vaciller — French conjugation
to sway
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”.

| Pronoun | French | English |
|---|---|---|

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.

| Pronoun | French | English |
|---|---|---|

| ils/elles | vacillèrent | they swayed |
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 | vacillais |
| tu | vacillais |
| il/elle | vacillait |
| nous | vacillions |
| vous | vacilliez |
| ils/elles | vacillaient |
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 | vacillerais | I would sway |
| tu | vacillerais | you would sway |
| il/elle | vacillerait | he/she/it would sway |
| nous | vacillerions | we would sway |
| vous | vacilleriez | you (pl.) would sway |
| ils/elles | vacilleraient | they would sway |
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 | vacillerai | I will sway |
| tu | vacilleras | you will sway |

| vous | vacillerez | you (pl.) will sway |
| ils/elles | vacilleront | they will sway |
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.

| Pronoun | French | English |
|---|---|---|

| ils/elles | ils/elles ont vacillé | they have swayed |
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 vacillé | I had swayed |
| tu | tu avais vacillé | you had swayed |

| nous | nous avions vacillé | we had swayed |
| vous | vous aviez vacillé | you (pl.) had swayed |
| ils/elles | ils/elles avaient vacillé | they had swayed |
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 vacillé |
| tu | tu aurais vacillé |
| il/elle | il/elle aurait vacillé |
| nous | nous aurions vacillé |
| vous | vous auriez vacillé |
| ils/elles | ils/elles auraient vacillé |
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 vacillé | I will have swayed |
| tu | tu auras vacillé | you will have swayed |

| ils/elles | ils/elles auront vacillé | they will have swayed |
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 | vacille |
| tu | vacilles |
| il/elle | vacille |
| nous | vacillions |
| vous | vacilliez |
| ils/elles | vacillent |
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 | vacillasse |
| tu | vacillasses |
| il/elle | vacillât |
| nous | vacillassions |
| vous | vacillassiez |
| ils/elles | vacillassent |
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 | vacille |
| nous | vacillons |
| vous | vacillez |
