Campus vs. Campuses – Which is Correct?
“Campus” is the singular noun for the grounds and buildings of a school, college, or university; “campuses” is its plural. Use campus for one location and campuses for two or more. Both spellings are correct, and the choice depends entirely on number, not meaning, pronunciation, or regional preference in context.
Campus or Campuses – Which is Correct?
Campus and campuses are both correct American English words. The difference is grammatical number: campus refers to one school or university site, while campuses refers to two or more sites.
Use campus with singular expressions such as “the campus,” “a campus,” or “one campus.” Use campuses with plural expressions such as “the campuses,” “several campuses,” or “many campuses.” The spelling changes because campus is a singular noun and campuses is its regular plural form.
The Best Trick to Remember the Difference
Use the number swap test: if you can replace the word with one site, choose campus. If you can replace it with multiple sites, choose campuses. The ending -es signals more than one campus, just as it does in words such as classes and houses.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| campus | Singular noun | The grounds and buildings of one educational institution | The campus has a new science center. |
| campuses | Plural noun | The grounds and buildings of two or more educational institutions or locations | The university operates three campuses. |
How to Use Campus
Campus is a singular countable noun. It can describe the physical grounds of a college or university, the buildings located there, or, in broader usage, the setting of an educational institution. It is also used for certain corporate, medical, and technology sites, such as a corporate campus or a hospital campus.
In formal and casual writing, use an article or another determiner when referring to one nonspecific campus: a campus, one campus, or this campus. When referring to a particular institution’s site, use the campus or a possessive form such as our campus.
Example 1: The campus offers students access to a library, gymnasium, and health center.
Example 2: She moved closer to campus to shorten her daily commute.
Example 3: The company’s new campus includes offices, laboratories, and a training facility.
What are the different forms of campus?
Campus is the singular form, and campuses is the standard plural form. The plural is pronounced with an extra syllable: camp-us-es. You can also use possessive forms: campus’s usually indicates possession by one campus, while campuses’ indicates possession by multiple campuses.
- Singular: The campus is peaceful.
- Plural: The campuses are connected by a shuttle service.
- Singular possessive: The campus’s theater recently reopened.
- Plural possessive: The campuses’ policies differ slightly.
Etymology of the word campus
Campus comes directly from Latin campus, meaning “field” or “open space.” English first used the word for the grounds of a college or university, particularly in North American English, during the eighteenth century. Its meaning later expanded to include educational, business, medical, and research complexes.
How to Use Campuses
Campuses is the plural form of campus. Use it when discussing two or more educational sites or separate locations belonging to one organization. A university may have campuses in different cities, states, or countries, while a business or medical organization may also operate several campuses.
Because campuses is plural, it normally takes plural verbs and plural determiners. For example, write “the campuses are” rather than “the campuses is,” and use expressions such as several campuses, multiple campuses, or all campuses.
Example 1: The university’s campuses are located throughout the state.
Example 2: Several campuses offer evening and weekend classes.
Example 3: The organization compared security procedures across its campuses.
What are the different forms of campuses?
Campuses is already the plural form of campus, so it does not take another plural ending. Its corresponding singular form is campus. When showing possession, use campuses’ for multiple campuses: “The campuses’ libraries share an online catalog.”
Etymology of the word campuses
Campuses is an English inflection of the Latin-derived noun campus. English forms its plural with -es, creating campuses. This ending reflects the word’s pronunciation and makes the plural easier to say than a simple -s ending.
