Être en train de + infinitive: emphasising an action in progress

Ne me dérange pas, je suis en train de travailler.Don't disturb me, I'm working right now.

French has no separate "-ing" verb form the way English does — the plain present tense already covers an ongoing action (je travaille can mean both "I work" and "I'm working"). When you want to underline that something is happening right now, as we speak, French reaches for être en train de + infinitive instead.

Quick shortcut: conjugate être, add en train de, then the infinitive: je suis en train de manger, elle est en train de lire. The present-tense form only ever describes right now, never a future plan or a habit — but être itself can be conjugated in other tenses to place the "in progress" moment elsewhere in time.

The form

être (conjugated for the subject) + en train de + infinitive:

en train de itself never changes — only être is conjugated, and the second verb stays in the infinitive:

• Je suis en train de cuisiner.
• Ils sont en train de discuter.
• Nous sommes en train de déménager.

If you haven't met être yet, it's covered in The verb être.

Why French bothers, when the present already works

This is the real question the construction answers. Plain present tense (see Present tense: -er verbs) is genuinely ambiguous between a habitual/general fact and something happening at this moment:

• Je mange. — could mean "I eat [in general]" or "I'm eating [right now]."
• Je suis en train de manger. — marks the action as in progress and rules out the habitual reading.

That "in progress" moment doesn't have to be the literal instant of speaking, either — Il est en train d'écrire un roman ("He's in the middle of writing a novel") describes something ongoing over a whole period, not one instant.

So être en train de isn't a grammatical requirement — it's a tool for emphasis and clarity. Reach for it when the context alone won't make "right now" obvious, or when you want to stress that an action is genuinely in progress and shouldn't be interrupted:

• Chut, les enfants sont en train de dormir. (Shh, the kids are sleeping right now.)
• Qu'est-ce que tu es en train de faire ? (What are you doing right now?)
• Attends, je suis en train de finir un truc. (Wait, I'm in the middle of finishing something.)

When the moment-in-time is already clear from context or from a time word, plain present is perfectly natural and more common — you don't need être en train de on every ongoing action.

Talking about an ongoing action in the past

Put être in the imparfait instead of the present, and the same construction describes something that was in progress at a past moment — often right when something else happened:

• J'étais en train de dormir quand le téléphone a sonné. (I was sleeping when the phone rang.)
• Elle était en train de lire quand nous sommes arrivés. (She was reading when we arrived.)

This mirrors how imparfait alone can already express an ongoing past action — être en train de just makes the "right in the middle of it" reading impossible to miss.

être can also go into the future, describing an action that will be in progress at a specified future moment: Demain à cette heure-ci, je serai en train de travailler. (Tomorrow at this time, I'll be [in the middle of] working.) This is less common than the present and imparfait uses, but grammatical.

What it is not

• Not a way to announce a future plan. The present-tense form, je suis en train de…, only ever describes something already in progress right now — not something not yet started. For a plan or an upcoming event, French reaches for other forms instead — most commonly the futur proche (aller + infinitive): Je vais manger ("I'm going to eat"), though plain present (Demain, je pars) and futur simple (je partirai) work too. Never ❌ Je suis en train de manger for something not yet started.
• Not a habit. ❌ Je suis en train de manger du poisson tous les vendredis is wrong for a repeated routine — plain present handles habits: ✅ Je mange du poisson tous les vendredis.

Two related constructions round out this family of periphrastic (multi-word) verb phrases, each covering a different point in time relative to "now": venir de + infinitive for something that just happened, être en train de + infinitive for something happening right now, and futur proche (aller + infinitive) for an upcoming or anticipated future action.

Common mistakes

• ❌ Je suis en train manger. → ✅ Je suis en train de manger. (don't drop de)
• ❌ Je suis en train de mange. → ✅ Je suis en train de manger. (the second verb stays in the infinitive)
• ❌ Demain, je suis en train de partir. → ✅ Demain, je vais partir. (a not-yet-started plan needs futur proche, plain present, or futur simple — never être en train de)
• ❌ Je suis en train de manger du poisson tous les vendredis. → ✅ Je mange du poisson tous les vendredis. (a habit takes the plain present, not être en train de)
• ❌ Il en train de travailler. → ✅ Il est en train de travailler. (don't drop être)

Quick check

Rewrite each sentence with être en train de to stress that the action is happening right now.

1. Elle lit un livre. (right now)
2. Nous cuisinons. (right now)
3. Tu travailles ? (right now)
4. Ils regardaient un film quand je suis arrivé. (were in the middle of, past)
5. Je finis mes devoirs. (right now)

Key takeaways

• être en train de + infinitive emphasises that an action is happening right now: je suis en train de manger.
• French's plain present tense already covers ongoing action (je mange = "I eat" or "I'm eating") — être en train de is for emphasis and clarity, not a grammatical requirement.
• en train de never changes; only être is conjugated, and the second verb stays in the infinitive.
• Put être in the imparfait to describe an action that was in progress at a past moment: j'étais en train de dormir; put it in the future to describe one that will be in progress at a future moment: je serai en train de travailler.
• The present-tense form, je suis en train de…, never expresses a future plan (French has other forms for that, most commonly futur proche, aller + infinitive) or a habit (that's plain present).
