The middle and end of an action are marked in French by two families of lexical aspectual verbs: the continuative family (continuer, persister, s'obstiner, rester, demeurer) and the terminative family (finir, arrêter, cesser, achever, terminer). Within each family the verbs are not synonyms — they carry distinct connotations of register, attitude, and the kind of ending or continuation involved. The pair that learners get wrong most often is finir de vs finir par: same verb, different prepositions, opposite meanings. Mastering this pair is one of the clearest signs of moving from intermediate to fluent French.
This page drills the continuative and terminative systems together, with special attention to the finir de / finir par contrast, the continuer à / continuer de stylistic split, and the formal-vs-everyday register choices among the terminative verbs.
Continuative: keeping an action going
continuer à / de + infinitive — the everyday "keep doing"
Continuer can be followed by either à or de before an infinitive. Both are accepted by the Académie française and by all major dictionaries; neither is wrong. The choice is stylistic, not semantic.
- continuer à — slightly more common in spoken French; the everyday default.
- continuer de — slightly more literary, careful, or written. Often preferred when continuer à would create awkward vowel adjacency.
Elle continue à étudier le français malgré son emploi du temps chargé.
She keeps studying French despite her busy schedule.
Il continue de pleuvoir depuis ce matin.
It keeps raining — it's been raining since morning. (slightly literary)
Tu continues à travailler le week-end ?
Are you still working on weekends?
On continue de penser à toi tous les jours.
We keep thinking about you every day.
Si tu continues à parler, je m'en vais.
If you keep talking, I'm leaving.
The euphony rule: when the next infinitive starts with a vowel, continuer d' is preferred to avoid the ugly à a- cluster.
Le train continue d'arriver en retard.
The train keeps arriving late. (continuer à arriver would be awkward — à + a-)
Il continue d'écrire des poèmes.
He continues writing poems.
In practice, continuer à covers most spoken French, continuer d' + vowel-initial infinitive is the smooth default, and continuer de + consonant-initial infinitive belongs to careful or literary registers.
Continuer with a noun phrase
Continuer can also take a direct object — continuer ses études, continuer la conversation, continuer la route. No preposition needed.
Il a décidé de continuer ses études en Allemagne.
He decided to continue his studies in Germany.
On continue la conversation après le dîner ?
Shall we continue the conversation after dinner?
persister à + infinitive — keep doing despite
Persister à = "persist in / keep doing despite obstacles." The verb adds a layer of stubbornness or determination — the subject is going against advice, evidence, or common sense.
Il persiste à dire qu'il n'était pas là, malgré les témoins.
He persists in claiming he wasn't there, despite the witnesses.
Pourquoi tu persistes à l'appeler après tout ce qu'il t'a fait ?
Why do you keep calling him after everything he's done to you?
Le médecin persiste à recommander le repos.
The doctor maintains his recommendation of rest.
The preposition is fixed: à.
s'obstiner à + infinitive — be obstinate about
Stronger and more pejorative than persister. S'obstiner à = "be obstinate / dig one's heels in." Almost always carries criticism.
Elle s'obstine à porter ce pull en pleine canicule.
She insists on wearing that sweater in the middle of the heat wave.
Ne t'obstine pas, on s'est tous trompés un jour.
Don't dig in — we've all been wrong at some point.
Il s'est obstiné à refuser toute aide.
He stubbornly refused all help.
The preposition is à.
rester / demeurer + adjective — remain (in a state)
A different syntactic shape: rester + adjective (or past participle, or noun phrase) = "stay / remain (in a state)." This is the everyday continuative for states rather than activities.
Reste calme, ce n'est pas grave.
Stay calm — it's not a big deal.
Elle est restée silencieuse pendant toute la réunion.
She remained silent throughout the meeting.
Le magasin est resté ouvert pendant la grève.
The store stayed open during the strike.
The slightly more formal demeurer is reserved for literary or elevated registers:
Il est essentiel de demeurer fidèle à ses principes.
It's essential to remain faithful to one's principles. (formal)
Le mystère demeure entier.
The mystery remains complete. (literary)
In conversation, rester is the everyday choice; demeurer would sound stilted.
Continuer + adjective — uncommon, with one set use
Unlike rester, continuer + adjective is generally not used. The main exception is the set construction continuer fort (informal) used as a metaphor for "keep going strong":
Son nouvel album continue fort dans les charts.
His new album keeps going strong in the charts. (informal)
For state continuation, default to rester.
Terminative: ending an action
The terminative zone is the most heavily populated of the four aspectual zones — five verbs are in everyday use, with sharp meaning differences.
finir de + infinitive — finish doing (natural completion)
Finir de = "finish doing." The action runs to its natural completion. The subject was doing X, X reaches its endpoint, and now X is done.
J'ai fini de lire ton article — c'est très bien écrit.
I've finished reading your article — it's really well written.
Quand tu auras fini de manger, on partira.
When you've finished eating, we'll leave.
Elle finit de préparer le dîner et on passe à table.
She's finishing dinner and then we sit down.
Je n'ai pas encore fini de ranger.
I haven't finished tidying up yet.
The preposition is fixed: de. Never finir à in this meaning.
finir par + infinitive — end up doing (eventual outcome)
Finir par does not mean "finish doing." It means "end up doing / eventually do" — the action that finally happens after a process, hesitation, or delay. This is the high-stakes contrast in the French aspectual system, and it consistently trips learners up.
Après deux heures de discussion, ils ont fini par accepter.
After two hours of discussion, they ended up accepting.
Tu finiras par comprendre, ne t'inquiète pas.
You'll eventually understand, don't worry.
J'ai fini par lui dire la vérité.
I ended up telling him the truth.
Si tu insistes, il finira par céder.
If you insist, he'll eventually give in.
Elle a fini par s'endormir vers minuit.
She finally fell asleep around midnight.
Compare directly:
- J'ai fini de manger. — I finished eating. (the eating is complete)
- J'ai fini par manger. — I ended up eating. (after some hesitation, I finally ate)
The semantic gap is wide. Finir de names the completion of an action that was already in progress. Finir par names the eventual occurrence of an action that was uncertain, delayed, or hesitant.
arrêter de + infinitive — stop doing (interruption)
Arrêter de = "stop doing / quit." The action is interrupted, often deliberately, often as a permanent decision. This is the everyday "stop" verb in French and is heavily imperative-friendly.
Arrête de me regarder comme ça !
Stop looking at me like that!
J'ai arrêté de fumer il y a deux ans.
I quit smoking two years ago.
Tu peux arrêter de te plaindre, s'il te plaît ?
Can you stop complaining, please?
Le bébé n'arrête pas de pleurer depuis ce matin.
The baby hasn't stopped crying since this morning.
The negative ne pas arrêter de effectively converts arrêter into a continuative-iterative: "not stop = keep on."
The preposition is fixed: de.
cesser de + infinitive — cease (formal)
Cesser de = "cease to / stop." Slightly formal, more literary than arrêter. In casual speech it sounds stiff; in writing, journalism, or careful prose it is the natural choice.
Il n'a pas cessé de pleuvoir de la journée.
It didn't stop raining all day.
Elle ne cesse de répéter la même histoire.
She doesn't stop repeating the same story.
Cessez de me déranger pendant que je travaille !
Stop interrupting me while I'm working! (formal/elevated tone)
A famous quirk: the literary form ne... cesser de — without pas — is one of the rare modern French constructions where ne still survives without its partner pas. Il ne cesse de parler means the same thing as il ne cesse pas de parler: "he doesn't stop talking." Both are grammatical; the ne... cesser de form (no pas) sounds elevated and is common in journalism and literary prose.
Le climat ne cesse de se réchauffer.
The climate keeps warming up. (literary, journalistic register)
Cet auteur ne cesse de me surprendre.
This author keeps surprising me. (elevated)
This is one of the few places where modern standard French still allows ne without pas. (The others — je n'ose, je ne saurais, je ne peux — are also fossilized.)
achever de + infinitive — complete the final part of
Achever de = "finish (the last part of) / complete." The verb emphasizes the completion of a process that was already underway. Slightly formal.
Il achève de rédiger son rapport avant la réunion.
He's finishing his report before the meeting.
Cette nouvelle a achevé de la convaincre.
That news finished convincing her. (idiomatic — sealed her conviction)
J'ai achevé de lire le manuscrit hier soir.
I finished reading the manuscript last night.
In everyday French, finir de is more common; achever de belongs to careful prose and writing. The two often overlap in meaning, but achever carries a slightly more deliberate "completion" connotation.
terminer + direct object — finish (a thing)
Terminer is transitive — it takes a direct object (a noun phrase), not an infinitive. This is its key syntactic difference from finir.
J'ai terminé mon rapport hier soir.
I finished my report last night.
Termine ton assiette avant le dessert !
Finish your plate before dessert!
On va terminer la bouteille avant de partir.
We'll finish the bottle before we leave.
To say "finish doing" with terminer, you would need a noun like la lecture, la rédaction: terminer la lecture du livre. In practice, French speakers shift to finir de + infinitive for this purpose. Terminer de + infinitive is grammatically possible but feels heavier than finir de; finir de manger is the everyday choice over terminer de manger.
The full ending paradigm — choosing the right verb
Compare these five sentences, all loosely meaning "to end an action":
J'ai fini de manger.
I've finished eating. (natural completion — the meal is done)
J'ai fini par manger.
I ended up eating. (after hesitation — opposite shading)
J'ai arrêté de manger.
I stopped eating. (deliberate interruption — perhaps for health)
Je n'ai pas cessé de manger.
I didn't stop eating. (continuous — formal/literary)
J'ai achevé de manger.
I finished eating. (slightly formal — the eating is complete)
J'ai terminé mon repas.
I finished my meal. (with direct object — the meal is the object)
Each one is grammatical, and each one says something different. The contrast between fini de and fini par is the most consequential, but the register split between arrêter and cesser is nearly as important.
Key syntactic rules across the family
Negation
Negation wraps the conjugated verb, not the infinitive.
Il n'a pas fini de manger.
He hasn't finished eating.
Je n'arrête pas de penser à toi.
I can't stop thinking about you.
Elle ne continue plus à fumer.
She no longer keeps smoking.
Object pronouns
Object pronouns sit before the infinitive, not before the conjugated verb:
Tu as fini de le lire ?
Have you finished reading it?
J'ai fini par l'accepter.
I ended up accepting it.
Elle continue à m'écrire tous les mois.
She keeps writing to me every month.
Arrête de leur en parler !
Stop talking to them about it!
Tense — the conjugated verb takes the tense
All these verbs can move into any tense by conjugating the lexical verb, with the infinitive untouched.
Quand je suis arrivé, il finissait de parler.
When I arrived, he was finishing speaking. (imparfait)
Tu auras fini de manger avant 8 heures ?
Will you have finished eating by 8? (futur antérieur)
Si tu arrêtais de râler, on pourrait parler.
If you stopped grumbling, we could talk. (imparfait in si-clause)
The set phrase: en finir avec / en finir de
A high-frequency idiom: en finir avec + noun = "be done with / finish with"; en finir de + infinitive = "be done with doing." The en is fossilized — it doesn't refer to anything specific, but it's mandatory.
Je veux en finir avec cette histoire.
I want to be done with this whole business.
Quand est-ce qu'on va en finir d'attendre ?
When will we be done waiting?
Pour en finir avec la question, oui, j'accepte.
To put an end to the question, yes, I accept.
This is distinct from finir avec (without en), which is rare. The fixed en finir is the idiom learners need to recognize.
Common Mistakes
Mistake 1: Confusing finir de and finir par.
❌ Après une heure de débat, ils ont fini de accepter.
Wrong meaning entirely. Finir de = complete the action. For 'eventually do, end up doing' = finir par.
✅ Après une heure de débat, ils ont fini par accepter.
After an hour of debate, they ended up accepting.
Mistake 2: Using cesser in casual speech.
❌ Cesse de m'embêter, je travaille !
Grammatically fine but stiff. The everyday verb is arrêter.
✅ Arrête de m'embêter, je travaille !
Stop bothering me — I'm working!
Mistake 3: Putting the wrong preposition with finir or arrêter.
❌ J'ai fini à manger. / Arrête à parler !
Both verbs take de, never à.
✅ J'ai fini de manger. / Arrête de parler !
I've finished eating. / Stop talking!
Mistake 4: Treating terminer like a periphrastic verb with infinitive.
❌ Termine de manger, on part !
Possible but unidiomatic. The everyday verb with infinitive is finir de.
✅ Finis de manger, on part !
Finish eating — we're leaving!
Mistake 5: Misreading the ne... cesser de construction without pas.
❌ Il ne cesse de pleuvoir = It stops raining.
The literary ne... cesser de (without pas) means 'doesn't stop' / 'keeps on.' This is one of the few cases where ne survives alone in modern French.
✅ Il ne cesse de pleuvoir = It keeps raining (formal).
The construction is continuative, not terminative.
Mistake 6: Using continuer à + vowel-initial infinitive.
❌ Le train continue à arriver en retard.
The à + a- adjacency is awkward. Use continuer d' before vowel-initial infinitives.
✅ Le train continue d'arriver en retard.
The train keeps arriving late.
Mistake 7: Forgetting that finir par changes the meaning radically.
❌ Je vais finir de te dire la vérité un jour (when meaning 'eventually I'll tell you').
Finir de = complete an ongoing action. For 'I'll eventually do X' = finir par.
✅ Je vais finir par te dire la vérité un jour.
I'll end up telling you the truth one day.
Key takeaways
The continuative system in French is led by continuer à / de + infinitive (interchangeable, with à slightly more spoken and de slightly more literary), supported by persister à (stubborn continuation), s'obstiner à (stubborn-pejorative), and the state-continuative rester + adjective (everyday) / demeurer + adjective (literary).
The terminative system has five verbs with sharp meaning differences. Finir de + infinitive is "finish doing" (natural completion). Finir par + infinitive is "end up doing / eventually do" (delayed outcome). These two carry opposite shadings and are the most important pair in the system. Arrêter de is the everyday "stop." Cesser de is the formal "cease," with the special literary form ne... cesser de (no pas) meaning "keep on / not stop." Achever de is the formal "finish completing." Terminer is transitive — takes a direct object, not an infinitive.
Across the whole family, the prepositions are fixed (continuer à/de, persister à, s'obstiner à, finir de, finir par, arrêter de, cesser de, achever de), negation wraps the conjugated verb, object pronouns sit before the infinitive, and tense lives entirely in the lexical aspectual verb. Memorize the finir de / finir par contrast first — it carries the most semantic weight in the system.

- Lexical Aspectual Verbs: Beginning, Continuing, Ending, RepeatingB1 — French uses lexical aspectual verbs — commencer, se mettre à, continuer, finir, arrêter, cesser, achever — to mark the phases of an event. This page maps the system, distinguishes near-synonyms, and shows when each verb is right.
- Inceptive Aspect: commencer à, se mettre à, and MoreB1 — How French marks the start of an action: the neutral commencer à, the sudden se mettre à, the formal débuter and entamer, and the colloquial partir + infinitive. Each verb covers a different shading of beginning.
- Aspectual Periphrases: How French Marks Aspect Without InflectionB1 — French has no inflectional progressive or perfect aspect like English -ing or have done. Instead it builds aspect with periphrases — verb + preposition + infinitive — to mark beginnings, continuations, endings, habits, imminence, and recency.
- De vs À with Verbs Before an InfinitiveA2 — When one French verb is followed by another in the infinitive, the link between them is either nothing, the preposition de, or the preposition à. The choice is largely arbitrary and must be memorised verb by verb — but there are patterns and tendencies that make the lists learnable.
- L'Impératif Négatif: Position des PronomsA2 — In the negative imperative, object pronouns revert to their normal pre-verbal position — and moi/toi shift back to me/te. The whole apparatus of the affirmative is undone, which makes the affirmative-vs-negative pair the most-drilled asymmetry in French syntax.
- Aspectual Verbs + Infinitive: commencer, finir, continuer, arrêterA2 — French aspectual verbs — commencer, finir, continuer, arrêter, cesser, se mettre — take an infinitive complement through a preposition (à, de, par). The choice of preposition changes the meaning, and the contrasts commencer à/par and finir de/par are central to natural French.
