Key grammar topics to master for DELF B1–B2
To succeed at the DELF B1 and B2 levels, it is essential to master a range of intermediate and advanced grammar topics that enable clear, nuanced communication in both written and spoken French. 1, 4, 5
At B1, the main goal is to build control over the basic narrative and opinion structures needed to handle everyday topics with increasing independence. At B2, the expectation rises: grammar should support precision, argumentation, and flexibility, especially when speaking about abstract ideas, comparing viewpoints, and justifying a position.
Essential Grammar Topics for B1–B2
-
Use and distinction of past and future tenses (passé composé, imparfait, plus-que-parfait, futur simple) to tell stories, describe habits, and make plans. 4, 7
The passé composé typically presents completed events, while the imparfait describes background, repeated actions, states, or ongoing situations. The plus-que-parfait adds an earlier layer in the past, which is useful for explaining what had already happened before another event. The futur simple is the standard form for predictions, promises, and plans that are not yet realized.
A B1 speaker should be able to say: Quand j’étais enfant, je jouais souvent dans ce parc, mais un jour j’ai rencontré un chien qui m’a fait peur. At B2, the same story becomes more precise: Je me suis rendu compte que j’avais oublié mes clés, donc je suis rentré plus tôt que prévu.
-
Introduction and mastery of the subjunctive mood, both present and past, to express wishes, emotions, uncertainty, or necessity. 5, 1
The subjunctive is one of the clearest dividing lines between elementary and intermediate French. It appears after structures such as il faut que, je veux que, bien que, pour que, and avant que. In spoken French, it is common in formal and semi-formal conversation, and it often signals control over more than just memorized phrases.
The present subjunctive is used for current or general situations: Je veux qu’il vienne. The past subjunctive is less frequent in everyday speech but remains relevant in reading and more formal writing: Je suis content qu’elle soit partie avant la pluie.
-
Conditional mood and conditional sentences, including how to express hypothetical or polite statements. 4, 5
The conditional is essential for polite requests, softening opinions, and discussing unreal situations. It is also the core of many common exam answers because it allows a learner to speculate without sounding absolute.
Typical uses include: Je voudrais, J’aimerais, Pourriez-vous… ? for politeness, and Si j’avais plus de temps, je voyagerais davantage for hypothetical situations. A common B2-level skill is combining conditional with more complex clauses: Si la ville investissait davantage dans les transports, les habitants gagneraient du temps et respireraient un air moins pollué.
-
Pronoun usage, including direct/indirect object pronouns, relative pronouns (qui, que, où, lequel, dont) for linking ideas and avoiding repetition. 1, 5, 4
Pronouns are a major marker of fluency because they reduce repetition and make sentences more natural. French exam tasks often reward the ability to chain ideas cleanly instead of repeating nouns.
Direct and indirect object pronouns must be placed in the correct order, which is a frequent source of mistakes: Je le lui ai donné is correct, while Je lui le ai donné is not. Relative pronouns also matter because they let speakers build longer, more connected sentences: Le film que j’ai vu hier, la personne à qui j’ai parlé, la ville où j’habite, le livre dont je me souviens.
-
Complex sentence structures, using conjunctions and logical connectors (parce que, pourtant, donc, tandis que) to articulate cause, contrast, result, or opposition. 7, 1, 4
B1 learners often rely on simple coordination with et and mais. B2 requires a wider range of logical links, including nuance between cause, consequence, concession, and opposition. Connectors such as cependant, néanmoins, en revanche, par conséquent, alors que, and même si help organize ideas clearly in both essays and oral responses.
A strong answer does not only state an opinion; it shows the relationship between ideas: Je comprends cet argument, pourtant je pense que la solution est insuffisante. This kind of structure is especially useful in discussions of society, work, education, and technology.
-
Mastery of compound relative pronouns and demonstrative pronouns (celui, celle, ceux, celles), and when to use them. 5, 1
Demonstrative pronouns help identify one item among several and are especially useful when comparison or contrast is involved. They often appear with -ci and -là to distinguish between nearby and more distant references: Je préfère celle-ci, Ceux-là sont plus chers.
Compound forms such as celui qui, celle que, ceux dont are especially useful in French because they avoid repetition while keeping the sentence precise: Je prends celui qui est plus rapide, Elle choisit celle qu’elle connaît déjà.
-
Use of verbal prepositions, including those governing different verbs (réussir à, penser de/à, etc.). 1
Verb-preposition pairs are a recurring obstacle because French often requires a specific preposition where another language would not. At B1–B2, the expected range includes expressions such as réussir à, penser à, penser de, s’habituer à, avoir besoin de, se rendre compte de.
These combinations should be learned as fixed units rather than translated word for word. A small preposition error can change meaning or sound unnatural, especially in spoken answers where accuracy and speed both matter.
-
Reported (indirect) speech for relaying messages, questions, or instructions. 5
Indirect speech allows a speaker to summarize what someone said instead of quoting it exactly. It is useful in narration, news-style reporting, and conversation. Common shifts include tense changes and changes in pronouns or time expressions: Il a dit qu’il viendrait demain becomes Il a dit qu’il viendrait le lendemain in a later context.
Questions also change form: Il m’a demandé où j’allais rather than a direct question. This structure is important in both reading comprehension and oral retelling tasks.
-
Passive voice and agreement of the past participle in various tenses. 7, 5
The passive voice appears less often than the active voice, but it is important for formal writing, descriptions of processes, and emphasis on the receiver of an action: Le rapport a été publié hier. At B2, learners should also recognize when the passive sounds more natural than the active in French, especially in institutional or academic contexts.
Past participle agreement is another frequent exam point because it affects standard written accuracy. With être, agreement is automatic in compound tenses: elle est arrivée. With avoir, agreement depends on whether the direct object comes before the verb: les lettres qu’elle a écrites.
-
Expansion of idiomatic expressions and precise use of adverbs (time, manner, frequency, place) to enrich meaning. 4, 1
Idiomatic expressions help speech sound more natural and less textbook-like. Common adverbs such as souvent, rarement, déjà, encore, ailleurs, partout, lentement, and heureusement refine meaning and improve sentence rhythm.
At B2, precision matters: un peu and assez do not communicate the same degree, and depuis, pendant, and pour are not interchangeable. Using the right adverb or idiom can make a response more convincing without making it longer.
Application Across Skills
-
The ability to build more sophisticated sentences for explaining opinions and complex situations, essential for both written production and oral exams. 1, 4
In written tasks, this means producing cohesive paragraphs with a clear line of reasoning. In speaking tasks, it means going beyond short answers and being able to explain a situation, give an example, and qualify a statement. A response such as Je suis plutôt d’accord, mais seulement si les conditions sont réunies is already much closer to B2-style control than a simple oui or non.
Active conversation practice helps here because grammar at this level is not only about recognition; it is about retrieving forms quickly under pressure.
-
Knowledge of these grammar topics allows for comprehension and contribution in discussions, debates, and speculation on various subjects. 5, 1
The B2 level especially rewards flexibility. A learner who can speculate with the conditional, soften claims with modal expressions, link ideas with connectors, and switch between past perspectives can take part more naturally in conversations about news, work, travel, health, or culture.
In reading and listening, the same grammar structures signal meaning at speed. Recognizing a subjunctive clause, a passive construction, or a chain of relative pronouns often makes the difference between partial understanding and confident comprehension.
Common pitfalls at B1–B2
- Mixing up passé composé and imparfait in narratives, especially when describing background versus completed actions.
- Using the subjunctive only in isolated memorized phrases instead of after the full range of triggers.
- Overusing et and mais instead of more precise connectors such as donc, cependant, or par conséquent.
- Forgetting pronoun placement in compound tenses.
- Choosing the wrong preposition after a verb, particularly with high-frequency expressions.
- Translating directly from another language when French requires a different structure.
At DELF B1, these mistakes can reduce clarity. At B2, they also affect the impression of control, which matters in both written production and oral interaction.
Mastering these grammar structures and practicing their use in context is critical for success on the DELF B1 and B2 exams. 4, 1, 5
What matters most in practice?
The most useful grammar for DELF B1–B2 is the grammar that helps manage real communication: narrating events, explaining reasons, expressing uncertainty, comparing ideas, and responding politely. That is why tense control, pronouns, connectors, and the subjunctive sit at the center of exam preparation.
A learner who can combine these structures naturally is much better equipped for the longer speaking turns and more complex writing tasks expected at B2.
