plural forms are anything but alike.
How English Normally Forms Plurals
Before jumping into the specifics of ox and fox oxen and foxes, it helps to understand standard plural formation rules in English.
Most English nouns form plurals by adding:
- -s (e.g., dog → dogs)
- -es if the noun ends in -s, -sh, -ch, -x, or -z (e.g., bus → buses, dish → dishes, fox → foxes)
This rule is straightforward and widely applied. However, English has many irregular plurals that don’t follow these conventions.
Here’s a quick breakdown:
| Rule | Example |
|---|---|
| Add -s | cat → cats |
| Add -es | box → boxes |
| Change vowel | man → men |
| Add -en | child → children |
| Irregular entirely | mouse → mice |
| No change | sheep → sheep |
The Plural of Fox: Why It’s ‘Foxes
Let’s start with the easy one.
The plural of fox is foxes, and this follows the standard plural suffix -es rule. Because fox ends in the consonant -x, English adds -es for ease of pronunciation. Try saying foxs — it just doesn’t roll off the tongue naturally.
Why foxes?
Because fox fits into a class of nouns that require -es for plural clarity when ending in sibilant sounds (s, x, ch, sh, z).
Examples in Action:
- “Three foxes were spotted near the edge of the forest.”
- “Foxes are primarily nocturnal hunters.”
Other Words That Follow This Rule:
- Box → Boxes
- Witch → Witches
- Dish → Dishes
- Tax → Taxes
So while it’s common, foxes is still interesting because it exemplifies how phonetics shapes spelling in English pluralization.
The Plural of Ox: Why It’s ‘Oxen’
This is where things get fascinating.
Unlike fox, the plural of ox and fox oxen and foxes, which breaks the modern rules of plural formation entirely. So, why not just say oxes?
The Answer Lies in Old English Grammar
English once had two types of nouns:
- Strong nouns: Formed plurals with a vowel change (e.g., man → men)
- Weak nouns: Added -en to make plurals (e.g., ox → oxen)
The weak noun plural -en was common in Old English but has nearly vanished today. Oxen is one of the rare survivors.
Why oxen?
Because it descends from a time when English used -en to pluralize certain nouns of Germanic origin.
A Glimpse into History:
- Old English: oxa (singular), oxan (plural)
- Middle English: transitioned to oxen
- Modern English: preserved oxen as the standard plural
In contrast, fox was pluralized in Old English as foxas, aligning with what became the -es rule we follow today.
Oxen vs Foxes: Why Are They So Different?
So now we ask: if ox and fox are both Germanic in origin and end similarly, why oxen and not foxen?
Let’s explore:
Etymology Table: Ox vs. Fox
| Word | Language of Origin | Old English Form | Historical Plural | Modern Plural |
|---|---|---|---|---|
| Ox | Proto-Germanic | oxa | oxan | Oxen |
| Fox | Proto-Germanic | fox | foxas | Foxes |
What Changed?
- Fox followed the trend of plural simplification as English evolved.
- Ox, due to its deep cultural and agricultural importance, retained the older plural.
English began leveling its plural forms in the Middle English period (1100–1500), favoring -s or -es endings for consistency. Yet, some old forms survived due to usage frequency, religious influence, or cultural weight.
Think of children, brethren, oxen — they’ve lingered because they were too embedded to change.
English Weak vs. Strong Nouns
Understanding English weak vs strong nouns helps demystify these oddities.
Strong Nouns
- Change vowel sounds for plural.
- Example: foot → feet, goose → geese
Weak Nouns
- Add -en suffix.
- Example: child → children, ox → oxen
Most weak nouns have faded from modern English, but a few persist. These remnants preserve an older version of the language, giving it color and texture.
Why Oxen Survived but Foxen Didn’t
The short version? Language changes, but not evenly.
Reasons Why Oxen Survived:
- Institutional use (in agriculture, religion, literature)
- Symbolic value (Biblical references, formal writing)
- High frequency in early English texts
Why Foxen Didn’t:
- Less symbolic significance
- Simplified during Middle English era
- Easily adapted to newer grammar patterns
The Great Vowel Shift (1400s–1700s) and other phonetic evolutions further solidified new rules and phased out exceptions like foxen.
Common Mistakes and Misconceptions
Even native English speakers sometimes stumble over the ox plural.
Here’s what people often get wrong:
Mistakes:
- ❌ Oxes → incorrect
- ❌ Foxen → humorous or archaic, but incorrect in standard usage
- ❌ Oxen as a verb → “I will oxen the field” is not valid
Tip:
Stick with oxen for multiple oxen, and foxes for multiple foxes. No need to get creative here — the rules are already established.
Other Irregular Plurals in English
Here’s a broader look at other nouns that don’t follow the standard -s or -es pattern:
| Singular | Plural | Type |
|---|---|---|
| Man | Men | Strong |
| Woman | Women | Strong |
| Child | Children | Weak |
| Goose | Geese | Strong |
| Tooth | Teeth | Strong |
| Mouse | Mice | Strong |
| Ox | Oxen | Weak |
| Louse | Lice | Strong |
These forms are linguistic fossils — remnants of Old English grammar embedded in modern speech.
Usage in Modern English
Let’s look at how oxen and foxes appear in real-world usage.
Oxen in Modern Context:
- Still used in agriculture (e.g., in parts of Asia, Africa, and South America).
- Common in Biblical and historical texts.
- Symbolically used in idioms: “as strong as an ox”
Foxes in Modern Context:
- Frequently used in journalism, nature documentaries, literature.
- Popular idioms: “sly as a fox”, “outfoxed the competition”
Language Evolution and the Future of Irregular Plurals
Will oxen someday become oxes? Possibly not.
Why Irregulars Persist:
- Educational systems reinforce them.
- Literature preserves them.
- Some are too ingrained to change.
But language evolves. In spoken English, some irregulars are already vanishing. For instance:
- People often say “mouses” (incorrect) when referring to computer devices.
- Some say “childs” jokingly.
Still, the history of English plurals shows us that what seems strange today was once completely normal.
Final Thoughts: Oxen vs Foxes Differences Matter
So, what have we learned?
- The plurals of ox and fox follow entirely different grammatical paths.
- Foxes is formed using the standard plural suffix -es based on modern pronunciation needs.
- Oxen is a rare survivor from a time when English used Old English plural endings like -en.
- These differences reflect deep-rooted changes in English grammar, particularly in the clash between English weak vs strong nouns.
Remember:
- ✅ Ox → Oxen
- ✅ Fox → Foxes
- ❌ No such thing as foxen (except in fantasy fiction)
Understanding these quirks not only helps you use them correctly but also gives you a fascinating glimpse into the history of English plurals and why the language is the way it is today.
