Both spellings are real. Neither is simply wrong. The difference comes down to where you’re writing and, in British English specifically, what part of speech you’re using.
The Short Answer
In American English, dependent is the only standard spelling — used as both a noun and an adjective.
In British English, the two spellings split by function:
- dependent — adjective
- dependant — noun
If you’re writing for a global audience or you’re unsure which variety applies, dependent works everywhere.
What Do These Words Mean?
Both words come from the idea of relying on something or someone else.
As an adjective, the word describes a state of reliance:
- She is dependent on her morning coffee to function.
- The outcome is dependent on several factors.
- Children are dependent on adults for care.
As a noun, the word refers to a person who relies on another — usually financially. A child, an elderly parent, or a spouse who doesn’t earn an income can be someone’s dependant (or dependent, in American English).
- She listed two dependants on her tax return. (British English)
- He claimed three dependents on his tax form. (American English)
The British English Distinction
In British English, many style guides and dictionaries observe a spelling split between the adjective and the noun. The adjective keeps the -ent ending; the noun takes -ant.
This pattern follows a broader tendency in English where the same root word changes ending based on its grammatical role — similar to how adviser and advisor coexist, or how practice (noun) and practise (verb) split in British English.
In practice, though, this distinction is inconsistently applied. Many British publications use dependent for both the noun and the adjective. The -ant spelling for the noun is more common in formal and legal writing — tax forms, immigration documents, insurance policies — than in everyday prose.
So if you’re writing in British English:
- Formal/legal writing: prefer dependant for the noun
- General writing: dependent is widely accepted for both
Dependent vs Dependant in American English: One Spelling, Two Jobs
American English doesn’t make this split. Dependent handles both roles.
- He is a dependent child. (adjective)
- She has three dependents. (noun)
Major American dictionaries and style references list dependant as a British variant. It’s not considered an error in American English — just unusual.
Quick Reference
| American English | British English | |
| Adjective | dependent | dependent |
| Noun | dependent | dependant (formal) / dependent (common) |
Where the Confusion Comes From
The -ant / -ent ending pair is one of the trickier areas of English spelling. Many words follow no clear phonetic rule — both endings often sound identical when spoken. Add regional variation on top of that, and it’s easy to second-guess yourself.
The adjective/noun split in British English also isn’t taught widely outside formal grammar instruction, so even native British English speakers often aren’t certain which form to use.
Practical Advice
Writing for an American audience? Use dependent for everything.
Writing for a British audience in a formal context (legal, medical, financial)? Use dependant when referring to a person who relies on another — two dependants, list your dependants — and dependent for the adjective.
Writing for a mixed or unknown audience? Stick with dependent throughout. It’s the form least likely to raise eyebrows anywhere.
One More Note on Spelling
A common slip is writing dependant as an adjective in British English — for example, the outcome is dependant on the results. Most British style guides flag this as nonstandard. The adjective form is dependent in both varieties of English.
So the one rule that holds firm on both sides of the Atlantic: the adjective is always dependent.
