- A student writes: 'Mon frère et ma sœur sont intelligents.' Their classmate argues the adjective should be intelligentes because sœur is the last noun mentioned. Who is correct and why?
Answer: The original student is correct: when a coordinated subject includes at least one masculine noun, the adjective takes the masculine plural form intelligents.
Whenever you see a question about adjective agreement with mixed-gender subjects in French, the key concept to recall is the default masculine plural rule: French grammar treats the masculine gender as the "unmarked" or neutral form when nouns of different genders are combined.
Here's the logic: in Mon frère et ma sœur, you have one masculine noun (frère) and one feminine noun (sœur) joined by et. Because the coordinated subject contains at least one masculine noun, the adjective describing the whole group takes the masculine plural form — intelligents. This makes the original student correct, confirming that B is the right answer.
Choice A reflects a common misconception: that adjective agreement follows the "last noun" principle, as if French grammar used proximity to decide gender. This rule simply doesn't exist in standard French. The coordinated subject is treated as a unit, not dominated by whichever noun comes last. Choice C is incorrect because while writing both forms (intelligents et intelligentes) is sometimes used in formal or inclusive writing for stylistic reasons, it is not a standard grammatical requirement — French grammar doesn't mandate splitting the adjective. Choice D introduces a false rule about predicative adjectives and proximity to the verb; predicative adjectives agree with the entire subject, not the noun nearest to être.
A handy tip: think of it like a tiebreaker rule — even one masculine noun in a list "wins," and the adjective goes masculine plural. Watch for questions that try to trick you with an all-feminine-looking list that secretly contains one masculine noun.
- Which sentence contains a correctly agreed adjective in the blank? 'Les robes que j'ai achetées sont ___.'
Answer: belles — beau has the irregular feminine form belle, and the plural feminine is belles, matching robes (feminine plural).
When French adjectives modify nouns, they must agree in both gender (masculine/feminine) and number (singular/plural) with the noun they describe. In this sentence, robes is feminine and plural, so any predicate adjective — even one appearing after sont — must reflect both of those qualities.
Beau is one of French's most important irregular adjectives. Its four main forms are: beau (masculine singular), bel (masculine singular before a vowel), beaux (masculine plural), belle (feminine singular), and belles (feminine plural). Since robes is feminine plural, the correct form is belles, making C the right answer.
Choice A is wrong because French adjectives never default to masculine singular regardless of the noun's gender — agreement is always required. Choice B (beaux) applies the correct plural logic but uses the masculine plural form, ignoring that robes is feminine. This is a classic half-right trap: the student remembered to make it plural but forgot gender. Choice D (belle) gets the feminine form right but drops the plural marker, perhaps based on the false idea that adjectives following être behave differently — they don't. Position in the sentence (attributive vs. predicate) never cancels the agreement rules.
A useful tip: whenever you see beau/belle/belles/beaux, write out all four forms in the margin of your test and match both gender and number to your noun before choosing. This irregular adjective appears frequently in French-1 exams precisely because students often remember one agreement dimension but forget the other.
- A student must complete the sentence: 'Cette actrice est très ___.' with the adjective fou. Which form is correct?
Answer: folle — fou has an irregular feminine form folle, which must be used because actrice is feminine singular.
When you see a French adjective question, your first instinct should be to identify the gender and number of the noun or subject being described — because French adjectives must agree with what they modify.
Here, actrice is feminine singular, so whatever adjective you use must also be feminine singular. The adjective fou is irregular: its feminine form is folle, not simply fou with an -e added. This makes D the correct answer — Cette actrice est très folle is grammatically proper and natural French.
Choice A is wrong because adjectives in French never stay in their base (masculine) form just because they follow très. The intensifier très has no effect on agreement rules whatsoever. Choice B contains a real French word — fol — but it's a trap. Fol is actually a special masculine form of fou used before masculine nouns beginning with a vowel or silent h (e.g., un fol espoir). It is not the feminine form. Choice C, fous, is the masculine plural form of fou. Using a plural form with a singular feminine subject like actrice is doubly wrong — it fails in both number and gender.
The key study tip here is to memorize irregular adjective pairs, because they appear frequently on French exams. A helpful group to know: fou/folle, beau/belle, nouveau/nouvelle, vieux/vieille. Notice that these adjectives also share the fol/bel/nouvel/vieil pattern before vowels. When you see an irregular adjective, don't guess by analogy — look for the specific feminine form you've memorized.
- A student writes: 'Ma sœur est grand et sportif.' Which correction properly applies adjective agreement for both adjectives?
Answer: 'Ma sœur est grande et sportive.' — both adjectives take the feminine singular form to match sœur.
Whenever you see an adjective describing a noun in French, your first job is to identify that noun's gender and number — everything else follows from there. Sœur (sister) is feminine and singular, which means every predicate adjective in the sentence must also be feminine singular.
For most adjectives, the feminine singular is formed by adding -e to the masculine base. Grand (masculine) becomes grande (feminine). Sportif follows a slightly different pattern — adjectives ending in -if change to -ive in the feminine — so sportif becomes sportive. Applying both rules correctly gives you grande et sportive, making A the right answer.
Answer B is a classic half-correction trap. It fixes grand → grande but leaves sportif unchanged, as if a consonant ending somehow exempts an adjective from agreement. It doesn't — every adjective must agree, regardless of its ending. Answer C makes the opposite error: sportive is correctly feminized, but grand is left in its masculine base form, as though one adjective per sentence is "enough." Agreement is not optional for either word. Answer D introduces a plural form (grands, sportifs) with no grammatical justification — the subject sœur is singular, so plural agreement makes no sense here. The idea that a "general quality" triggers plural is simply invented.
A good study habit: when you spot multiple adjectives in a sentence, check each one individually against the subject. Don't stop after correcting the first adjective — French requires agreement across the board, every time.
- A student wants to say 'The new students (female) are serious.' Which option correctly fills the blank? 'Les nouvelles étudiantes sont ___.'
Answer: sérieuses — the subject étudiantes is feminine plural, so the adjective takes the feminine plural form sérieuses.
When describing people or things in French, adjectives must agree in gender and number with the noun they describe — this applies whether the adjective comes before or after the noun (including after être and sont).
Here, the subject is étudiantes, which is feminine and plural. The base adjective sérieux follows a predictable pattern: drop the -eux ending, add -euse for feminine singular, and -euses for feminine plural. That gives you sérieuses — making C the correct answer. The full sentence, Les nouvelles étudiantes sont sérieuses, has every element properly agreeing in feminine plural form.
A is wrong on two counts: first, sérieux is the masculine plural form, used only when the group is male or mixed-gender. The question specifies a female group (étudiantes), so masculine forms are inappropriate here. B uses sérieuse, which is feminine but singular — it doesn't match the plural subject étudiantes. Agreement requires matching both gender and number, not just one. D presents a false rule entirely: predicative adjectives in French (those following être, sembler, paraître, etc.) are absolutely not invariable — they must still agree with the subject, just like attributive adjectives do.
A reliable study tip: when you see an adjective in a French sentence, always ask yourself two questions — What gender is the noun? and Is it singular or plural? Train yourself to check both every time, because distractors on this exam often get one right and the other wrong, as choices A and B demonstrate here.
- In the sentence 'J'ai deux petites amies fidèles,' a student claims both adjectives are wrongly placed and wrongly agreed. Which response best evaluates this claim?
Answer: The student is fully incorrect: petites correctly precedes the noun as a size adjective and is feminine plural, and fidèles correctly follows the noun and is feminine plural — both placement and agreement are right.
When tackling French adjective questions, you need to evaluate two things simultaneously: placement (before or after the noun?) and agreement (gender and number correct?). Mixing these up is a classic trap.
In French, most adjectives follow the noun, but a specific group — commonly remembered by the acronym BAGS (Beauty, Age, Goodness, Size) — typically precede it. Petit(e) is a size adjective, so placing petites before amies is exactly right. Since amies is feminine plural, petites (feminine plural of petit) is also correctly agreed. Moving to fidèles — "faithful" doesn't belong to the BAGS category, so it correctly follows the noun. And since fidèles is already the feminine plural form (the adjective is the same in masculine and feminine, but adds -s for plural), the agreement is spot on. Both adjectives are correctly placed and correctly agreed, making B the right answer: the student's claim is fully incorrect.
A is wrong because it reverses both adjectives unnecessarily — swapping petites to post-noun and fidèles to pre-noun directly contradicts French grammar rules. C is wrong because it incorrectly claims petites should follow the noun and misapplies the idea of "shared qualities" to justify fidèle in the singular — number agreement must match the noun, not the concept. D is wrong because adjectives in French must agree with their noun; leaving petites as the base form petit ignores feminine plural agreement entirely.
Your study tip: memorize BAGS adjectives cold. On French placement questions, always ask yourself first — does this adjective describe Beauty, Age, Goodness, or Size? — before deciding where it belongs.
- Choose the sentence in which the adjective blanc is used with correct agreement.
Answer: 'Il porte un chapeau blanc.' — blanc is masculine singular, agreeing with chapeau (masculine singular).
In French, adjectives must agree in gender (masculine or feminine) and number (singular or plural) with the noun they describe. When you see a question about adjective agreement, ask yourself: What is the noun's gender and number? Then check whether the adjective form matches.
The noun in choice B is chapeau, which is masculine singular. The adjective blanc is also masculine singular — its base form — making this a perfect match. This is your correct answer.
Now let's look at why the other choices fail. Choice A uses blancs, which is masculine plural, but chaussures is feminine plural — the correct form would be blanches. The distractor tries to trick you by correctly identifying that a plural is needed, but gets the gender wrong. Choice C uses blanches (feminine plural) with murs, but mur is masculine in French, so the correct form would be blancs. The explanation given — that the color is used for "light-colored objects" — is completely made up and has nothing to do with how French agreement works. Choice D claims no agreement is needed with direct objects after avoir, which is false. Fleurs is feminine plural, so the adjective must be blanches, not blanc.
A reliable study tip: always identify the noun's gender and number before choosing the adjective form. If you're unsure of a noun's gender, use context clues or look it up — gendered agreement errors are one of the most common mistakes on French grammar exams, and knowing your noun genders is the foundation of getting adjectives right every time.
- Consider the phrase 'une question difficile et intéressant.' A knowledgeable student would say this phrase is incorrect. What is the best explanation and correction?
Answer: Intéressant should become intéressante because both adjectives must agree with question, which is feminine singular; only the second adjective was left in its masculine base form.
Whenever you see a French adjective following a noun, your first instinct should be to check gender and number agreement — every adjective must match the noun it describes in both categories.
Here, the noun question is feminine singular. The adjective difficile already ends in -e, so its masculine and feminine forms look identical — no change needed. However, intéressant is the masculine singular base form. To agree with a feminine singular noun like question, it must add an -e, becoming intéressante. The corrected phrase is: une question difficile et intéressante. This is exactly what answer A describes, making it correct.
B is wrong because French agreement is never about "counting qualities" — two adjectives modifying the same noun don't trigger a plural. Each adjective independently agrees with the noun's actual gender and number. C is a double error: difficile has no reason to become plural (the noun is singular), and the claim that intéressant is exempt because it "ends in a nasal vowel" is fabricated — nasal endings don't override agreement rules. Intéressant absolutely needs an -e in the feminine. D misreads the grammar entirely; intéressant is functioning as a predicate adjective, not an adverb. Adverbs are invariable in French, but only true adverbs (like vraiment) enjoy that privilege — adjectives never do.
Study tip: When checking adjective agreement, always identify your noun's gender and number first, then ask yourself whether the adjective's written form already reflects that. Adjectives ending in -ant are a frequent trap because they look adverb-like but must still agree.
- Which of the following sentences demonstrates incorrect adjective agreement?
Answer: 'Nous avons vu des films intéressantes.' — intéressantes is feminine plural, but films is masculine plural.
In French, adjectives must agree in both gender (masculine/feminine) and number (singular/plural) with the noun they describe. When a question asks you to spot incorrect agreement, your job is to match each adjective's ending to the noun it modifies — checking both characteristics together.
Option D contains the error: films is a masculine plural noun, so any adjective describing it must also be masculine plural. The correct form would be intéressants, not intéressantes. The ending -es signals feminine plural, which clashes directly with the masculine films. This is a classic trap — intéressantes sounds natural to some learners because it's a common word, but the gender mismatch makes it grammatically wrong.
Options A, B, and C each demonstrate correct agreement. In A, heureux is already the masculine plural form (it doesn't change from masculine singular to plural, since it ends in -x), correctly matching the masculine plural enfants. In B, verte is feminine singular — formed by adding -e to the base vert — and matches the feminine singular noun robe perfectly. In C, contentes is feminine plural, matching the feminine plural amies. All three follow the rules without error.
A helpful study habit: whenever you see an adjective in a sentence, immediately identify the noun it describes, determine that noun's gender and number, then check whether the adjective's ending reflects both. In French 1, the most common trap is mismatching gender — especially with "false friends" like films, which sounds neutral but is grammatically masculine.
