What Are the Plurals of Ox and Fox?
The plural of ox is oxen, and the plural of fox is foxes.
| Singular | Plural | Example |
| Ox | Oxen | Two oxen pulled the cart. |
| Fox | Foxes | Three foxes crossed the road. |
An ox is a bovine animal traditionally used for farm work and pulling loads. A fox is a wild mammal known for its pointed ears and bushy tail.
Although both nouns end in x, their plural forms aren’t the same. The word ox uses an older plural pattern, while fox follows a common English spelling rule.
Why Is the Plural of Ox Oxen?
The plural oxen comes from an older English pattern in which certain nouns formed their plurals with -en instead of -s or -es.
Most nouns no longer use this ending, but oxen remains a familiar example of the older pattern. The singular ox refers to one animal, while oxen refers to two or more.
Consider these sentences:
- The farmer owns one ox.
- Two oxen pulled a wooden cart.
- Several oxen stood near the barn.
Oxes isn’t the standard plural in modern English. When referring to more than one ox, use oxen.
Other irregular plurals include child → children and man → men. These words also change rather than simply adding -s.
Why Is the Plural of Fox Foxes?
The word fox forms its plural by adding -es. English commonly uses this ending for nouns that end in x, s, z, ch, or sh.
Adding only -s would produce foxs, which isn’t the standard spelling. The correct form is foxes.
For example:
- One fox was hiding behind a tree.
- Two foxes searched for food.
- Several foxes live in the surrounding woodland.
The same spelling pattern appears in other nouns:
| Singular | Plural |
| Box | Boxes |
| Tax | Taxes |
| Mix | Mixes |
| Church | Churches |
| Wish | Wishes |
| Fox | Foxes |
Unlike oxen, foxes follows a regular plural spelling pattern.
Common Mistakes With Ox and Fox
These words are easy to confuse when you assume that every noun follows the same plural rule.
| Incorrect | Correct |
| Two oxes pulled the cart. | Two oxen pulled the cart. |
| Three foxs crossed the road. | Three foxes crossed the road. |
| The farmer owns five ox. | The farmer owns five oxen. |
| We saw two fox near the fence. | We saw two foxes near the fence. |
The rule is straightforward: use oxen for more than one ox and foxes for more than one fox.
