Functional Grammar for DELF B2: A Practical Tutorial
Let’s be clear from the start: in the DELF B2 exam, grammar is not about perfection. It is about function. Grammar is the tool that allows you to express nuance, structure your reasoning, and build convincing arguments in French. Many candidates focus on avoiding mistakes or inserting sophisticated forms to “sound advanced.” This often leads to stiff, unnatural writing. What examiners actually reward is your ability to use grammar to think in French: to justify a position, acknowledge opposing views, hypothesize consequences, or frame a request politely.
In this tutorial, you will learn:
how each tense functions inside an argument
which grammatical forms signal nuance and sophistication
how genre (essay vs. formal letter) changes tense choice
how to build paragraphs with PDC
when to use subjonctif, conditionnel, and past tenses
What is Functional Grammar?
This guide is not a traditional grammar lesson. It is a strategy guide. We will explore how grammar operates inside real DELF B2 tasks—how each tense and structure has a specific communicative purpose. You will see how grammar supports the rhetorical moves of a strong essay or a formal letter, and how your grammatical choices signal maturity, clarity, and control.
Before memorizing rules, ask yourself three questions every time you write:
What am I trying to do? (persuade? concede? hypothesize?)
How do I show that grammatically?
Which form best expresses this function?
Although the word “grammar” does not appear as a separate category in the DELF B2 rubric, it is assessed in two major areas: Compétence linguistique and Compétence pragmatique. These refer to your mastery of grammatical structures and vocabulary, but also to your ability to use them to organize discourse, maintain coherence, and construct a relevant argument. Grammar is not evaluated in isolation; it is evaluated in context—as the engine that drives your ideas.
1. Compétence linguistique
Under compétence linguistique, examiners look at how well you control the grammatical structures you choose to use. They are not checking whether you know the names of tenses, or whether you can produce complex verb endings on command; instead, they want to see that the forms you use are appropriate, accurate, and flexible enough to support your ideas. This includes grammatical range—whether you can move beyond repetitive sentence frames—but also morphosyntactic accuracy: how reliably you form relative clauses, use agreement, or manage tense relationships.
A candidate who writes clearly, with controlled verbs and stable sentence patterns, demonstrates linguistic competence even if the text contains a few minor errors. The real question behind this criterion is simple: Are you using grammar in a way that supports your meaning?
This includes:
maîtrise des structures grammaticales (control of grammatical structures)
précision lexicale (lexical accuracy / richness)
correction morphosyntaxique (morphology + syntax accuracy)
In other words:
Are you using the right grammatical forms accurately
2. Compétence pragmatique
The second area, compétence pragmatique, is where the functional dimension of grammar becomes essential. Here, examiners look not only at the correctness of your language, but at how effectively you use that language to organise your discourse, connect ideas, and fulfill the communicative purpose of the task. This includes:
organisation du discours
cohérence
cohésion
pertinence de l’argumentation
adaptation au genre (lettre, essai, etc.)
Here, grammar is not a form, but a tool.
Example:
Conditional → hypothesis
Subjonctif → concession, uncertainty
Passive → depersonalization, formal tone
Relative clauses → introduce information elegantly
The rubric is essentially asking:
Does your grammar help you do the communicative job required by the task?
Understanding The Question: Letter vs. Formal Essay
For the DELF B2 Production Écrite, the two possible genres are almost always:
Un essai (argumentatif) – An argumentative essay for a school magazine, a forum, or a general publication.
Une lettre formelle – A formal letter (e.g., of complaint, application, request to an authority).
What you will NOT typically be asked to write at DELF B2:
A personal blog post (like a diary entry).
A fictional narrative.
A true, objective news article (like in a newspaper).
Why the confusion? The prompt might frame the essay as a “contribution to a blog.” However, the text you are required to produce is still a structured, argumentative essay. The “blog” is just the context to make the task more realistic. The grading criteria (coherence, cohesion, argumentation, language range) remain those of a formal essay.
Example of a misleading prompt:
“Le site internet de votre ville a créé un blog sur la vie citoyenne. Vous décidez d’y écrire un article pour donner votre opinion sur ce projet : ‘Faut-il rendre les transports en commun totalement gratuits ?'”
(The internet site of your city has created a blog on civic life. You decide to write an article to give your opinion on this project: ‘Should public transport be made completely free?’)
Despite the “blog” context, you must write a formal essai argumentatif.
Core Principle for B2 Writing
The key thing to remember is that you do not have to use all the tenses you have learnt. What is expected is that You should demonstrate the ability to use the core B2 tense system when it is appropriate for the communicative function: Présent, Passé Composé, Imparfait, Futur Simple, Conditionnel Présent, and the Subjonctif. The key is using them strategically to achieve your communicative goal.
Genre 1: The Argumentative Essay (Essai Argumentatif)
Move 1: Introduction – Presenting the Issue
Tenses: Présent is dominant.
Functional Reason: The present tense is used to state universal truths, general facts, and the current state of the debate. It frames the topic as a timeless, ongoing issue.
Example:
De nos jours, **il est fréquent de** (Présent) voir des débats sur...(General truth)Cet essai **a pour but d'** (Présent) examiner...(Stating the purpose now)Nous **verrons** (Futur Simple) tout d'abord... puis nous **analyserons** (Futur Simple)...(Outlining the structure for the reader).
Move 2: Body Paragraphs – Developing Arguments (PDC Structure)
P – Présentation (Topic Sentence):
Tense: Présent.
Reason: States the main argument as a general claim.
Un premier avantage **est** (Présent) la flexibilité.
D – Développement (Supporting Ideas):
Tenses: Présent, Passé Composé/Imparfait, Conditionnel.
Functional Reasons:
Présent: For general explanations and facts. (
Cela **permet** aux employés de...)Passé Composé/Imparfait: To provide a concrete example from a past event or a known study. This is a powerful B2 technique.
**On
a vu** (Passé Composé) lors de la pandémie que le télétravail **a
permis** (Passé Composé) de maintenir l'activité économique.Une étude récente **a démontré** (Passé Composé) que...
Conditionnel Présent: To hypothesize or suggest a potential consequence. This shows nuance.
Si cette tendance se poursuivait, elle **entraînerait** (Conditionnel) des changements profonds.
C – Conclusion Partielle (Mini-Consequence):
Tenses: Présent, Futur Simple.
Reason: To draw a general conclusion from the argument just made or to project a future consequence.
Il **est** donc clair que (Présent) cette solution **est** (Présent) bénéfique.Si cette mesure **est** (Présent) adoptée, elle **permettra** (Futur Simple) de résoudre le problème.
Move 3: Conclusion – Synthesizing and Offering Perspective
Tenses: Présent, Conditionnel, Subjonctif (in set phrases).
Functional Reasons:
Présent: To state your final, balanced opinion. (
En conclusion, je **pense** que...)Conditionnel: To make a polite recommendation or suggest a prudent course of action. This is more nuanced than the Futur Simple.
Il **serait** donc judicieux de...(It would be wise to…)Les pouvoirs publics **devraient** envisager de...(The authorities should consider…)
Subjonctif: Used in classic concluding phrases after
il faut queoril est essentiel que.Il **faut** donc **que** le gouvernement **agisse** (Subjonctif).
Futur Simple / Conditionnel: For an “ouverture” (opening) that looks to the future.
À l'avenir, il **conviendra** (Futur Simple) d'étudier l'impact à long terme.On **pourrait** (Conditionnel) également se demander si...
Genre 2: The Formal Letter (Lettre Formelle)
This genre has a more narrative and prospective structure, tied to its purpose (complaint, application, request).
Move 1: Exposition des Faits (Stating the Facts)
Tenses: Passé Composé, Imparfait.
Functional Reason: You are narrating a past event that prompted you to write the letter (e.g., a problem you encountered, a product you bought, an article you read).
Example (Complaint):
Je me **permets** (Présent) de vous écrire au sujet de l'incident qui **a eu lieu** (Passé Composé) le 15 mai dernier.Je **vous ai envoyé** (Passé Composé) un colis le... mais il **est arrivé** (Passé Composé) endommagé.
Move 2: Explication / Argumentation (Explaining the Problem/Your Position)
Tenses: Présent, Passé Composé.
Reason: You explain the current consequences of the past event or state your current qualifications (in a job application).
Cette situation **a pour conséquence** (Présent) de...Actuellement, je **suis** (Présent) employé chez... et je **possède** (Présent) une solide expérience en...
Move 3: Demande / Proposition (The Request or Proposal)
Tenses: Conditionnel Présent, Futur Simple.
Functional Reason: This is the core of the letter. The Conditionnel is the polite and standard tense for making formal requests. The Futur Simple can be used to state what you will do.
C'est pourquoi je **voudrais** (Conditionnel) vous demander un remboursement.**Serait-il** (Conditionnel) possible de recevoir une compensation ?Dans l'attente de votre réponse, je vous **prie** (Présent) d'agréer, Madame, Monsieur, mes salutations distinguées.(Set phrase in Present).
Move 4: Menace / Conséquence (Implied or Stated Consequence – optional)
Tenses: Futur Simple, Conditionnel Passé.
Reason: To state what will happen if your request is not met. Use this carefully and politely.
Si aucune solution n'**est** (Subjonctif) trouvée, je me **verrai contraint de** (Futur Simple) saisir les autorités compétentes.Sans réponse de votre part, j'**aurais été** (Conditionnel Passé) obligé d'entreprendre des démarches légales.(Very formal).
The Imparfait in DELF B2
The Imparfait is less frequent in DELF B2 writing than the Présent, Passé Composé, Futur, and Conditionnel. Here’s the functional reason why:
The B2 written tasks are primarily focused on argumentation, persuasion, and future-oriented proposals.
The Imparfait is the tense of description, habit, and ongoing background actions in the past. Its functions are less central to the core goals of the B2 writing tasks.
However, a strong B2 candidate can and should use it strategically in specific moves:
Strategic Uses of the Imparfait in DELF B2 Writing:
1. In the Lettre Formelle: Narrating the Problem
This is its primary location. You use the Imparfait to set the scene and describe the ongoing situation when your problem occurred (using the Passé Composé).
Move: Exposition des Faits
Je vous écoute au sujet du vol **que j'ai subi** (Passé Composé - the main event) le 15 mai. Ce jour-là, **il faisait** (Imparfait - setting the scene) nuit et **il y avait** (Imparfait) peu de monde dans la rue.**J'étais** (Imparfait - describing your state) client de votre magasin depuis plusieurs années et **j'effectuais** (Imparfait - a habitual action) tous mes achats chez vous.
2. In the Essai: Providing Context or a Historical Example
You can use it to contrast a past situation with the present one.
Move: Introduction / Body Paragraph
**Autrefois, l'université était** (Imparfait) un privilège. **Aujourd'hui, elle est** (Présent) considérée comme un droit.(Contrasting past and present).Pour illustrer ce danger, on peut rappeler que pendant la guerre froide, la propagande **était** (Imparfait) un outil essentiel pour les deux camps.(Describing a past context for a current argument).
3. In the Essai: Explaining a Past Habit or General Truth
Les études **montraient** (Imparfait - a general truth held in the past) que... mais de nouvelles données **ont prouvé** (Passé Composé - a recent discovery that changes things) que...
Summary Table: Tense Function by Purpose
| Move Step | Primary Genre | Key Tenses | Functional Purpose |
|---|---|---|---|
| Introduce Topic | Essay & Letter | Présent, Futur Simple | State general truths, outline structure |
| Narrate Facts | Letter | Passé Composé, Imparfait | Tell the story that led to the letter |
| State Argument | Essay | Présent | Present a general claim |
| Give Examples | Essay | Passé Composé | Provide concrete, past evidence |
| Hypothesize | Essay | Conditionnel Présent | Suggest possible consequences or outcomes |
| Make a Request | Letter | Conditionnel Présent | Polite, formal requests |
| Draw Conclusion | Essay | Présent, Conditionnel | State final opinion, make recommendations |
| Look to Future | Both | Futur Simple, Conditionnel | For an “ouverture” or future action |
Final Pro DELF B2 -Tip: The most common mistake at B2 is using only the Present tense. To score highly, you must orchestrate your tenses. Weave in a past tense example to ground your argument, use the Conditional to show nuance, and employ the Future Simple to project consequences. This functional use of grammar is what examiners reward.
