Mastering the future tenses, the conditional mood, and conditional si clauses is vital for Leaving Certificate Higher Level French. These structures allow you to discuss education and career ambitions, make polite requests, propose solutions in discursive essays, and handle hypothetical questions confidently in both the oral and written examinations.

Le Futur Proche: Immediate Plans and Oral Fluency

The futur proche (near future) describes events that are about to happen or definite plans already decided. It corresponds directly to the English structure 'going to do something'. In everyday spoken French and the oral exam, it is the most natural tense for discussing upcoming intentions, such as your plans for the weekend or the summer holidays.

Formation

To form the futur proche, conjugate the verb aller in the present tense and place an infinitive directly after it:

  • je vais + infinitif (je vais étudier — I am going to study)
  • tu vas + infinitif (tu vas partir — you are going to leave)
  • il / elle / on va + infinitif (on va commencer — we are going to start)
  • nous allons + infinitif (nous allons voyager — we are going to travel)
  • vous allez + infinitif (vous allez voir — you are going to see)
  • ils / elles vont + infinitif (ils vont arriver — they are going to arrive)

Negation and Word Order

In negative sentences, ne and pas wrap strictly around the conjugated form of aller. The infinitive remains outside the negative structure:

  • Je ne vais pas sortir ce soir. (I am not going to go out tonight.)
  • Elle ne va pas accepter l'invitation. (She is not going to accept the invitation.)

Pronouns with the Futur Proche

Both reflexive pronouns (me, te, se, nous, vous, se) and direct or indirect object pronouns (le, la, les, lui, leur) sit immediately before the infinitive, not before aller:

  • Je vais me reposer après les examens. (I am going to rest after the exams.)
  • Nous allons nous amuser pendant les vacances. (We are going to have fun during the holidays.)
  • Je vais le faire demain. (I am going to do it tomorrow.)
  • Je ne vais pas le faire. (I am not going to do it.)

In the listening comprehension, listen carefully to distinguish the futur proche from the passé composé of partir: je vais partir (I am going to leave) sounds distinct from je suis parti (I left).

In Je ne vais pas le faire, ne and pas surround vais, while le sits directly before faire.
In Je ne vais pas le faire, ne and pas surround vais, while le sits directly before faire.

Le Futur Simple: Formation, Irregular Stems, and Time Conjunctions

The futur simple (simple future) expresses what will happen. It translates English constructions like 'I will go', 'she will succeed', or 'they will understand'. In written production—especially in opinion pieces and formal letters—it allows you to set out long-term proposals or societal predictions.

Regular Formation

Take the infinitive of the verb as your stem and add the endings: -ai, -as, -a, -ons, -ez, -ont. For verbs ending in -re, drop the final -e before adding the endings. These endings are the same for all verbs. They look like the present tense of avoir (ai, as, a, ont), except that the nous and vous forms are only -ons and -ez (not avons, avez).

Essential Irregular Stems

Many common verbs use an irregular stem in the future. Once you know the stem, attach the regular endings:

  • êtreser- (je serai — I will be)
  • avoiraur- (j'aurai — I will have)
  • allerir- (j'irai — I will go)
  • fairefer- (je ferai — I will do / make)
  • pouvoirpourr- (je pourrai — I will be able to)
  • vouloirvoudr- (je voudrai — I will want)
  • devoirdevr- (je devrai — I will have to)
  • savoirsaur- (je saurai — I will know)
  • venirviendr- (je viendrai — I will come)
  • voirverr- (je verrai — I will see)
  • envoyerenverr- (j'enverrai — I will send)
  • falloirfaudr- (il faudra — it will be necessary)
  • tenirtiendr- (je tiendrai); obtenir → (j'obtiendrai — I will obtain)
  • recevoirrecevr- (je recevrai — I will receive)
  • courircourr- (je courrai — I will run); mourir → (il mourra — he will die)
  • pleuvoirpleuvr- (il pleuvra — it will rain)

Spelling-Change Verbs

Some regular -er verbs adjust their stem before future endings:

  • Verbs with an unaccented e in the root double the consonant or take a grave accent: acheter → j'achèterai; se lever → je me lèverai; appeler → j'appellerai; jeter → je jetterai.
  • Verbs in -oyer and -uyer change y to i: nettoyer → je nettoierai. Verbs in -ayer can use i or keep y: essayer → j'essaierai; payer → je paierai (or payerai).
  • Verbs with é in the infinitive keep it: préférer → je préférerai; espérer → j'espérerai.

The Conjunction Rule: Quand, Lorsque, Dès Que, Aussitôt Que

In English, we say 'When I finish my exams, I will celebrate' using the present tense. In these examples, French uses a future tense after the conjunction as well as in the main clause:

  • Quand je serai diplômée, je chercherai un emploi. (When I graduate, I will look for a job.)
  • Dès que nous aurons les résultats, nous fêterons cela. (As soon as we have the results, we will celebrate.)
  • Lorsqu'il aura le temps, il nous aidera. (When he has time, he will help us.)
  • Aussitôt que j'arriverai à la gare, je t'appellerai. (As soon as I arrive at the station, I will call you.)

If the future action is already completed prior to another, French uses the futur antérieur: Dès que j'aurai fini mes études, je voyagerai. (As soon as I have finished my studies, I will travel.)

A schematic timeline places completion of studies after now and before travelling, linking the events to futur antérieur and futur simple.

Le Conditionnel: Formation, Register, and Spotting the Tense

The conditionnel présent translates to 'would' in English (I would go, she would help). It is indispensable in formal correspondence, opinion essays, and polite oral responses.

Formation

The conditional combines the future stem with the imperfect endings:

Future stem + imperfect endings (-ais, -ais, -ait, -ions, -iez, -aient)

  • parler → je parlerais, nous parlerions
  • être → je serais, ils seraient
  • avoir → tu aurais, vous auriez
  • faire → elle ferait, nous ferions
  • falloir → il faudrait (it would be necessary)

Polite Requests and Diplomatic Register

In requests, especially in formal letters, the conditional sounds polite and courteous rather than demanding:

  • Je veux (I want) → Je voudrais de l'aide. (I would like some help.)
  • Pouvez-vous m'aider ? → *Pourriez-vous m'aider ?* (Could you help me?)
  • Tu dois faire attention.Tu devrais faire attention. (You should be careful.)
  • Il vaut mieux agir.Il vaudrait mieux agir. (It would be better to act.)

Reported Speech (Future in the Past)

When reporting a future statement after a past reporting verb, the future tense shifts into the conditional:

  • Il a dit : « Je viendrai. »Il a dit qu'il viendrait. (He said he would come.)
  • Note: If the reporting verb is in the present, the tense does not shift: Il dit qu'il viendra. (He says he will come.)

Spotting the Tense in Reading Comprehension

Reading questions often ask you to locate a specific tense (e.g. Trouvez dans le texte un verbe au conditionnel / à l'imparfait). The conditionnel and the imparfait share the exact same endings (-ais, -ait, -ions, -iez, -aient), so check the stem:

  • Imparfait: nous-form present stem + ending (voulait, avait, finissait; être is the exception: ét-était). No -r- appears before the ending unless the infinitive stem naturally ends in r (such as préparait from préparer).
  • Conditionnel: future stem (infinitive or irregular r-stem) + ending (voudrait, aurait, serait, finirait).
  • Futur simple: future stem + future endings (voudra, aura, sera, finira).

When writing your answer, copy only the verb form itself. In past marking schemes (e.g. 2016, 2018), adding any extra word or a full clause to the answer lost all the marks for the question.

Aligned forms voulait, voudrait and voudra show the shared ending of the imperfect and conditional and the shared stem of the conditional and future.

Hypothetical Si Clauses: The Three Fixed Patterns

Conditional sentences with si (if) follow rigid grammatical pairings. Using the wrong tense in a si sentence is a common and costly grammar error, so learn the three patterns by heart.

The Rule of Si Clauses

Never put a futur simple or conditionnel straight after si when it means 'if'. After si, use only the présent, the imparfait, or the plus-que-parfait. The traditional classroom reminder is: « Les 'si' n'aiment pas les 'rai' ».

Watch out: the imparfait of verbs whose stem ends in r naturally ends in -rais (for example, si je préparais, si je rentrais, si je courais). That is completely correct because the tense is the imparfait, not the conditional.

Warning: When si means 'whether' (after verbs like demander or savoir), the future or conditional can follow: Je ne sais pas s'il viendra. (I do not know whether he will come.)

Type 1: Real and Probable Conditions

Describes a genuine possibility in the present or future.

si + présent → futur simple (or présent / impératif)

  • Si j'ai le temps ce soir, je finirai mes devoirs. (If I have time this evening, I will finish my homework.)
  • Si tu es fatigué, repose-toi. (If you are tired, rest.)
  • Si vous voulez, on peut se retrouver à 18 h. (If you want, we can meet at 6 pm.)

Type 2: Imagined or Hypothetical Situations

Expresses what would happen if circumstances were different right now. This is the pattern tested in oral hypothetical questions (Que feriez-vous si...?).

si + imparfait → conditionnel présent

  • Si j'avais plus de temps libre, je ferais du bénévolat. (If I had more free time, I would do volunteer work.)
  • Si le gouvernement investissait dans les transports, la pollution diminuerait. (If the government invested in transport, pollution would decrease.)

Type 3: Past Speculation and Unfulfilled Regrets

Describes what would have happened in the past if things had gone differently. The conditionnel passé is formed using the conditional of avoir or être + past participle (e.g. j'aurais réussi, elle serait venue).

si + plus-que-parfait → conditionnel passé

  • Si j'avais étudié plus régulièrement, j'aurais réussi tous mes examens. (If I had studied more regularly, I would have passed all my exams.)
  • Si elle était venue, nous serions sortis ensemble. (If she had come, we would have gone out together.)

Clause Reversal

You can reverse the order of the clauses in all three patterns without changing the tenses. Omit the comma when si sits in the middle:

  • Je ferais du bénévolat si j'avais plus de temps libre.

Check yourself

  1. Conjugate 'pouvoir' in the third person plural (ils / elles) of the futur simple.

    ils / elles pourront (irregular stem 'pourr-' + regular ending '-ont').

  2. In the sentence « Si elle voulait, elle pourrait venir », which verb is in the imparfait and which is in the conditionnel?

    'voulait' is in the imparfait (present nous-stem voul- + -ait); 'pourrait' is in the conditionnel (future stem pourr- + -ait).

  3. Correct this sentence: « Quand nous arrivons à Paris, nous visiterons le Louvre. »

    « Quand nous arriverons à Paris, nous visiterons le Louvre. » (French uses the futur simple after 'quand' when referring to a future action).

  4. Translate into French using a Type 2 si clause: 'If I had more money, I would buy a car.'

    « Si j'avais plus d'argent, j'achèterais une voiture. » (si + imparfait → conditionnel présent).

  5. How do you form the negative of « Je vais le faire »?

    « Je ne vais pas le faire. » ('ne' and 'pas' wrap around the conjugated form of aller; the object pronoun 'le' stays directly before the infinitive 'faire').
