Dont Spanning a Longer Embedded Structure

Level 5

In formal French, the relative pronoun dont can reach across a 'bridge' verb (like savoir or penser) to replace a noun or adjective that requires the preposition de inside a nested clause.

How It Works

This structure, often called a relative génitive longue, is a hallmark of high-level formal writing.

1. Syntactic Logic
The pronoun dont replaces a phrase starting with de. In complex embedding, that de-phrase is buried inside a second clause (usually introduced by que).
Example: C'est une situation dont je pense que l'issue sera favorable.
Deep structure: Je pense que l'issue de cette situation sera favorable.

2. Usage and Register

  • Register: Highly formal (literary, legal, or academic).
  • Function: It avoids the 'floating' que or the need for redundant possessive adjectives (like son/sa) or the pronoun en.
  • Bridge Verbs: It typically follows verbs of thought or speech like savoir, penser, imaginer, craindre, or dire.

3. Key Rule: No Redundancy
When using dont in this way, you must not use a possessive adjective or the pronoun en for the same relationship. Dont already performs that function.

  1. C'est une affaire dont je crains que le dénouement ne soit tragique.

    It is a matter of which I fear the outcome will be tragic.

    Word by Word: It is an affair of-which I fear that the outcome [ne] be tragic.

    Here, 'dont' replaces 'de cette affaire'. The logic is: 'Je crains que le dénouement de cette affaire ne soit tragique.'

  2. Un luxe dont j'imagine aujourd'hui qu'il devait être affreux.

    A luxury of which I imagine today that it must have been awful.

    Word by Word: A luxury of-which I imagine today that it must-have to-be awful.

    A classic example from Proust. 'Dont' sets the topic ('regarding this luxury') for the following nested clause.

  3. L'homme dont je sais que le fils est souffrant est arrivé.

    The man whose son I know is unwell has arrived.

    Word by Word: The man of-whom I know that the son is suffering is arrived.

    In formal French, 'dont' replaces the need for 'son fils'. The logic is: 'Je sais que le fils de cet homme est souffrant.'

  4. C'est un projet dont je pense que vous avez besoin pour réussir.

    It is a project that I think you need in order to succeed.

    Word by Word: It is a project of-which I think that you have need for to-succeed.

    Since the verb is 'avoir besoin de', 'dont' is used to link the project to the nested 'que' clause.

Common Mistakes

  • Using a possessive adjective (son/sa/ses) alongside 'dont'.

    L'homme dont je sais que son fils est malade.
    L'homme dont je sais que le fils est malade.

    Because 'dont' already expresses the possessive relationship ('of whom'), using 'son' is redundant (a pleonasm).

  • Using 'que' when the nested verb requires 'de'.

    Le livre que je pense que tu as besoin.
    Le livre dont je pense que tu as besoin.

    The expression is 'avoir besoin de'. Therefore, the relative pronoun must be 'dont', even if it is separated from the verb by another clause.

Learn This First

To learn 'dont' in complex embedded clauses, you must first be comfortable with the basic relative pronoun 'dont' and how it replaces 'de' phrases. You also need a strong grasp of how French relative clauses can nest within one another, particularly when 'dont' acts as a possessive or a complement to a noun deep inside the structure.
