empêcher — French conjugation

to prevent

Frequency#418Regular

Indicative

Present (Présent) Regular

Use the présent for habits, what is true now, and what is about to happen soon. A single set of endings covers what English often splits into “I speak” and “I am speaking”.

Elle parle arabe et français.

PronounFrenchEnglish
jeempêcheI prevent
tuempêchesyou prevent
il/elleempêchehe/she/it prevents
nousempêchonswe prevent
vousempêchezyou (pl.) prevent
ils/ellesempêchentthey prevent

Simple past (Passé simple) Regular

The passé simple narrates completed past events in a literary or very formal style. In everyday conversation people use the passé composé instead, so you mostly meet this form in books and journalism.

Ils virent le roi s'approcher.

PronounFrenchEnglish
jeempêchaiI prevented
tuempêchasyou prevented
il/elleempêchahe/she/it prevented
nousempêchâmeswe prevented
vousempêchâtesyou (pl.) prevented
ils/ellesempêchèrentthey prevented

Imperfect (Imparfait) Regular

The imparfait describes ongoing or repeated past actions and sets the background — how things were, what used to happen, weather, feelings. The passé composé, by contrast, marks single completed events.

Quand j'étais petit, j'allais souvent à la piscine.

PronounFrench
jeempêchais
tuempêchais
il/elleempêchait
nousempêchions
vousempêchiez
ils/ellesempêchaient

Conditional (Conditionnel) Regular

The conditionnel is for polite questions and requests, “would”-type hypotheticals, and what someone said would happen. It is also the usual consequent clause in si + imparfait → conditionnel patterns.

Pourriez-vous répéter, s'il vous plaît ?

PronounFrenchEnglish
jeempêcheraisI would prevent
tuempêcheraisyou would prevent
il/elleempêcheraithe/she/it would prevent
nousempêcherionswe would prevent
vousempêcheriezyou (pl.) would prevent
ils/ellesempêcheraientthey would prevent

Future (Futur) Regular

The futur is for future plans and objective predictions. In speech, aller + infinitive is often clearer for the immediate future, while the simple future is common for facts further ahead or in writing.

Demain, nous dînerons chez eux.

PronounFrenchEnglish
jeempêcheraiI will prevent
tuempêcherasyou will prevent
il/elleempêcherahe/she/it will prevent
nousempêcheronswe will prevent
vousempêcherezyou (pl.) will prevent
ils/ellesempêcherontthey will prevent

Present perfect (Passé composé) Regular

The passé composé is the main spoken past for completed, bounded actions (often with a time adverb). Use avoir with most verbs; être is required for a fixed group of motion/inchange and all pronominal verbs, with participle agreement when necessary.

Elle est venue tôt, puis elle a téléphoné.

PronounFrenchEnglish
jej'ai empêchéI have prevented
tutu as empêchéyou have prevented
il/elleil/elle a empêchéhe/she/it has prevented
nousnous avons empêchéwe have prevented
vousvous avez empêchéyou (pl.) have prevented
ils/ellesils/elles ont empêchéthey have prevented

Pluperfect (Plus-que-parfait) Regular

The plus-que-parfait is the “earlier past”: one action was already over before another past moment. It answers “had already” when a story is anchored in a past time.

Déjà, il avait fini quand je suis arrivé.

PronounFrenchEnglish
jej'avais empêchéI had prevented
tutu avais empêchéyou had prevented
il/elleil/elle avait empêchéhe/she/it had prevented
nousnous avions empêchéwe had prevented
vousvous aviez empêchéyou (pl.) had prevented
ils/ellesils/elles avaient empêchéthey had prevented

Conditional perfect (Conditionnel passé) Regular

The conditionnel passé states what would have been true, plans that failed, and unreal past if-clauses (often with si + plus-que-parfait in the apodose).

J'aurais dit oui, mais c'était impossible.

PronounFrench
jej'aurais empêché
tutu aurais empêché
il/elleil/elle aurait empêché
nousnous aurions empêché
vousvous auriez empêché
ils/ellesils/elles auraient empêché

Future perfect (Futur antérieur) Regular

The futur antérieur marks an action that will be finished before a later future moment (by then I will have…). It can also suggest a conjecture about a recent past fact in formal or literary use.

D'ici samedi, j'aurai lu le rapport.

PronounFrenchEnglish
jej'aurai empêchéI will have prevented
tutu auras empêchéyou will have prevented
il/elleil/elle aura empêchéhe/she/it will have prevented
nousnous aurons empêchéwe will have prevented
vousvous aurez empêchéyou (pl.) will have prevented
ils/ellesils/elles auront empêchéthey will have prevented

Subjunctive

Present subjunctive (Subjonctif présent) Regular

The present subjunctive appears in subordinate clauses after desire, doubt, fear, need, and many impersonals, usually when the subject of the subordinate is different. Learn common triggers: il faut que, je veux que, je doute que…

Il faut qu'il parte avant midi.

PronounFrench
jeempêche
tuempêches
il/elleempêche
nousempêchions
vousempêchiez
ils/ellesempêchent

Imperfect subjunctive (Subjonctif imparfait) Regular

The imparfait du subjonctif is a literary and formal past subjunctive. In modern speech, the present subjunctive usually replaces it for the same meaning.

Bien qu'il fût fatigué, il continua.

PronounFrench
jeempêchasse
tuempêchasses
il/elleempêchât
nousempêchassions
vousempêchassiez
ils/ellesempêchassent

Other forms

Imperative (Impératif) Regular

The imperative is for direct orders and advice to tu, nous, and vous. For many -er verbs, the tu form drops the final -s of the present (parle!); negatives use the subjunctive-like forms in practice.

Fermons la porte, s'il vous plaît !

PronounFrench
tuempêche
nousempêchons
vousempêchez
