What this is
No new grammar shows up in this lesson. Every rule below was already taught somewhere in M4–M8 — adjective agreement and position, the meaning-shift set, the full possessive paradigm, the negation family, all three question registers, and now all three regular present-tense verb families (-er, the two -ir patterns, and -re). What changes is the shape of the practice: instead of thirty examples that each drill one rule on its own, every sentence here pulls together at least two of those rules at once, because that’s what an actual sentence does.
Block A’s review proved the mechanism works for nouns and verbs. Block B is a harder test, because its five concept groups interact with each other constantly in real speech — you rarely say a possessive without also negating something nearby, or ask a question without describing the thing you’re asking about, or conjugate a verb without doing all three at once. This module is where that interaction gets forced into the open, now with three more verb shapes in the mix.
The rule — a recombination map, not new rules
Nothing here is graded by concept, and the angle labels name pairings rather than single topics: adjective-plus-possessive-combination, verb-family-plus-negation-combination, three-concept-combination. A sentence like “Ton vieux patron n’est-il jamais content ?” is doing four jobs at once — a possessive (ton), a position-sensitive adjective (vieux sitting before the noun), a negation (jamais), and formal inversion — with none of them flagged as the point of the sentence. Add a verb family into the mix, as in “Ses clients ne répondent plus à ses lettres,” and a fifth thread joins: répondre keeping its own preposition (à) even while wrapped in negation.
A few threads worth tracing across the set:
| Thread | Where it shows up |
|---|---|
| Agreement machinery | Adjectives, and possessives, agree with the noun — never with the speaker or the owner |
| son/sa/ses vs leur/leurs | Reused with owners of both genders, so the pattern can’t be pattern-matched from context |
| Article collapse under negation | un/du/des → de after ne…pas, but never after être and never under ne…que |
| Position carries meaning | ancien, pauvre, seul, and similar words are reused so their sense has to be read from where they sit, not guessed |
| Three question registers | Intonation, est-ce que, and inversion all reused to ask about possessed or described things |
| Elision and euphony | mon/ton/son before a vowel-initial feminine noun; the -t- (or its absence) in inversion |
| Telling the -ir families apart | The plural is the tell: finissent inserts -iss-, dort/sort/part never would, at any number |
| Zero-ending verbs | vend, perd, attend, répond — the entire -re family’s 3rd-person singular is the bare stem, nothing added |
Why it works this way
A rule practiced in isolation is a rule you recognize when reminded, not one you can produce on demand. The vocabulary and grammar from M4–M8 were each demonstrated cleanly, one concept at a time — which is exactly the condition under which a learner can still guess the right answer from knowing which lesson they’re on. That crutch disappears here: nothing about this page tells you whether the next blank needs a possessive, a negation, a question word, or which of the four verb families the sentence’s verb belongs to. You have to recognize which rule applies from the sentence itself, which is the actual skill.
It’s also a genuine stress test of the vocabulary ledger’s gating. Every word in this set was already taught by the end of M8; if a sentence here reads awkwardly, that’s a signal the word wasn’t taught with enough surrounding context to be reusable on its own.
Edge cases
Zero new vocabulary, zero new grammar
Every word in this set comes from the M1–M8 ledger, which is why vocab.json for this concept is empty. If a sentence needed a word outside that set, the fix was to rewrite the sentence, not add the word.
A sentence must combine, not just restate
Swapping the noun in an already-seen frame doesn’t count. Every sentence here crosses at least two Block B concepts — an adjective’s position paired with a negation, a possessive paired with a verb-family conjugation, or (in the three-concept-combination set) three or more at once, like “Sa nouvelle maison n’est-elle pas très belle ?”, which stacks a possessive, an adjective before the noun, an adjective after it, a negation, and an inverted question in a single sentence.
Telling the two -ir families apart only shows up in the plural
“Mes sœurs finissent leur repas, mais mon frère dort encore” puts the two -ir families side by side on purpose: finissent inserts -iss- because it’s from the finir family; dort never would, at any number, because dormir belongs to the other one. In the singular, both families can look deceptively similar (je finis / je dors both end in -s), so the plural is the only reliable test — and it’s exactly the form English speakers tend to skip when guessing a new verb’s family.
The concepts most likely to be forgotten get priority
Four points are deliberately overrepresented relative to how often they’d naturally occur: son/sa/ses agreeing with the thing owned rather than the owner (a genuine trap for English speakers, who expect the possessive to track the owner), the article collapse under ne...pas versus its absence under ne...que, the fact that interrogative que can never be the last word of a sentence, and telling the two -ir verb families apart by their plural form. These are the rules most likely to quietly regress without deliberate reinforcement.
What English speakers get wrong here
The mistakes in recombination are different from the mistakes in a single-topic lesson. In isolation, most learners get son livre right in a possessives lesson, pas de vin right in a negation lesson, and il finit right in an -ir verbs lesson. Combined, the common failure is carrying a rule across a clause boundary where it doesn’t apply — collapsing an article to de after être or after que just because a negation appeared somewhere earlier in the sentence, or assuming a new -ir verb takes -iss- in the plural just because the last one did. Each verb phrase and each clause has to be checked on its own terms.
The second common mistake is choosing son or sa by the gender of the person being discussed rather than the noun that follows — reaching for sa because the owner is female, even when the noun owned is masculine. The fix is the one from M5: the possessive is deaf to the owner and only ever listens to the noun.
The third is dropping the euphonic -t-, or inserting one where it isn’t needed, in inversion. It appears only between two vowel sounds (parle-t-il), never after a verb that already ends in a pronounced consonant (est-il, part-il, dort-il, travaillez-vous).
The fourth is forgetting that a -re verb’s 3rd-person singular has no ending whatsoever — il vend, never il vends or il vende — the one present-tense form in the whole language that is just the bare stem.
