Dependent

Use "dependent" when the word directly modifies a noun (dependent variable, dependent child). Use "dependent on" when you mean "relies on" and must name what is relied on. When a phrase sounds like a fragment, add a linking verb or rewrite with "depending on."

Quick answer

If the adjective describes a noun that follows, omit "on." If you mean "relies on," write "dependent on + object" or use "depends on"/"depending on."

Adjective + noun: dependent variable, dependent child (no "on").
Shows reliance: The plan is dependent on funding.
Fragment fix: "Outcome dependent on X" → "The outcome is dependent on X" or "Depending on X, ...".

Core grammar rule (short)

"Dependent" = adjective. "On" = preposition. Use "dependent on + object" to name what something relies on; use "dependent" alone to modify a noun.

Quick diagnostic: Can you answer "dependent on what?" If yes, use "dependent on ...".
If the next word is a noun that the adjective describes, drop "on" (e.g., "dependent variable").

Spot-and-fix checklist

Run these checks in order; stop at the first "yes."

Is "dependent" directly modifying a following noun? If yes, keep it (no "on").
Do you mean "relies on"? If yes, add "on" and name the object.
Is the phrase a fragment (missing verb)? Add "is/are" or rewrite with "depending on" or "depends on."

Real usage: work, school and casual

Work examples: emails, reports and status updates

In formal writing use "is dependent on" or an active verb like "depends on." In short updates, "depends on" or "depending on" reads naturally.

Right: Our hiring plans are dependent on the Q4 budget.
Work - Wrong: Dependent on client feedback, update the roadmap.Work -
Right: Depending on client feedback, we'll update the roadmap.
Work - Usage: Report-safe: "Project completion is dependent on final approvals from Legal."

School examples: assignments, lab reports and recommendations

Teachers mark missing prepositions and fragments. Use "dependent" alone for technical nouns and "is dependent on" to state causes.

School - Wrong: The final grade dependent attendance and participation.School -
Right: The final grade is dependent on attendance and participation.
School - Usage: "In this experiment, the dependent variable is the reaction rate." (no "on")
School - Wrong: Dependent on your test scores you will be eligible.School -
Right: Depending on your test scores, you will be eligible.

Casual examples: texts, posts and speech

Conversation favors "depends on." For brief written messages, include "on" if it clarifies meaning; "depending on" introduces a condition.

Casual - Wrong: I'm dependent coffee in the morning.Casual -
Right: I'm dependent on coffee in the morning.
Casual - Usage: "It depends on traffic whether I'll make it."

Hyphenation, spacing and similar mistakes

Watch three adjacent pitfalls: hyphens, spacing typos, and the variant spelling "dependant."

Hyphenation: Do not write "dependent-on" as a compound. Rephrase: "factors on which it depends" or "factors that determine it."
Spacing typos: "dependenton" or "dependentthe" are always errors-restore " dependent on the " and name the object.
Spelling: "dependent" (-ent) is the standard adjective. "Dependant" (-ant) can be a noun in some British usage; follow your style guide.

Wrong: The decision is dependent-on the review.
Right: The decision is dependent on the review.
Usage note: British noun variant: "She has two dependants on her tax form."

Memory trick

Ask "dependent on what?" If you can answer the question immediately with a noun or phrase, use "dependent on ...". If the next word is the noun being described, drop "on."

FAQ

When do I use "dependent" without "on"?

When it modifies a noun directly (e.g., "dependent variable," "dependent clause"). If you mean "relies on," use "dependent on + object."

Is "dependant" correct?

"Dependent" is the standard adjective. "Dependant" is used as a noun in some British contexts to mean someone who depends on another. Follow your style guide.

When should I use "depends on" or "depending on" instead?

"Depends on" is an active verb suitable for concise statements. "Depending on" introduces a condition at the start of a clause. Use them when you want a verb rather than an adjective phrase.

How do I quickly fix a fragment like "Outcome dependent on X"?

Add a linking verb: "The outcome is dependent on X." Or write actively: "The outcome depends on X." Or make it conditional: "Depending on X, the outcome will change."

Are hyphens ever correct with "dependent on"?

No. Don't hyphenate "dependent on." If you need a compound modifier before a noun, rephrase: "factors on which it depends" or "factors that determine it."
