This cheat sheet covers the French future simple and conditional tenses, two forms that help students talk about what will happen and what would happen. Students need these tenses to understand stories, conversations, plans, polite requests, and hypothetical situations. The reference connects both tenses so learners can see how their stems and endings are related.
It is especially useful for reviewing conjugation patterns before writing or speaking tasks.
The future simple usually uses the infinitive as the stem plus endings like -ai, -as, -a, -ons, -ez, and -ont. The conditional usually uses the same future stem plus imperfect endings like -ais, -ais, -ait, -ions, -iez, and -aient. Many common verbs have irregular stems that are shared by both tenses, such as ser-, aur-, ir-, fer-, and verr-.
Si clauses follow set tense patterns, such as si + present with future and si + imperfect with conditional.
Key Facts
- The future simple is formed with future stem + -ai, -as, -a, -ons, -ez, -ont.
- For most -er and -ir verbs, the future stem is the infinitive, as in parlerai, finirons, and choisirez.
- For regular -re verbs, remove the final e before adding future endings, as in vendre + ai = vendrai.
- The conditional is formed with the same future stem + -ais, -ais, -ait, -ions, -iez, -aient.
- The future simple means will do something, as in je voyagerai = I will travel.
- The conditional means would do something or could be used for polite requests, as in je voudrais = I would like.
- Common shared irregular stems include être = ser-, avoir = aur-, aller = ir-, faire = fer-, venir = viendr-, pouvoir = pourr-, vouloir = voudr-, and voir = verr-.
- A common si clause pattern is si + present, then future, as in Si j'étudie, je réussirai.
Vocabulary
- Future simple
- A French tense used to say what will happen in the future.
- Conditional
- A French mood used to say what would happen, to make polite requests, or to express hypothetical actions.
- Stem
- The base part of a verb that endings are added to.
- Irregular stem
- A verb base that does not follow the regular infinitive pattern in the future or conditional.
- Si clause
- A clause beginning with si that states a condition for another action.
- Imperfect endings
- The endings -ais, -ais, -ait, -ions, -iez, and -aient used to form the conditional with a future stem.
Common Mistakes to Avoid
- Using the conditional ending with a present stem, such as je finissais for I would finish, is wrong because the conditional needs the future stem: je finirais.
- Forgetting to drop the final e from -re verbs in the future, such as je vendreai, is wrong because the correct form is je vendrai.
- Using the future tense after si in the same clause, such as si j'aurai le temps, is wrong because si + present is used for real future conditions: si j'ai le temps.
- Mixing future and conditional meanings is wrong because je parlerai means I will speak, while je parlerais means I would speak.
- Using regular stems for irregular verbs, such as je êtreai or je allerais, is wrong because être uses ser- and aller uses ir-: je serai and j'irais.

Understanding Future Simple & Conditional Reference
The choice between these forms is not only about time. It shows how certain or imagined the speaker feels. Use the future when an event is presented as expected, promised, predicted, or planned from the speaker's current point of view.
French often uses the present tense for a near or fixed plan, especially with a time word. Je pars demain can mean I am leaving tomorrow. The future gives more emphasis to the later result.
It is common in weather reports, instructions, warnings, and formal announcements. Words such as demain, bientôt, plus tard, quand, and dès que often help signal that a future idea is coming.
Spelling matters because the future stem stays visible inside a longer verb form. With verbs ending in re, the missing final e prevents an awkward spelling pattern. Irregular stems need to be learned as whole building blocks, not guessed from the present tense.
A student may know that je suis comes from être, yet the future stem is ser. This is why a small personal list of frequent irregular verbs is useful. Pronunciation creates another challenge.
Several singular future forms sound alike in normal speech. The written ending still tells the reader who performs the action. Pay close attention to the forms for nous and vous because their endings are easier to hear and often reveal the tense clearly.
The conditional lets a speaker create distance from a statement. That distance can show politeness, uncertainty, a wish, advice, or an imagined result. In a shop, Je voudrais un billet sounds less direct than a demand.
In advice, Tu pourrais parler au professeur means you could speak to the teacher. The conditional has another important use in stories and reported speech. Je pensais qu'elle viendrait means I thought that she would come.
The coming was future from the earlier moment of thinking, even if the event may now be over. This use appears often in novels, news reports, and classroom reading passages.
Si clauses follow a logic that English speakers must watch carefully. After si meaning if, French does not normally place the future tense directly in that clause. The tense after si shows the type of condition.
A present tense condition feels open or realistic. An imperfect condition describes an imagined, less likely, or unreal situation in the present. Si j'avais plus de temps, je voyagerais means that I do not have enough time now.
For an unreal past situation, French can use si plus the pluperfect with the past conditional. Practice these patterns as complete sentence pairs. First identify the condition.
Then identify its result. This prevents the common mistake of choosing a tense from an English word-for-word translation.
