sous-estimer — French conjugation
to underestimate
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.
| Pronoun | French | English |
|---|---|---|
| je | sous-estime | I underestimate |
| tu | sous-estimes | you underestimate |
| il/elle | sous-estime | he/she/it underestimates |
| nous | sous-estimons | we underestimate |
| vous | sous-estimez | you (pl.) underestimate |
| ils/elles | sous-estiment | they underestimate |
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 | sous-estimai | I underestimated |
| tu | sous-estimas | you underestimated |
| il/elle | sous-estima | he/she/it underestimated |
| nous | sous-estimâmes | we underestimated |
| vous | sous-estimâtes | you (pl.) underestimated |
| ils/elles | sous-estimèrent | they underestimated |
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 | sous-estimais |
| tu | sous-estimais |
| il/elle | sous-estimait |
| nous | sous-estimions |
| vous | sous-estimiez |
| ils/elles | sous-estimaient |
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 | sous-estimerais | I would underestimate |
| tu | sous-estimerais | you would underestimate |
| il/elle | sous-estimerait | he/she/it would underestimate |
| nous | sous-estimerions | we would underestimate |
| vous | sous-estimeriez | you (pl.) would underestimate |
| ils/elles | sous-estimeraient | they would underestimate |
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 | sous-estimerai | I will underestimate |
| tu | sous-estimeras | you will underestimate |
| il/elle | sous-estimera | he/she/it will underestimate |
| nous | sous-estimerons | we will underestimate |
| vous | sous-estimerez | you (pl.) will underestimate |
| ils/elles | sous-estimeront | they will underestimate |
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 sous-estimé | I have underestimated |
| tu | tu as sous-estimé | you have underestimated |
| il/elle | il/elle a sous-estimé | he/she/it has underestimated |
| nous | nous avons sous-estimé | we have underestimated |
| vous | vous avez sous-estimé | you (pl.) have underestimated |
| ils/elles | ils/elles ont sous-estimé | they have underestimated |
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 sous-estimé | I had underestimated |
| tu | tu avais sous-estimé | you had underestimated |
| il/elle | il/elle avait sous-estimé | he/she/it had underestimated |
| nous | nous avions sous-estimé | we had underestimated |
| vous | vous aviez sous-estimé | you (pl.) had underestimated |
| ils/elles | ils/elles avaient sous-estimé | they had underestimated |
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 sous-estimé |
| tu | tu aurais sous-estimé |
| il/elle | il/elle aurait sous-estimé |
| nous | nous aurions sous-estimé |
| vous | vous auriez sous-estimé |
| ils/elles | ils/elles auraient sous-estimé |
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 sous-estimé | I will have underestimated |
| tu | tu auras sous-estimé | you will have underestimated |
| il/elle | il/elle aura sous-estimé | he/she/it will have underestimated |
| nous | nous aurons sous-estimé | we will have underestimated |
| vous | vous aurez sous-estimé | you (pl.) will have underestimated |
| ils/elles | ils/elles auront sous-estimé | they will have underestimated |
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.
| Pronoun | French |
|---|---|
| je | sous-estime |
| tu | sous-estimes |
| il/elle | sous-estime |
| nous | sous-estimions |
| vous | sous-estimiez |
| ils/elles | sous-estiment |
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 | sous-estimasse |
| tu | sous-estimasses |
| il/elle | sous-estimât |
| nous | sous-estimassions |
| vous | sous-estimassiez |
| ils/elles | sous-estimassent |
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 | sous-estime |
| nous | sous-estimons |
| vous | sous-estimez |
