Aspectual Periphrases: How French Marks Aspect Without Inflection

English speakers come to French armed with a powerful aspectual system: I eat / I am eating / I have eaten / I had been eating / I am about to eat / I just ate / I keep eating. Each of these is a different shape of the verb — different auxiliaries, different participles, different tenses — and each marks a specific contour of the action in time. French has none of this inflectional machinery. There is no -ing form acting as a present progressive, no fine-grained perfect-vs-preterite split, no dedicated future-in-near-time. Yet French speakers express every one of these nuances. The trick is that French outsources aspect to periphrastic constructions — fixed phrases of the shape verb + (preposition) + infinitive — and the periphrasis carries the aspectual meaning that English encodes morphologically.

This page is the map of that system. Each periphrasis covered here has a dedicated page where you can drill the conjugation and the edge cases; this page connects them. Once you can scan an event and pick the right periphrasis — je vais le faire (going to), je viens de le faire (just did), je suis en train de le faire (in the middle of doing), je suis sur le point de le faire (about to), je commence à le faire (starting to), j'ai fini de le faire (finished doing) — you have unlocked the part of French that learners with only textbook tense charts find frustratingly out of reach.

Why French needs periphrases

Latin had a rich aspectual morphology, and French inherited the bones of it: the imparfait still marks imperfective past, the passé composé and passé simple mark perfective past, the futur and conditionnel exist as inflected categories. But the more delicate aspectual nuances — just, about to, in the middle of, in the habit of, starting to, keeping on — were never inflected, and modern French has not invented an inflectional progressive the way Romance cousins like Spanish (estar comiendo) or Italian (sto mangiando) have institutionalized one. Instead, French built a parallel system out of light verbs that grammaticalized into aspectual operators.

Each periphrasis follows a small, predictable template:

[light verb conjugated for tense and person] + (preposition) + [infinitive of the lexical verb]

The light verb carries person, tense, and aspect. The infinitive names the action. The preposition is required (or absent) by the construction, not by the lexical verb — commencer à faire takes à even though faire doesn't. Memorize each periphrasis as a unit; do not try to derive the preposition from semantics.

The aspectual landscape

Aspect is not tense. Tense locates an event on the timeline (past, present, future); aspect describes its internal shape — whether it is starting, continuing, ending, habitual, complete, or anticipated. French periphrases populate six aspectual zones.

Notice that the same lexical verb — say, manger — can be threaded through the entire system:

This sequence is the spine of French aspect. Each periphrasis names a distinct phase of the event, and a fluent speaker reaches for them as automatically as an English speaker reaches for am eating, just ate, was about to eat.

Imminent: aller + inf, être sur le point de + inf

For events on the near horizon, French has two periphrases that overlap in meaning but differ in immediacy and register.

aller + infinitive — the futur proche — is the everyday way to say something is going to happen. Distance can be a few seconds (il va tomber !, "he's going to fall!") or several years (je vais déménager l'année prochaine, "I'm going to move next year"). The preposition slot is empty — bare aller + infinitive.

être sur le point de + infinitive is the high-resolution version: the event is so close it could begin in the next sentence. If aller covers "going to," être sur le point de covers "about to" / "on the verge of."

For the full treatment see futur proche and être sur le point de.

In progress: être en train de + inf

This is the closest French gets to a present progressive — and it is conspicuously not the default. While English uses the -ing progressive almost obsessively (I am eating, she is sleeping, we are arriving), French uses the simple present where English would use the progressive (je mange, elle dort, on arrive). The progressive periphrasis être en train de + infinitive is reserved for emphasizing that the action is right now, in progress, not yet finished.

A non-emphatic English progressive (I'm reading a good book lately) does not translate with en train de — use the simple present (je lis un bon livre en ce moment). Reserve être en train de for when you genuinely want to flag that the action is in mid-flow.

Recent past: venir de + inf

The recent past — I just did X — has a dedicated periphrasis: venir de + infinitive. The auxiliary is venir in the present (or imparfait, for "had just"), and the de is mandatory.

There is no separate French construction for had just — the imparfait of venir does the entire job. See passé récent: venir de for full coverage.

Inceptive: commencer à + inf, se mettre à + inf

Two periphrases mark the start of an action, and they are not interchangeable.

commencer à + infinitive is the neutral "start to / begin to." It works with any subject and any verb, and treats the start as the beginning of a process that is expected to continue.

se mettre à + infinitive is the sudden, often unexpected start. It frames the onset as a moment of switching states — the subject was not doing X, and abruptly began. It pairs especially well with verbs of crying, laughing, running, shouting, raining hard.

The reflexive se mettre governs à; this is fixed.

Continuative: continuer à / de + inf

To say that an action keeps going, French uses continuer + à or de + infinitive. Both prepositions are accepted by the Académie française and by major dictionaries; in practice continuer à is more common in spoken French and continuer de is slightly more literary.

There is no semantic difference; the choice is stylistic. Avoid stacking two vowel sounds: continuer à arriver (à + a-) is awkward, so continuer d'arriver is preferred for euphony.

Terminative: finir de, arrêter de, cesser de + inf

Three periphrases mark the end of an action, and they are not synonyms.

finir de + infinitive — finish doing something. The action runs to its natural completion.

arrêter de + infinitive — stop doing something. The action is interrupted, often deliberately. Strongly imperative-friendly: arrête de ! is a frequent command.

cesser de + infinitive — cease to do something. Slightly formal/literary; common in negative form (ne) cesser de meaning "to keep on / not stop."

The ne...cesser de construction without pas is a literary idiom that means the opposite of cease — it means "constantly do," because the unbroken negation of cease equals continuous action. This is one of the few places where modern French still permits ne without a partner pas.

Habitual: avoir l'habitude de + inf

For habitual or customary action — I'm used to doing X — French uses avoir l'habitude de + infinitive. This is not the same as the imparfait, which marks past habit; avoir l'habitude explicitly names a habit as the speaker's normal pattern.

There is no inflected counterpart for habitual aspect in French — the periphrasis is the only way.

Result: finir par + inf

A subtle but high-frequency periphrasis: finir par + infinitive does not mean "finish doing." It means "end up doing" — the action that finally happens after a process or delay. Compare:

• 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)

This is one of the periphrases learners discover late and then use everywhere — it captures a meaning English needs five words to express.

Causative: faire + inf

A short note for completeness: French has a productive causative periphrasis faire + infinitive that means "have/make someone do something" or "have something done." It works across all tenses and is heavily used.

This deserves its own page; see verbes/causative/faire-causatif for the full pronoun and word-order rules, which are nontrivial.

Cross-cutting feature: how negation, pronouns, and tense work

All aspectual periphrases share the same syntactic behavior:

1. Negation wraps the conjugated verb, not the infinitive. Je ne vais pas manger (I'm not going to eat), je n'ai pas l'habitude de fumer (I'm not used to smoking), il n'a pas fini de parler (he hasn't finished talking).

2. Object pronouns sit before the infinitive, not before the conjugated verb. Je vais le faire (I'm going to do it), je viens de la voir (I just saw her), je suis en train de les écrire (I'm in the middle of writing them).

3. The conjugated verb takes the tense. Every periphrasis can be moved into any tense by conjugating the light verb. This means aller in the imparfait gives "was going to" (j'allais manger), venir in the imparfait gives "had just" (je venais de manger), commencer in the passé composé gives "started to" (j'ai commencé à manger).

These three rules are uniform across the entire system — once you've learned them for one periphrasis, you've learned them for all.

Common Mistakes

Mistake 1: Inserting à or de where the construction takes none.

Mistake 2: Picking the wrong preposition for commencer and finir.

Mistake 3: Translating I just did X with the passé composé alone.

Mistake 4: Using être en train de for every English progressive.

Mistake 5: Confusing finir de and finir par.

Mistake 6: Putting object pronouns before the conjugated light verb.

Key takeaways

French has no inflectional progressive or recent-past, but it covers the same aspectual ground with periphrases: light verb + (preposition) + infinitive. The key set is aller (going to), être sur le point de (about to), être en train de (in the middle of), venir de (just did), commencer à / se mettre à (starting to), continuer à/de (keep), finir de / arrêter de / cesser de (stop), avoir l'habitude de (be used to), and finir par (end up). Each periphrasis is a fixed unit — memorize the preposition, do not derive it.

Across all of them, three syntactic rules are uniform: negation wraps the light verb, object pronouns sit before the infinitive, and tense lives entirely in the light verb. Drill the system as a set rather than one piece at a time, because fluency in spoken French depends on reaching for the right periphrasis as quickly as an English speaker reaches for am doing, just did, about to do. The rest of this section unpacks each periphrasis on its own page; this overview is the index.
