The Grammatical Structure: How Is It Used?

The structure of the verb "obbligare a" is quite clear and appears mainly in two forms:

• Basic formula with the infinitive:
  • [Subject] + obbligare (conjugated) + [Direct Object (optional)] + a + [Infinitive]
  • Example: "Loro mi hanno obbligato a restare oltre l'orario di chiusura."
• Use with Nouns/Pronouns (when the obligation is towards something):
  • [Subject] + obbligare (conjugated) + a + [Noun/Pronoun]
  • Example: "Le regole cittadine ci obbligano al rispetto dell'ambiente."

The preposition "a" is essential when "obbligare" is followed by an action expressed with an infinitive or by a noun indicating the object of the obligation. It indicates the direction or purpose of the compulsion, linking the person under obligation to the action or duty imposed. Without "a" in these contexts, the sentence would be grammatically incorrect or the meaning would be altered. The verb "obbligare" is typically transitive (it takes a direct object, as in "obbligare qualcuno"), but its use with "a" is standard to introduce the obligatory action.

Crucial Differences: Common Mistakes to Avoid

Understanding the subtle differences and correct usage is essential to avoid common mistakes when using "obbligare a".

• "Obbligare a" + Infinitive vs. "Obbligare DI/PER" + Infinitive

  • "Obbligare a" + Infinitive: This is the correct and widely used construction in contemporary Italian to express a compulsion or imposition. The preposition "a" is the standard and most natural form.

    • Example: "La legge lo obbliga a pagare le tasse ogni anno." (Correct and common)

  • "Obbligare DI/PER" + Infinitive: Although in the past (especially in older literary texts) they were in some cases accepted, the constructions "obbligare di" or "obbligare per" followed by an infinitive are today considered obsolete or grammatically incorrect in modern spoken Italian. The use of "di" or "per" in these contexts sounds unnatural and should be avoided.

    • Example: "Mi hanno obbligato di restare." (Incorrect/Archaic)
    • Example: "Li ho obbligati per venire." (Incorrect) To learn more about the usage of the verb "obbligare" and its possible constructions, you can consult the full definition on Treccani.

• "Obbligare" vs. "Costringere"

  • "Obbligare": This verb often implies a moral, legal, contractual force, or an objective necessity that imposes an action. The compulsion may be less direct or physical and more related to a duty or a logical consequence.

    • Example: "Il contratto di lavoro lo obbliga a rispettare la clausola di riservatezza per due anni."

  • "Costringere": Emphasizes a more direct and immediate coercion, often with a connotation of physical force, psychological pressure, threat, or violence. The imposed action is often perceived as unpleasant or against the subject’s will.

    • Example: "I rapinatori lo hanno costretto a svuotare la cassaforte sotto la minaccia delle armi."
    • Example: "La forte tosse persistente mi ha costretto a rinunciare alla serata con gli amici."
