TOEIC Link Part 5: dependent versus dependant
Dependent and dependant differ by a single vowel, and the difference is a difference of grammar, not of meaning-family. The blank is not asking which spelling looks tidier; it is asking whether the word is doing the job of an adjective or a noun. Dependent is the adjective — it describes a state of relying on something or someone. Dependant is the noun — it names a person who relies on another for financial support, such as a child or spouse on an insurance form. Decide the part of speech and the spelling follows. For the wider set of look-alike traps, start with the commonly confused word pairs master index.
Note one wrinkle worth naming up front: in American English, dependent is often used for both the adjective and the noun, so on a US tax form you will see dependent as the person. TOEIC follows a broadly international standard where the noun dependant (with an a) is the safer, most consistently correct choice for the person being supported. When the two forms appear together as options, the a-spelling signals the noun and the e-spelling signals the adjective.
The core rule: relying (adjective) versus a person supported (noun)
- dependent = relying on, conditional on, or determined by (adjective). The bonus is dependent on quarterly results. It answers relying on what? Link dependent to reliant and conditional, and note it pairs with on (dependent on funding, dependent upon approval) and modifies a noun (a dependent clause).
- dependant = a person who relies on another for support (noun). Employees may add a dependant to the health plan. It answers which person is supported? Link dependant to beneficiary and family member, and note it is countable (two dependants, list your dependants, a dependant's allowance).
The key difference: dependent describes a condition of relying, while dependant names a person being supported. If the blank describes a state or relationship, choose dependent; if it names a person who is supported, choose dependant.
Why Part 5 likes this pair
Because the two forms are one letter apart and both trace to depend, Part 5 can offer the noun spelling in an adjective slot, or the reverse, to catch a reader who matches by sound. The strongest signal is the grammatical role: an answer that follows a linking verb and takes on is the adjective dependent, while an answer that follows an article or a number and names people is the noun dependant.
The launch date is __ on the outcome of the safety review.
A sense of "relying on" in an adjective slot needs dependent.
Staff must update the number of __ listed on their benefits form.
A sense of "people who are supported" needs dependants.
Spotting the clue
Decide first whether the word is an adjective or a noun, then confirm the spelling:
- Does the blank describe a state of relying, and does on or upon follow? → choose dependent (dependent on grants, weather-dependent, a dependent variable, financially dependent).
- Does the blank name a person who is supported, and is it countable or preceded by an article or number? → choose dependant (a dependant, three dependants, the employee's dependants, dependant coverage).
A quick test: can you put reliant or conditional in the slot? Then it is the adjective dependent. Can you put family member or person supported in the slot? Then it is the noun dependant. Because the split is by grammatical role, this pair sits alongside other one-letter traps such as born versus borne and affect versus effect.
Common Part 5 patterns
- Anything that describes relying wants dependent: dependent on approval, highly dependent on imports, a dependent clause, dependent upon market conditions, self-sufficient rather than dependent.
- Anything that names a supported person wants dependant: add a dependant, dependant benefits, the number of dependants, a spouse or dependant, dependant healthcare coverage.
Note the useful line: if on or upon follows the blank, the answer is almost always the adjective dependent; if an article, a number, or a possessive comes just before it and the sense is a person, it is the noun dependant. On the page, the vowel is the only clue that survives, so read the grammatical job rather than trust the near-identical look.
Quick reference
- dependent = relying, conditional (adjective) → think reliant, pairs with on / upon.
- dependant = a person who is supported (noun) → think family member, countable.
If the blank describes a state of relying, it is dependent; if it names a person being supported, it is dependant. Read the part of speech and this pair stops being a coin toss.
