Complex subordination and embedding

Building a long, clear and hierarchical sentence.

⚡Key points

Main + subordinate clauses→relatives, completives, adverbials

Embedding→a clause inside a clause

Hierarchy of ideas→main vs secondary

Clarity: relative near its antecedent→avoid ambiguity

Période→a long balanced sentence

Types of subordinate clause

A complex sentence combines subordinate clauses of different types: relative (qui, que, dont), noun clauses (que + indicative/subjunctive), adverbial (time, cause, purpose…). Embedding is placing one clause inside another.

Levels of embedding

Relative within a noun clause

Je pense que le livre que tu m’as prêté est excellent.

Noun clause within an adverbial

Comme il savait qu’elle viendrait, il a préparé un repas.

Cascade

L’homme qui m’a dit qu’il partirait quand il aurait fini est revenu.

Clarity and hierarchy

The more levels, the higher the risk of ambiguity. Clarity rules: put the relative next to its antecedent; don’t pile up que… que… que; distribute ideas by hierarchy (the main idea in the main clause, secondary ones in subordinate clauses). Alternate subordination and coordination.

Problem → fix

Relative far from antecedent	ambiguous	place it next to it
Cascade of que… que	heavy	split / nominalise
Main idea in a subordinate	unclear hierarchy	put it in the main clause
Too long	the thread is lost	split into 2 sentences
Parallelism	rhythm and clarity	symmetrical structures

💡⚠️ Complexity in the service of clarity

The aim of a complex sentence is not to confuse but to express relations precisely between ideas. A good “période” is hierarchical and balanced. If a sentence becomes unclear, it is better to split it or to use nominalisation.

Heavy: Je crois que l’idée que tu as eue que nous partions est bonne.

Clear: Ton idée de partir me paraît bonne.

Dialogue: editing a long sentence

ProfTa phrase a quatre « que » de suite : illisible.

ÉlèveJe hiérarchise : l’idée principale dans la principale ?

ProfOui, et mets la relative près de son antécédent.

ÉlèveSinon, je coupe en deux phrases plus claires.

Teacher: Your sentence has four “que” in a row: unreadable. | Student: I’ll set the hierarchy: the main idea in the main clause? | Teacher: Yes, and put the relative next to its antecedent. | Student: Otherwise, I’ll split it into two clearer sentences.
