Grammar Rule in 30 Seconds

Irregular conditional stems use the same base as the future tense, followed by imparfait endings.

  • Identify the irregular stem (e.g., 'ser-' for être).
  • Add the conditional endings: -ais, -ais, -ait, -ions, -iez, -aient.
  • Remember: the stem is the same for all persons.
Irregular Stem + Imparfait Ending = Conditional Verb

Overview

The French conditionnel présent is a grammatical mood that allows speakers to express actions or states that are hypothetical, uncertain, or dependent on certain conditions. Unlike a tense, which describes *when* an action occurs, a mood conveys the speaker's attitude toward the action. At the A1 CEFR level, you will primarily encounter and use the conditional to express politeness and desire, often translating to would, could, or should in English.
This mood is fundamental for softening requests, offering advice, and articulating preferences without sounding abrupt or demanding.
While many French verbs form their conditional in a predictable manner, a crucial set of highly frequent verbs deviate from this regular pattern. These are the irregular conditional verbs. Instead of using their infinitive as a base, they adopt a unique, irregular stem that must be committed to memory.
Mastering these irregular stems is not merely an academic exercise; it is essential for fluent and natural communication. Without them, you would struggle to form polite requests like Je voudrais (I would like) or offer gentle suggestions such as Tu devrais (You should). These irregular stems are a cornerstone of everyday French discourse, enabling you to navigate social interactions with nuance and express a broader range of intentions.
Understanding the origin and application of these irregular forms provides insight into the structure of the French language and significantly enhances your communicative competence, even at a beginner stage. Crucially, these irregular stems are identical to those used for the futur simple (simple future tense), meaning that learning them once unlocks conjugation for two major grammatical forms.

How This Grammar Works

The conditionnel présent functions as a bridge between expressing definite facts and purely imaginary scenarios. Linguistically, it is a synthesized form, meaning it is constructed by attaching endings directly to a verb stem, rather than using an auxiliary verb. Its structure provides a linguistic clue to its meaning: it borrows the stems from the futur simple (future simple tense) and the endings from the imparfait (imperfect past tense).
This unique combination imbues the conditional with a sense of potentiality, deference, and unreality, distinct from both the certainty of the future and the descriptive nature of the past.
The irregularity in these verbs stems from their historical development, often tracing back to Latin roots that evolved differently than those of regular verbs. For regular verbs, the stem for the conditional (and future simple) is simply the verb's infinitive form (e.g., parler \u2192 parler-). However, for irregular verbs, the infinitive undergoes a significant change, resulting in a distinct, often shortened or altered, stem.
A defining characteristic of all conditional stems, both regular and irregular, is that they always end in the letter r. This r sound is a critical phonetic marker that signals to a native speaker that the verb is in either the future simple or the conditional mood. If you omit this r, you are likely conjugating the verb in the imperfect tense, drastically changing the meaning from a hypothetical would do to a descriptive used to do or was doing. For instance, j'aurais (I would have) contrasts sharply with j'avais (I had/used to have).
Recognizing and correctly producing this r is paramount. The conditional endings, -ais, -ais, -ait, -ions, -iez, -aient, are identical to the endings of the imperfect tense for regular verbs, creating a familiar pattern once the irregular stem is identified. This consistent pattern simplifies conjugation once the initial stem is memorized.

Formation Pattern

1
Conjugating an irregular verb in the conditionnel présent involves a straightforward two-step process, provided you know the specific irregular stem for the verb in question. This pattern remains consistent for all irregular verbs, making it highly predictable once the initial memorization is complete.
2
Identify the Irregular Stem: For each irregular verb, there is a unique stem used for both the futur simple and the conditionnel présent. This stem is often a phonetic reduction or alteration of the infinitive, and crucially, it always ends in r. There are no exceptions to this r ending for conditional stems. For example, aller (to go) transforms into ir-, avoir (to have) becomes aur-, and être (to be) changes to ser-. Memorizing these stems is the primary challenge; once you know them, the rest of the conjugation is automatic. For some verbs like courir or mourir, a double r appears in the stem to maintain pronunciation consistency.
3
Add the Conditional Endings: Once you have the correct irregular stem, you attach the standard conditional endings directly to it. These endings are invariant, meaning they do not change regardless of which irregular verb you are conjugating. They are derived from the imperfect tense endings and consistently indicate the subject pronoun.
4
Here is a table summarizing the most common irregular stems you will encounter at the A1 level, along with their infinitive forms and English meanings:
5
| Infinitive | Irregular Stem | Meaning |
6
| :--------- | :------------- | :------------- |
7
| aller | ir- | to go |
8
| avoir | aur- | to have |
9
| courir | courr- | to run |
10
| devoir | devr- | to have to |
11
| envoyer | enverr- | to send |
12
| être | ser- | to be |\
13
| faire | fer- | to do/make |
14
| mourir | mourr- | to die |
15
| pouvoir | pourr- | to be able to |
16
| recevoir | recevr- | to receive |
17
| savoir | saur- | to know |
18
| tenir | tiendr- | to hold |
19
| venir | viendr- | to come |
20
| voir | verr- | to see |
21
| vouloir | voudr- | to want |
22
And here are the standard conditional endings that you append to any of these stems:
23
| Subject Pronoun | Conditional Ending |
24
| :-------------- | :----------------- |
25
| je | -ais |
26
| tu | -ais |
27
| il/elle/on | -ait |
28
| nous | -ions |
29
| vous | -iez |
30
| ils/elles | -aient |
31
Observe that the endings for je, tu, and il/elle/on are phonetically identical, all pronounced similarly to the English eh or ay sound (/ɛ/). The ending for ils/elles, -aient, is also silent, meaning ils seraient sounds exactly like il serait. This phonetic convergence simplifies spoken French, though careful attention to written forms is necessary to distinguish subjects. The nous and vous forms have distinct pronunciations due to the visible -ions and -iez endings.

When To Use It

The conditionnel présent serves several crucial functions in French, particularly enhancing politeness, expressing possibility, and discussing hypothetical scenarios. At the A1 level, mastering its application in these contexts will significantly improve your ability to interact effectively in French.
  1. 1Polite Requests and Desires: This is perhaps the most fundamental and frequently used function for beginners. Using the conditional softens a request, making it more courteous and less demanding than a direct statement in the present tense. This is especially true in French culture, where direct requests can sometimes be perceived as abrupt or impolite.
  • Je voudrais un café, s'il vous plaît. (I would like a coffee, please.) \u2013 Much politer than Je veux un café. (I want a coffee.)
  • Pourriez-vous m'aider ? (Could you help me?) \u2013 More deferential than Pouvez-vous m'aider ? (Can you help me?)
  • Nous aimerions visiter le Louvre. (We would like to visit the Louvre.)
  1. 1Giving Advice or Suggestions: The conditional, especially with the verb devoir (to have to), allows you to offer advice or recommendations in a gentle, non-authoritative manner. This translates directly to should in English. It presents an option rather than a command.
  • Tu devrais te reposer. (You should rest.)
  • Vous devriez parler au professeur. (You should speak to the professor.)
  • Il faudrait faire plus attention. (It would be necessary to pay more attention.) \u2013 Note falloir is an impersonal verb always conjugated with il.
  1. 1Expressing Hypothetical or Imaginary Situations (Simple Conditional Clause): At A1, this typically involves simple if...then statements, where the condition is not yet fulfilled or is purely imaginary. The structure Si + Imparfait, Conditionnel is key here, connecting a past condition to a present hypothetical outcome.
  • Si j'avais le temps, je lirais ce livre. (If I had the time, I would read this book.) \u2013 A classic construction where avais is in the imperfect.
  • Ce serait formidable ! (That would be wonderful!) \u2013 Expressing an opinion about a hypothetical outcome without explicitly stating the condition.
  • Je ferais la même chose. (I would do the same thing.)
  1. 1Reporting Information with Uncertainty: When you are relaying information that you cannot confirm as fact, or when you wish to distance yourself from the absolute truth of a statement, the conditional is appropriate. This is less common at A1 but appears in phrases indicating supposition or alleged events.
  • Selon les rumeurs, il serait riche. (According to rumors, he would be rich / he is supposedly rich.)
  • L'accident aurait eu lieu hier soir. (The accident would have taken place last night / allegedly took place last night.) \u2013 This uses the past conditional, a more advanced form, but demonstrates the mood's function for reported speech.
Using the conditional appropriately adds a layer of sophistication and nuance to your French. It demonstrates an understanding of social conventions and allows for more indirect and polite communication, which is highly valued in French culture. This deliberate choice of mood signals respect and thoughtful consideration in your interactions.

Common Mistakes

Learners frequently encounter specific challenges when using the irregular conditional. Awareness of these common pitfalls and understanding their underlying causes can significantly accelerate your mastery.
  1. 1Omitting the r in the Stem: This is arguably the most prevalent error. Beginners sometimes revert to the infinitive or the imperfect stem, forgetting that all conditional stems must end in r. This r is the signature of the conditional and future tenses.
  • Incorrect: Je voulais un café. (I wanted a coffee.)
  • Correct: Je voudrais un café. (I would like a coffee.)
  • Explanation: voulais is the imperfect form of vouloir. The r in voudrais is what signals the conditional mood. Without it, you are speaking in the past, completely changing the meaning from a polite desire to a past event.
  1. 1Using the Infinitive for Irregular Verbs: Attempting to conjugate irregular verbs by simply adding conditional endings to their infinitive form. This works for regular verbs, but not for the specific irregular ones.
  • Incorrect: J'allerais à Paris.
  • Correct: J'irais à Paris. (I would go to Paris.)
  • Explanation: aller is an irregular verb; its conditional stem is ir-, not aller-. This requires memorization of the specific irregular stems. The incorrect form, allerais, sounds distinctly unnatural to a native speaker and immediately signals a non-native speaker.
  1. 1Confusing Conditional and Future Simple Endings: While the stems are identical for both, the endings differ, particularly for je and tu. This subtle distinction is crucial.
  • Conditional (-ais): Je ferais (I would do)
  • Future Simple (-ai): Je ferai (I will do)
  • Explanation: The subtle difference in ending (-ais vs. -ai) carries a significant difference in meaning (hypothetical vs. definite future). This distinction is critical for conveying your intention accurately. In speech, the difference might be minimal, but in writing, it is distinct and non-negotiable for correct meaning.
  1. 1Mispronouncing Endings: Specifically, not pronouncing the i in -ions and -iez, or over-pronouncing silent letters. This can lead to confusion with other tenses.
  • Incorrect Pronunciation: Saying nous serons instead of nous serions.
  • Correct Pronunciation: nous serions (noo seh-ree-ohn) vs. nous serons (noo seh-rohn).
  • Explanation: The i in -ions and -iez is crucial; its omission makes the conditional sound like the future simple (nous serons is the future form). Conversely, remember that the -s, -t, and -ent in forms like je ferais, il ferait, and ils feraient are silent. Over-pronouncing them will sound unnatural.
  1. 1Overuse or Underuse of Politeness: Not recognizing when the conditional is culturally expected for politeness, or using it excessively in contexts where directness is acceptable. This often comes down to cultural sensitivity.
  • Underuse (abrupt): Je veux ça. (I want that.)
  • Appropriate use: Je voudrais ça. (I would like that.)
  • Explanation: French culture often values indirectness in requests, particularly in public or formal settings. Using Je voudrais is a standard politeness marker, whereas Je veux can sound impolite or childish in many situations, especially with strangers or service personnel.
  1. 1Incorrectly forming negative or interrogative sentences: Forgetting to place ne...pas around the conjugated verb, or incorrect inversion in questions.
  • Negative: Je ne serais pas là. (I would not be there.)
  • Interrogative (inversion): Seriez-vous libre ? (Would you be free?)
  • Explanation: The conditional verb behaves like any other conjugated verb in terms of negation and inversion. The ne...pas structure always surrounds the finite verb, and inversion places the verb before the subject pronoun with a hyphen.
By focusing on the irregular stems and being mindful of the distinct endings, pronunciations, and social contexts, you can avoid these common errors and express yourself more accurately and confidently in French.

Contrast With Similar Patterns

Understanding the conditionnel présent is often clarified by contrasting it with other grammatically similar French tenses and moods. While they might share certain structural elements or sound similar, their functions and meanings are distinct. This section will highlight these critical differences.
  1. 1Conditionnel Présent vs. Futur Simple: These two forms are closely related, sharing the same irregular stems, but they convey fundamentally different attitudes towards an action.
  • Shared Feature: Both use the exact same irregular stems (e.g., ir-, aur-, ser-). This is a key memory aid; once you know the stem, you are halfway to conjugating both.
  • Distinguishing Feature: They use different sets of endings, which dictate their meaning. The future simple expresses certainty or a definite plan in the future, while the conditional expresses hypothesis, desire, or politeness.
| Verb | Conditional (would) | Future Simple (will) | Meaning Distinction |
| :------- | :------------------------ | :------------------------ | :-------------------------------------------------- |
| faire | Je ferais | Je ferai | I would do (hypothetical) / I will do (certain) |
| avoir | Nous aurions | Nous aurons | We would have (desire) / We will have (future event)|
| aller | Vous iriez | Vous irez | You would go (conditional) / You will go (future plan)|
  • Example: Je ferai mes devoirs ce soir. (I will do my homework tonight. \u2013 *A definite plan, a promise.*) vs. Je ferais mes devoirs si j'avais le temps. (I would do my homework if I had the time. \u2013 *A hypothetical situation, the condition is not met.*)
  • Linguistic Insight: The conditional endings, being derived from the imperfect, lend a softness or uncertainty compared to the more definitive future simple endings, which are historically linked to Latin present tense forms of habere (to have). This historical connection helps explain the difference in modal meaning.
  1. 1Conditionnel Présent vs. Imparfait (Imperfect Past): While phonetically similar for some forms due to shared endings, their stems and meanings are entirely different.
  • Shared Feature: Both use the same set of endings (-ais, -ais, -ait, -ions, -iez, -aient). This is where confusion often arises, especially when relying solely on sound.
  • Distinguishing Feature: They use different stems and convey different temporal references. The imperfect describes past habits, ongoing actions, or descriptions in the past, while the conditional expresses hypothetical actions or politeness relating to the present or future.
| Verb | Conditional (would) | Imparfait (was/used to) | Meaning Distinction |
| :------ | :-------------------------- | :-------------------------- | :----------------------------------------------------- |
| être | Il serait | Il était | He would be (hypothetical) / He was (past description)|
| avoir | J'aurais | J'avais | I would have (desire) / I had (past possession) |
| aller | Ils iraient | Ils allaient | They would go (hypothetical) / They were going (past action)|
  • Example: Quand j'étais petit, j'allais souvent à la plage. (When I was little, I used to go often to the beach. \u2013 *Past habit.*) vs. Si j'avais une voiture, j'irais à la plage. (If I had a car, I would go to the beach. \u2013 *Hypothetical situation, condition not met.*)
  • Linguistic Insight: The stem difference is crucial here. The imperfect uses the present tense nous form stem (e.g., allons \u2192 all-), whereas the conditional uses the irregular future stem (e.g., ir-). Relying solely on the endings to distinguish these two is a common error; the stem provides the primary disambiguation.
  1. 1Conditionnel Présent vs. Présent de l'Indicatif (Present Tense): The most direct contrast, highlighting the core function of politeness and hypothesis.
  • Distinguishing Feature: The present tense describes facts, current actions, or habitual actions with certainty. The conditional introduces politeness, desire, advice, or hypothesis, tempering directness with deference or possibility.
  • Example: Je veux manger. (I want to eat. \u2013 *Direct, assertive, potentially abrupt.*) vs. Je voudrais manger. (I would like to eat. \u2013 *Polite request, standard in social interaction.*)
  • Example: Tu peux m'aider. (You can help me. \u2013 *Statement of ability or direct question.*) vs. Tu pourrais m'aider. (You could help me. \u2013 *Gentle suggestion or request.*)
  • Cultural Insight: In French communication, opting for the conditional over the present tense in requests or suggestions often demonstrates respect and refinement. This is particularly important when interacting with strangers, in formal settings, or when making potentially inconvenient requests. It signals consideration for the interlocutor.
Mastering these distinctions is key to both correctly conjugating and appropriately employing the conditional mood in French, allowing for precise and culturally sensitive expression.

Real Conversations

The conditionnel présent, particularly its irregular forms, permeates everyday French communication, extending beyond formal speech into casual exchanges, digital messaging, and professional interactions. Observing its use in context illuminates its practical utility and the nuance it adds to language.

1. Ordering and Services (Politeness):

- In a café: The conditional is almost universally used for ordering to maintain politeness.

- Bonjour, je voudrais un croissant et un café, s'il vous plaît. (Hello, I would like a croissant and a coffee, please.)

- Madame, nous pourrions avoir l'addition ? (Madam, could we have the bill?) \u2013 Note the nous for politeness even if one person is speaking.

- On the phone to customer service: This context demands deference.

- Je devrais modifier ma réservation. (I should modify my reservation.)

- Serait-il possible de parler à un responsable ? (Would it be possible to speak to a manager?) \u2013 A classic indirect question.

2. Giving Advice/Suggestions (Friend to friend/colleague): The conditional softens advice, making it less confrontational.

- Text message: Informal yet still polite.

- Salut ! Pour ton examen, tu devrais relire tes notes. Et tu pourrais aussi faire des exercices en ligne. (Hi! For your exam, you should re-read your notes. And you could also do some exercises online.)

- Si j'étais toi, je n'irais pas à cette fête. (If I were you, I wouldn't go to that party.) \u2013 Common expression for advice.

3. Discussing Hypotheticals/Dreams (Casual chat): This is where imagination takes linguistic form.

- Si on gagnait au loto, on ferait le tour du monde ! (If we won the lottery, we would travel around the world!) \u2013 A common daydream scenario.

- J'aimerais tellement vivre au bord de la mer. Ce serait incroyable ! (I would love to live by the sea. That would be incredible!) \u2013 Expressing personal desire and a hypothetical outcome.

- Tu auras des nouvelles bientôt ? J'espère, mais je ne saurais pas dire quand. (You will have news soon? I hope so, but I wouldn't know when to say.) \u2013 Je ne saurais pas is a common polite and slightly humble way of saying "I don't know."

4. Professional Emails (Formal politeness): The conditional is standard for formal communication.

- Nous serions ravis de vous accueillir pour une réunion. (We would be delighted to welcome you for a meeting.) \u2013 Standard polite phrasing.

- Je pourrais vous envoyer les documents nécessaires d'ici demain. (I could send you the necessary documents by tomorrow.) \u2013 Offering a service politely.

- Cela devrait résoudre le problème. (That should resolve the problem.) \u2013 Expressing expectation with a degree of caution.

In these examples, the irregular conditional softens commands, transforms desires into polite requests, and frames possibilities as suggestions rather than demands. Observe the nuanced impact of je voudrais versus je veux when ordering, or tu devrais versus tu dois (you must) when advising. This subtle shift in modality is a hallmark of sophisticated French communication, even at foundational levels. The French language, in many contexts, favors an indirect approach, and the conditional is a primary tool for achieving this. Mastering these usages ensures you navigate French social dynamics effectively.

Progressive Practice

1

Mastering the irregular conditional requires consistent, structured practice that builds from recognition to active production. Focus on the most common irregular verbs first, then gradually expand your repertoire. Repetition and contextual application are key.

2

Phase 1: Recognition and Stem Memorization (Focus on Input)

3

- Flashcards: Create physical or digital flashcards for the key irregular infinitives and their corresponding conditional stems. The front should have the infinitive, and the back the stem. Always include the r at the end of the stem.

4

- Front: aller \u2192 Back: ir-

5

- Front: vouloir \u2192 Back: voudr-

6

- Listen and Identify: Actively listen to French audio (songs, podcasts, simple dialogues, news reports) and try to identify conditional forms. Pay close attention to the r sound and the endings. Can you differentiate serai (future) from serais (conditional) by context or subtle phonetic cues? This trains your ear.

7

- Matching Exercises: Practice matching irregular infinitives with their correct conditional stems. This reinforces the visual connection. Create lists where you have to draw lines connecting the infinitive to its stem.

8

Phase 2: Controlled Conjugation (Focus on Output, but Guided)

9

- Systematic Conjugation Drills: Take a list of irregular infinitives (e.g., avoir, être, faire, pouvoir, vouloir, devoir, aller) and systematically conjugate them for all six subject pronouns in the conditional present. Write them out fully to reinforce the visual pattern and muscle memory.

10

- Example for faire: je ferais, tu ferais, il ferait, nous ferions, vous feriez, ils feraient.

11

- Fill-in-the-Blanks: Practice completing sentences with the correct irregular conditional form. This tests your understanding of both stem and ending.

12

- Si j'avais le choix, je ______ (aller) à la plage. \u2192 Si j'avais le choix, j'irais à la plage.

13

- Nous ______ (devoir) étudier davantage. \u2192 Nous devrions étudier davantage.

14

- Negative and Interrogative: Practice forming negative and interrogative sentences with these conjugated verbs. Ensure the ne...pas placement and inversion are correct.

15

- Tu ne voudrais pas venir ? (Wouldn't you like to come?)

16

- Que feriez-vous ? (What would you do?)

17

Phase 3: Active Production and Application (Focus on Real-World Use)

18

- Sentence Building: Create your own sentences using the irregular conditional based on prompts. Start with simple desires and polite requests, then move to hypothetical situations.

Using future instead of conditional in reported speech.

Je serais allé si j'aurais su

Je serais allé si j'avais su

Using conditional in the 'si' clause.

Il faudrait que tu viendras

Il faudrait que tu viennes

Conditional triggers subjunctive, not future.

Le ministre serait en fuite (without evidence)

Le ministre serait en fuite (with journalistic distance)

Misuse of conditional for unverified info.

Je ne saurais pas quoi faire

Je ne saurais quoi faire

Redundant 'pas' with 'savoir' in formal register.

💡

寻找字母 R

如果你在动词结尾前没听到 R 的音,那它就不是条件式。R 是你表达“想要、会、可能”的信号:
Je mangerais bien quelque chose.
⚠️

将来 vs 条件

在口语中,je serai(将来)和 je serais(条件)听起来几乎一样。要靠语境判断是计划还是梦想。
💬

别太“生硬”

法国人非常看重礼貌。在店里说 Je veux 会显得很没礼貌,永远记得用 Je voudrais 来让沟通更顺滑。

Smart Tips

Always use 'Je voudrais' instead of 'Je veux'.

Je veux un café. Je voudrais un café.

Check if it's in the 'SAFIA' list.

Je voulerais... Je voudrais...

Use the conditional if the original speech was in the future.

Il a dit qu'il viendra. Il a dit qu'il viendrait.

Remember: 'Si' + imparfait = conditional.

Si j'aurais le temps, je viendrais. Si j'avais le temps, je viendrais.

发音

/ɛ/

Ending -ais/-ait

Pronounced like 'è' (open e).

/jɔ̃/ /je/

Ending -ions/-iez

Pronounced clearly with a nasal 'on' or 'i-é'.

Polite Request

Pourriez-vous m'aider ? ↗

Rising intonation at the end signals a polite question.

记住它

记忆技巧

Remember the 'VIP' stems: Avoir (aur), Être (ser), Faire (fer), Aller (ir). They are the same as the future tense!

视觉联想

Imagine a 'Future' train station. The same train (the stem) leaves for two different destinations: the 'Certainty' city (future) and the 'Hypothetical' city (conditional).

Rhyme

Pour le conditionnel, c'est très facile, prends le radical, ajoute -ais, -ais, -ait, -ions, -iez, -aient, c'est utile !

Story

Imagine you are a king. You say 'Je voudrais' (I would like) to your servants. You use 'serais' (would be) to describe your dream castle. You use 'pourrais' (could) to describe your powers. Everything you say is a dream, so you use the conditional.

文化笔记

Politeness is paramount. Using the conditional is the standard way to show respect in public spaces.

The conditional is often used in the same way, but sometimes speakers use 'aimerais' instead of 'voudrais' for extreme politeness.

The conditional is used similarly to France, but often with more elaborate polite phrases.

The conditional mood evolved from the Latin future perfect and the infinitive + imperfect of 'habere' (to have).

对话开场白

Si vous aviez un million d'euros, que feriez-vous ?

Pourriez-vous me dire où se trouve la gare ?

Que diriez-vous à votre moi de 10 ans ?

Si vous pouviez voyager n'importe où, où iriez-vous ?

日记主题

Write about your dream vacation using the conditional.
Describe how your life would be different if you lived in Paris.
Write a polite email to a professor asking for an extension.
Reflect on a past mistake: what would you have done differently?

常见问题 (8)

It's a historical evolution; both tenses developed from the infinitive + 'habere'.

No, only for hypothesis, politeness, and future-in-the-past.

Yes, it's the standard polite form for requests.

Try to remember the 'SAFIA' acronym: Ser, Aur, Fer, Ir, Aur.

It's neutral-to-formal; it's the standard way to be polite.

Use 'ne' + verb + 'pas'.

Yes, but never directly after 'si'.

Because it expresses actions conditional on other circumstances.
