interférer — French conjugation
to interfere
Indicative
Present (Présent) Irregular
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.
| Pronoun | French | English |
|---|---|---|
| je | interfère | I interfere |
| tu | interfères | you interfere |
| il/elle | interfère | he/she/it interferes |
| nous | interférons | we interfere |
| vous | interférez | you (pl.) interfere |
| ils/elles | interfèrent | they interfere |
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.
| Pronoun | French | English |
|---|---|---|
| je | interférai | I interfered |
| tu | interféras | you interfered |
| il/elle | interféra | he/she/it interfered |
| nous | interférâmes | we interfered |
| vous | interférâtes | you (pl.) interfered |
| ils/elles | interférèrent | they interfered |
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.
| Pronoun | French |
|---|---|
| je | interférais |
| tu | interférais |
| il/elle | interférait |
| nous | interférions |
| vous | interfériez |
| ils/elles | interféraient |
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 ?
| Pronoun | French | English |
|---|---|---|
| je | interférerais | I would interfere |
| tu | interférerais | you would interfere |
| il/elle | interférerait | he/she/it would interfere |
| nous | interférerions | we would interfere |
| vous | interféreriez | you (pl.) would interfere |
| ils/elles | interféreraient | they would interfere |
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.
| Pronoun | French | English |
|---|---|---|
| je | interférerai | I will interfere |
| tu | interféreras | you will interfere |
| il/elle | interférera | he/she/it will interfere |
| nous | interférerons | we will interfere |
| vous | interférerez | you (pl.) will interfere |
| ils/elles | interféreront | they will interfere |
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.
| Pronoun | French | English |
|---|---|---|
| je | j'ai interféré | I have interfered |
| tu | tu as interféré | you have interfered |
| il/elle | il/elle a interféré | he/she/it has interfered |
| nous | nous avons interféré | we have interfered |
| vous | vous avez interféré | you (pl.) have interfered |
| ils/elles | ils/elles ont interféré | they have interfered |
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.
| Pronoun | French | English |
|---|---|---|
| je | j'avais interféré | I had interfered |
| tu | tu avais interféré | you had interfered |
| il/elle | il/elle avait interféré | he/she/it had interfered |
| nous | nous avions interféré | we had interfered |
| vous | vous aviez interféré | you (pl.) had interfered |
| ils/elles | ils/elles avaient interféré | they had interfered |
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.
| Pronoun | French |
|---|---|
| je | j'aurais interféré |
| tu | tu aurais interféré |
| il/elle | il/elle aurait interféré |
| nous | nous aurions interféré |
| vous | vous auriez interféré |
| ils/elles | ils/elles auraient interféré |
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.
| Pronoun | French | English |
|---|---|---|
| je | j'aurai interféré | I will have interfered |
| tu | tu auras interféré | you will have interfered |
| il/elle | il/elle aura interféré | he/she/it will have interfered |
| nous | nous aurons interféré | we will have interfered |
| vous | vous aurez interféré | you (pl.) will have interfered |
| ils/elles | ils/elles auront interféré | they will have interfered |
Subjunctive
Present subjunctive (Subjonctif présent) Irregular
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.
| Pronoun | French |
|---|---|
| je | interfère |
| tu | interfères |
| il/elle | interfère |
| nous | interférions |
| vous | interfériez |
| ils/elles | interfèrent |
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.
| Pronoun | French |
|---|---|
| je | interférasse |
| tu | interférasses |
| il/elle | interférât |
| nous | interférassions |
| vous | interférassiez |
| ils/elles | interférassent |
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 !
| Pronoun | French |
|---|---|
| tu | interfère |
| nous | interférons |
| vous | interférez |
