- Pour conjuguer « croire » à l'imparfait à la troisième personne du pluriel, un étudiant doit d'abord trouver le bon radical. Sachant que le présent de « croire » est : je crois, tu crois, il croit, nous croyons, vous croyez, ils croient — quelle est la forme correcte de l'imparfait ?
Answer: croyaient — radical « croy- » issu de « nous croyons » (en retirant « -ons ») + terminaison « -aient »
When forming the imparfait in French, the golden rule is this: always build your stem from the nous form of the present tense, then drop the -ons ending. This rule works for virtually every verb in the language, including irregular ones like croire.
For croire, the nous present-tense form is nous croyons. Strip away -ons, and you're left with the stem croy-. From there, attach the imparfait endings: -ais, -ais, -ait, -ions, -iez, -aient. For the third person plural (ils/elles), that gives you croyaient — making D the correct answer and the one that completes the literary sentence naturally: les enfants croyaient que la lune les suivait.
Now let's look at the traps. A (croyiaient) uses the right stem croy- but invents a non-existent "reinforced" ending -iaient. No such ending exists in French — the standard third-person plural imparfait ending is simply -aient. B (croient) makes two errors at once: it pulls the stem from ils croient instead of nous croyons, and it uses the present-tense ending -ent rather than any imparfait ending at all — this is just the present tense disguised as an answer. C (croiaient) gets the ending right (-aient) but still uses the wrong stem croi- from ils croient, which is a very common mistake when students forget to anchor their stem to the nous form.
Study tip: Anytime you need the imparfait, write out nous [verb] first and circle everything before -ons — that stem is your foundation for all six imparfait forms.
- Lequel des étudiants a raison, et quelle est la justification correcte ?
Answer: L'étudiant A a raison — le radical de l'imparfait provient de « nous voyons » (non de « je vois »), ce qui donne « voy- » + « -ais » = « voyais »
Whenever you encounter a question about forming the imparfait in French, the single most important rule to remember is this: the imparfait stem comes from the nous form of the present tense, not from je, tu, or any other person.
Here's how it works: take the present tense nous form, drop the -ons ending, and what remains is your imparfait stem. For « voir », the nous form is « nous voyons ». Remove -ons, and you get « voy- ». Then add the standard imparfait endings (-ais, -ais, -ait, -ions, -iez, -aient), giving you « je voyais », « tu voyais », etc. This rule applies to virtually all French verbs — regular and irregular alike — with only one true exception: être, whose imparfait stem is « ét- » (j'étais).
This confirms that B is correct: Étudiant A has the right answer, and the justification is the nous-form rule.
A is wrong because it describes the rule incorrectly — using the je form of the present to build the imparfait stem is not how French conjugation works. Applying « je vois → voi- » would produce the unnatural and incorrect form « je voiais », which no French speaker uses.
C is wrong because « voiais » is never an acceptable form in any register of French. There are no "two acceptable stems" for voir at the imparfait.
D is wrong because « je veyais » does not exist in modern French. While Latin roots are historically interesting, French conjugation rules don't derive directly from Latin stems in that way.
Study tip: Memorize this shortcut — nous form minus -ons = imparfait stem — and it will work for nearly every verb you encounter on this exam.
- Considérez le verbe « appeler ». Au présent, la conjugaison est : j'appelle, tu appelles, il appelle, nous appelons, vous appelez, ils appellent. En appliquant correctement les règles de l'imparfait, quelle est la forme correcte pour « ils » ?
Answer: appelaient — radical « appel- » (de « nous appelons ») + terminaison « -aient », sans doublement du « l »
When forming the imparfait in French, there's one golden rule: take the nous form of the present tense, drop the -ons ending, and add the imparfait endings (-ais, -ais, -ait, -ions, -iez, -aient). This rule applies universally — even to verbs with spelling irregularities in their present tense conjugations.
For "appeler," the nous present form is nous appelons. Strip off -ons and you get the imparfait stem: appel-. Add the ils/elles ending -aient, and you arrive at appelaient — option D, the correct answer.
Here's where the traps come in. Options A and B both build the stem from the ils present form ("ils appellent"), which features a doubled "l." This is the core misconception — the doubled "l" in appellent exists only to maintain the correct pronunciation in certain present tense forms (je, tu, il, ils), but it does not carry over into the imparfait, because the imparfait stem always comes from nous. Option B takes this error even further by producing three consecutive "l"s (appelllaient), which isn't a real French word. Option C invents a completely false rule — that the doubled "l" transforms into an accent grave (appèlaient) at the imparfait. No such transformation exists; accents and consonant doublings are separate spelling mechanisms.
Your study tip: whenever you encounter a verb with present-tense spelling changes (doubled consonants, accent shifts), always anchor your imparfait stem to nous appelons — never to je, il, or ils forms. The nous form is your reliable base every time.
- Si l'étudiant applique mécaniquement la règle du professeur au verbe « être » (nous sommes → som- + terminaisons), quelle forme obtient-il pour « je », et cette forme est-elle correcte en français moderne ?
Answer: Il obtient « somais », qui est incorrect — la règle du professeur ne s'applique pas à « être » car son imparfait correct est « j'étais », avec le radical irrégulier « ét- »
When tackling questions about French verb conjugation, it helps to distinguish between the general rule and its exceptions. The imparfait rule your professor describes — take the nous present form, drop -ons, add imparfait endings (-ais, -ais, -ait, -ions, -iez, -aient) — works beautifully for almost every French verb. The catch is "presque tous" doesn't mean "tous."
For être, applying the rule mechanically gives you: nous sommes → drop -ons → som- → add -ais → somais. That's exactly what option C identifies. However, "être" is one of French's most irregular verbs, and its imparfait uses the completely different radical ét-, giving you j'étais, tu étais, il était, etc. This radical doesn't appear anywhere in the present tense conjugation — it's historically derived from Latin and must simply be memorized.
A is wrong because it claims "somais" is actually correct, which it isn't — no native speaker or grammar authority accepts this form. B introduces the invented idea of doubling the m in "som-," which has no grammatical basis in French phonology or spelling rules. D fabricates a hybrid "étomais" form that doesn't exist anywhere in French grammar — there's no mechanism that blends radicals this way.
The correct answer is C: the mechanical application yields "somais," but the true imparfait of "être" is "j'étais."
Study tip: Memorize the imparfait of être and avoir separately — they're the two verbs most likely to appear as exceptions in rule-based questions exactly like this one.
- Parmi les formes suivantes, laquelle est correctement conjuguée à l'imparfait de la deuxième personne du pluriel (vous) ?
Answer: pouvoir → « vous pouviez » — radical « pouv- » issu de « nous pouvons » (en retirant « -ons ») + terminaison « -iez » de l'imparfait pour la deuxième personne du pluriel
When conjugating verbs at the imparfait, you follow a reliable two-step formula: take the nous form of the present tense, drop the -ons ending to get the radical, then add the imparfait endings (-ais, -ais, -ait, -ions, -iez, -aient). For vous, the ending is always -iez.
Choice C does exactly this. "Pouvoir" gives us nous pouvons → radical pouv- → add -iez → vous pouviez. This is perfectly correct and demonstrates the standard method.
Choice A contains a subtle but important error. "Prendre" at the nous form is nous prenons, which gives the radical pren-, not "prend-." The infinitive's final "d" is irrelevant here — you must always derive the radical from the nous present, not the infinitive itself. The correct form would be vous preniez.
Choice B is wrong on two counts. "Vous voulez" is simply the present tense form of "vouloir," not the imparfait. The ending -ez belongs to the present, and the explanation confuses present and past tenses entirely. The correct imparfait form is vous vouliez.
Choice D contains a misleading explanation. The radical from nous venons is ven-, not "veni-." The ending -iez already contains the "i" — you don't add an extra one. The description of "adding a supplementary i before -ez" is confused and incorrect. The correct form is simply vous veniez.
Your go-to strategy: always build your imparfait radical from the nous present tense, never from the infinitive, and remember that -iez is the complete ending for vous — no extras needed.
- Un étudiant conjugue le verbe « commencer » à l'imparfait. Il sait que les verbes en « -cer » nécessitent parfois une cédille. À quelles personnes de l'imparfait faut-il ajouter la cédille sous le « c » de « commencer », et pourquoi ?
Answer: À toutes les personnes sauf « nous » et « vous », car les terminaisons « -ions » et « -iez » commencent par « i », ce qui rend le « c » naturellement doux, tandis que les autres terminaisons commencent par « a », nécessitant la cédille
Whenever you see a question about verbs ending in -cer in French, the key concept to focus on is phonetic consistency — French spelling rules exist to preserve pronunciation, not merely for tradition.
The verb commencer contains a "c" that must always sound soft (like an "s"). In French, "c" is naturally soft before the vowels e, i, and y, but becomes hard (like a "k") before a, o, and u. The cédille (ç) exists specifically to force the soft sound before those "hard" vowels. At the imparfait, all conjugations take endings beginning with -a (-ais, -ait, -aient) except nous and vous, whose endings are -ions and -iez — both starting with "i," which already makes the "c" soft naturally. Therefore, B is correct: the cédille is needed for je, tu, il/elle, ils/elles (→ commençais, commençait, commençaient) but not for nous commencions or vous commenciez.
A is wrong because the cédille is not a fixed etymological feature — it's applied selectively based on the following vowel, never blindly to every form. C is wrong because the rule has nothing to do with the "length" of endings; it depends entirely on which vowel follows the "c." D is wrong because the cédille absolutely appears in past tenses like the imparfait — this is a common misconception that limits the rule incorrectly to the present tense.
A handy tip: whenever a -cer verb precedes the vowels a, o, u, add the cédille. Before e, i, y, no cédille is needed.
- Quelle est la forme correcte de l'imparfait pour la phrase « Nous ___ (manger) dans ce restaurant chaque vendredi » ? Attention : ce verbe appartient à un groupe qui nécessite une modification orthographique particulière à certaines personnes.
Answer: mangions — le radical « mang- » issu de « nous mangeons » conserve un « g » simple devant la terminaison « -ions » car le « i » qui suit rend le « g » naturellement doux, rendant le « e » intercalaire inutile à cette personne
When forming the imparfait in French, your starting point is always the nous form of the present tense — drop the -ons ending to get your radical, then add the imparfait endings (-ais, -ais, -ait, -ions, -iez, -aient). For manger, that present-tense nous form is mangeons, giving you the radical mange-. The -e- exists in mangeons because without it, the g before o would harden to a /g/ sound, distorting pronunciation. However, at the nous and vous persons of the imparfait, the endings begin with -i- (-ions, -iez), and a g followed by i is naturally soft — no intercalary e is needed. So the correct form is mangions, making choice A right.
Choice B (mangeons) is wrong because it simply transplants the present-tense nous form wholesale into the imparfait without applying the proper ending. The -eons ending belongs only in the present indicative.
Choice C (manjions) introduces a j, which never replaces g in French -ger verbs. The soft sound is preserved through the e intercalaire or naturally by a following front vowel like i — never by substituting j.
Choice D (mangiions) doubles the i, which is a pure invention. There is no grammatical rule in French that adds an extra i for nasality or any other reason at this person.
Study tip: For all -ger verbs at the imparfait, remember the e intercalaire only appears before -a- and -o- endings (e.g., je mangeais, il mangeait) — not before -i-, where the g stays soft on its own.
- Lequel des choix suivants complète correctement la phrase avec la forme appropriée de l'imparfait ?
Answer: tenais — formé à partir du radical « ten- » avec la terminaison de la première personne du singulier de l'imparfait
When conjugating any verb to the imparfait in French, there's a reliable two-step formula: take the nous form of the present tense, drop the -ons ending, and add the imparfait endings (-ais, -ais, -ait, -ions, -iez, -aient). This rule applies to virtually every French verb, including irregular ones like tenir.
For tenir, the present-tense nous form is nous tenons. Drop -ons and you get the stem ten-. Add the first-person singular ending -ais, and you arrive at tenais — making A the correct answer. The sentence reads: "Quand j'étais petit, je tenais toujours la main de ma mère." This is grammatically and stylistically perfect for describing a repeated past habit, which is exactly what the imparfait is used for.
Choice B (tienais) is a tempting trap because je tiens is indeed the first-person singular present tense of tenir — but you must use the nous form as your stem source, not the je form. Using tien- here is a classic beginner error. Choice C (tenois) uses the correct stem but applies an archaic Old French ending that no longer exists in modern French; if you ever encounter -ois endings, know they belong to a historical form of the language, not contemporary conjugation. Choice D (tinais) pulls the stem tin- from the passé simple (je tins), which is an entirely different tense — mixing tense stems is a serious structural error.
Your go-to study tip: **always derive your imparfait stem from nous in the present tense.** Write it out explicitly for irregular verbs like tenir, venir, and faire until it becomes automatic.
