Read an obligation without confusing it with a fact
Devoir followed by an infinitive can express an obligation or necessity. « Je dois lire ce texte » means I have to, or must, read this text in the relevant context. It does not report that I have already read it. A sentence about what is required and a sentence about what happened provide different information.
The present forms are je dois, tu dois, il doit, elle doit, nous devons, vous devez, ils doivent and elles doivent. The following verb remains an infinitive: « Vous devez parler », not « Vous devez parlez ». In these patterns the conjugated modal carries person and number; the infinitive names the required action.
Negation changes the demand: « Tu ne dois pas jouer ici » normally tells the addressee not to play here. It is not a helpful translation of “you do not have to play here”, which removes an obligation rather than forbidding an action. Think about meaning before choosing an English equivalent.
Devoir has additional context-dependent uses, including expectations and deductions. This introductory note concentrates on clearly stated duties in original practice situations. It does not turn a speaker’s obligation statement into a platform rule or a moral judgement about the reader. A useful response identifies who is expected to do what and whether the sentence asserts that it occurred.
An obligation and its fulfilment are different propositions. In « Je dois préparer le texte aujourd’hui, mais je veux aller au parc », the speaker has a stated duty and a contrasting wish. Neither proves that the text is ready. Compare « Tu ne dois pas laisser tes déchets dans le parc »: in this rule-like context it is a prohibition, not reassurance that leaving rubbish is optional. Devoir can carry other meanings in other contexts, including inference, so the lesson supplies a clear duty or rule before choosing must. Identify who states the obligation and which infinitive it concerns instead of converting every occurrence mechanically into an accomplished action.
Transfer task: tell a group that they must prepare the images and must not leave rubbish in the park. A model is « Vous devez préparer les images et vous ne devez pas laisser vos déchets dans le parc. » Devez agrees with vous in both clauses; préparer and laisser remain infinitives. Vos replaces tes because the addressee changes. A reasoned answer distinguishes the positive duty from the negative prohibition and explains why neither sentence reports successful completion. Do not translate the negative as you do not have to leave rubbish: that would remove the intended restriction. The task practises a supplied rule, not a universal claim about actual local laws or festival regulations.
Worked example: Write “You must read the text” addressing several people, using devoir and lire.
Use vous devez for the plural addressees.
Keep lire as the infinitive.
Add le texte as the direct object.
Answer: Vous devez lire le texte.
Check your understanding: Does « Elle doit lire » establish that she has finished reading?
Answer: No. It states a duty or necessity in context; it does not report a completed reading event.
Why: The present modal plus infinitive differs from a perfect-tense event report.
