Dependent or Dependant: Which Spelling Is Correct? (2026)

Dependent or dependant? Both spellings are real words, and the right one depends on where you write and how you use the word. In American English, “dependent” is the only spelling you need. In British English, “dependent” is the adjective and “dependant” is the traditional noun for a person who relies on someone else.

This guide acts like a grammar coach. You will get clear rules, side-by-side tables, real sentences and a short test. By the end, you will know which spelling to pick for emails, essays, tax forms and everyday chats.

What Does Dependent Mean?

“Dependent” describes something that relies on, or is controlled by, something else. It is also a noun in American English. As an adjective it means “reliant upon” or “determined by.”

• The plant is dependent on sunlight.
• Her mood was dependent on the weather.

What Does Dependant Mean?

“Dependant” is a noun. It means a person who relies on another person for support, usually money. Writers in British, Australian, Canadian and New Zealand English use it this way.

• He listed his wife and two children as dependants.
• The scheme covers employees and their dependants.

Dependent or Independent Variable With Examples

In science and maths, we always write “dependent variable.” The dependent variable is what you measure. The independent variable is what you change.

Study	Independent Variable	Dependent Variable
Sleep and test scores	Hours of sleep	Test score
Fertilizer and plant growth	Amount of fertilizer	Plant height
Price and sales	Price of a product	Number sold

Memory trick: the dependent variable depends on the independent one. Here the spelling is never “dependant,” because a variable is a thing, not a person.

Dependent or Dependant: What Is the Difference?

Feature	Dependent	Dependant
Part of speech	Adjective (and US noun)	Noun
Meaning	Relying on something	A person who relies on someone
US English	Always used	Not used
UK English	Adjective	Noun (traditional)
Example	She is dependent on her parents.	She is her parents’ dependant.

In short, “dependant” names a person, while “dependent” describes a relationship in which one thing relies on another.

When Should You Use Dependent?

Use “dependent”:

1. As an adjective in any variety of English
2. As a noun in American English
3. In science and maths (“dependent variable”)
4. In grammar (“dependent clause”)

When Should You Use Dependant?

Use “dependant” only when:

1. You write in British, Australian, Canadian or New Zealand English, and
2. You mean a person who is supported by someone else.

If you are not sure, “dependent” is the safer choice. Many modern guides say “dependent” has become accepted even as a British noun, though “dependant” was historically preferred there.

Dependent as an Adjective

As an adjective, “dependent” is followed by “on” (or “upon”). It tells us what something relies on.

• Our plan is dependent on the budget.

• Is the result dependent on luck?

Dependent as a Noun

In US English, a dependent is a person supported by someone else.

• She claimed her son as a dependent.
• Dependents may be covered by the health plan.

British writers would write “dependant” in these two sentences.

Dependent vs Dependant in British English

British English keeps two spellings:

• Dependent = adjective (“She is dependent on her income.”)
• Dependant = noun (“She has two dependants.”)

Many dictionaries now list “dependent” as an alternative spelling, but keeping the two apart is still helpful for clarity.

Dependent vs Dependant in American English

American English uses “dependent” for everything. It has done so in all contexts since at least the mid-20th century. If your reader is in the US, never use “dependant.”

Why Do Dependent and Dependant Look Different?

English has many words ending in either “-ant” or “-ent,” from the French and Latin roots behind them. Pairs like “defendant” and “descendant” kept their “-ant” form, while many others took “-ent.” Over time, British English let “dependant” mark the noun and “dependent” mark the adjective. American English dropped that split for simplicity. The words sound the same, so only spelling shows the difference.

Common Mistakes With Dependent and Dependant

• ❌ “She is dependant on her parents.” ✅ She is dependent on her parents.
• ❌ “Dependent of the weather.” ✅ Dependent on the weather.
• ❌ Using “dependant” in US writing.
• ❌ Writing “dependant variable.” ✅ Dependent variable.
• ❌ Mixing both spellings in one document.

Dependent or Dependant in Formal Writing

In formal documents, stay consistent with one English variety. For UK contracts, policies and visa forms, use “dependant” for people and “dependent” for the adjective. For US forms and reports, use “dependent” throughout. Check your style guide or your client’s preference.

Dependent or Dependant in Everyday Conversation

When you speak, the two words sound identical: dih-PEN-dent. In texts and emails, most people simply use “dependent.” If you spell it that way, few readers will complain.

Dependent in Academic Writing

Academic writing needs precision. Use:

• “dependent variable” in methods and results
• “dependent clause” in linguistics
• “dependent on” with a clear cause

For an essay with a UK audience, “dependants” is correct for people. When in doubt, follow your university’s style guide.

How to Remember the Difference

Try these tricks:

1. Ant = a person. “Dependant” ends in “-ant,” like “assistant” and “applicant,” which are people.
2. Ent = a description. “Dependent” ends in “-ent,” like “different” and “excellent,” which are describing words.
3. Safe default. “Dependent” will always work, so avoid “dependant” unless you are sure.
