subir — French conjugation

to undergo

Frequency#553Regular

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
jesubisI undergo
tusubisyou undergo

noussubissonswe undergo
voussubissezyou (pl.) undergo
ils/ellessubissentthey undergo

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
jesubisI underwent
tusubisyou underwent
il/ellesubithe/she/it underwent
noussubîmeswe underwent
voussubîtesyou (pl.) underwent
ils/ellessubirentthey underwent

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
jesubissais
tusubissais
il/ellesubissait
noussubissions
voussubissiez
ils/ellessubissaient

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
jesubiraisI would undergo
tusubiraisyou would undergo
il/ellesubiraithe/she/it would undergo
noussubirionswe would undergo
voussubiriezyou (pl.) would undergo
ils/ellessubiraientthey would undergo

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
jesubiraiI will undergo
tusubirasyou will undergo
il/ellesubirahe/she/it will undergo
noussubironswe will undergo
voussubirezyou (pl.) will undergo
ils/ellessubirontthey will undergo

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 subiI have undergone
tutu as subiyou have undergone
il/elleil/elle a subihe/she/it has undergone
nousnous avons subiwe have undergone
vousvous avez subiyou (pl.) have undergone
ils/ellesils/elles ont subithey have undergone

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 subiI had undergone
tutu avais subiyou had undergone
il/elleil/elle avait subihe/she/it had undergone
nousnous avions subiwe had undergone
vousvous aviez subiyou (pl.) had undergone
ils/ellesils/elles avaient subithey had undergone

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 subi
tutu aurais subi
il/elleil/elle aurait subi
nousnous aurions subi
vousvous auriez subi
ils/ellesils/elles auraient subi

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 subiI will have undergone
tutu auras subiyou will have undergone
il/elleil/elle aura subihe/she/it will have undergone
nousnous aurons subiwe will have undergone
vousvous aurez subiyou (pl.) will have undergone
ils/ellesils/elles auront subithey will have undergone

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
jesubisse
tusubisses
il/ellesubisse
noussubissions
voussubissiez
ils/ellessubissent

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
jesubisse
tusubisses
il/ellesubît
noussubissions
voussubissiez
ils/ellessubissent

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
tusubis
noussubissons
voussubissez
