Concept Map — Imparfait vs Passé Composé

The pair that decides whether French past speech sounds native. Both are
"past tense" in English, so the choice is invisible to a translator — you pick
by function, not by the English verb.

Anchor

French splits the past into two jobs. Passé composé moves the story forward:
single, completed events ("and then this happened"). Imparfait holds the
scene still: background, description, habits, and feelings that were simply
going on. Most past narration alternates between them in the same paragraph —
PC for the beads, imparfait for the string.

Prerequisites

Control these before drilling the contrast:

• [[Passe-Compose-Formation]] (create) — avoir/être + past participle; which verbs take être.
• [[Etre-Verbs-Agreement]] (create) — gender/number agreement on être verbs. Already a logged weak point: je suis allée, je suis restée, je me suis levée (see Control Center → Current Weak Points).
• [[Imparfait-Formation]] (create) — nous present stem − -ons + endings -ais/-ais/-ait/-ions/-iez/-aient. Only irregular stem: être → ét-.

The Contrast

Pick by the function in the story, not the English word.

Cue / Function	Passé Composé (event)	Imparfait (frame)
A single completed action	J'ai mangé à 8h.	—
A sequence "and then… and then…"	Je suis entrée, j'ai vu Paul, on a parlé.	—
Something that interrupts	Je dormais quand le téléphone a sonné.	Je dormais quand…
Background / setting the scene	—	Il faisait nuit, il pleuvait.
Ongoing action ("was -ing")	—	Je regardais un film.
Habit / repeated past ("used to / would")	—	Quand j'étais petite, je jouais dehors.
Description, feelings, age, weather, time	—	Elle était fatiguée. J'avais 20 ans.
A state with a clear start/end or duration	J'ai vécu 3 ans à Sydney. (closed)	J'habitais à Sydney. (just context)

Same verb, different meaning by tense — high-value pairs:

Verb	Passé composé	Imparfait
savoir	J'ai su = I found out	Je savais = I knew
pouvoir	J'ai pu = I managed to	Je pouvais = I was able / could
vouloir	J'ai voulu = I decided to / tried	Je voulais = I wanted
connaître	J'ai connu = I met (first time)	Je connaissais = I knew (was familiar)
devoir	J'ai dû = I had to (and did)	Je devais = I was supposed to

Companion Language Points

Learn these in the same sessions — they're what make the choice automatic:

• [[Past-Time-Markers]] (create) — the words that flag each tense:
  • → Passé composé: soudain, tout à coup, un jour, hier, ce matin-là, puis, ensuite, enfin.
  • → Imparfait: tous les jours, souvent, toujours, d'habitude, pendant que, à l'époque, quand j'étais….
• [[Plus-Que-Parfait]] (create) — "had done"; the step before a passé composé event (J'avais déjà mangé quand il est arrivé.). The natural next dot.
• être en train de + infinitif — emphasises the ongoing action the imparfait already implies (flagged "ahead-of-curriculum" in [[french-learning-crossref]]).

Fixed Expressions

Memorize whole — they hard-wire the right tense:

French	Use
Il était une fois…	"Once upon a time" — storytelling opener (always imparfait).
Quand j'étais petit·e, …	"When I was little…" — habit frame.
C'était + adjectif (c'était génial / nul / incroyable)	reacting to a past experience.
Il y avait…	"there was/were" (scene-setting) vs il y a eu = "there occurred".
Comme d'habitude, …	"as usual" — triggers imparfait.
Tout à coup, …	"all of a sudden" — triggers passé composé.

What Completes It / Study Next

• [[Plus-Que-Parfait]] (create) — completes the past system: background (imparfait) ▸ earlier event (plus-que-parfait) ▸ main event (passé composé).
• [[Conditionnel-Passe]] (create) — si + plus-que-parfait → conditionnel passé (regret/hypothetical); already met passively in the Iran vlog ([[french-learning-crossref]]).
• Drill direction: once the contrast feels automatic, tell a whole past story (a trip, a bad day) and watch the alternation.

Production Drill

Scene: Tell the story of a memorable meal or a trip — out loud, 6–8 sentences.

Force yourself to use, in one telling:

• at least 3 passé composé events (what happened, in order);
• at least 3 imparfait frames (weather, mood, setting, what was going on);
• one quand … + interruption sentence (imparfait + PC together);
• one correct être-verb agreement (je suis allée / arrivée / restée).

Then check against the contrast table and log any broken sentence as a weak point.
