Metonymy or synecdoche in French: identify the relationship
Distinguish French metonymy from synecdoche through association and part–whole links. Interpret examples, compare literal readings and justify your answers.
In short
Ask how the named thing relates to the intended thing. Lire Balzac uses an author for his works: association, or metonymy. Trois voiles à l’horizon can use a part for sailing boats: synecdoche. State the relationship in words before choosing the label.

Association or inclusion?
La salle a applaudi.The room applauded.
Focus: Metonymy: a place stands for the people occupying it.
place → occupants
La salle a applaudi les musiciens.
The audience in the room applauded the musicians.
Trois voiles approchaient du port.Three sails were approaching the harbour.
Focus: Synecdoche: a visible part stands for the sailing boat as a whole.
part → whole
Trois voiliers approchaient du port.
Three sailing boats were approaching the harbour.
Use the narrower contrast here: métonymie for an association such as author and work, synecdoque for inclusion such as part and whole. Some classifications place synecdoche within the wider family of metonymy. Naming the precise link keeps your interpretation clear across those classifications.
| French in context | Intended meaning | Relationship | Label here |
|---|---|---|---|
| Elle lit Balzac dans le train. | She reads works by Balzac. | Author → works | Metonymy |
| Il a bu un verre après le repas. | He drank the contents of a glass. | Container → contents | Metonymy |
| La mairie a répondu à notre lettre. | The municipal administration replied. | Place / institution name → people acting for it | Metonymy |
| Cette revue réunit de grandes plumes. | The review brings together fine writers. | Writing instrument → users | Metonymy |
| Trois voiles entraient dans le port. | Three sailing boats were coming in. | Physical part → whole vessel | Synecdoche |
| Il cherche un toit pour la nuit. | He is looking for somewhere to stay. | Part of a dwelling → shelter as a whole | Synecdoche |
| Le troupeau compte vingt têtes. | The herd has twenty animals. | Body part → whole animal | Synecdoche |
The same word can be literal
Le vent a déchiré trois voiles. Le bateau doit rester au port.
The wind tore three sails. The boat has to stay in the harbour.
Here the sails themselves are damaged. The sentence gives no reason to replace them with whole boats.
Trois voiles se détachaient sur l’horizon. Une heure plus tard, les bateaux entraient au port.
Three sails stood out against the horizon. An hour later, the boats were entering the harbour.
The following sentence supports the part-for-whole reading. The observer first notices the sails.
Likewise, elle a lavé le verre usually concerns the glass itself, while elle a bu un verre concerns its contents. The verb helps select the reading. Identify the intended referent from the whole sentence and its neighbours; a noun alone rarely settles the figure.

Dans « trois voiles », une partie visible désigne les bateaux entiers. Cette synecdoque adopte le regard d’un observateur qui distingue d’abord les voiles au loin.
In “three sails”, a visible part designates the whole boats. This synecdoche adopts the gaze of an observer who first makes out the distant sails.
Dans « de grandes plumes », l’instrument désigne les écrivains. Cette métonymie les présente à travers leur activité et valorise ici leur talent.
In “fine pens”, the instrument designates the writers. This metonymy presents them through their activity and here praises their talent.
A quill is an instrument used by a writer, so the link is association rather than a physical part of the writer. That is why de grandes plumes goes in the metonymy column here. Compare vingt têtes for twenty animals: the head is a physical part of each animal.
What is the difference between metonymy, synecdoche and metaphor?
Au travail, Paul est un renard : il trouve toujours le moyen d’éviter les pièges.
At work, Paul is a fox: he always finds a way to avoid traps.
This image rests on a perceived resemblance in cleverness. That makes it a metaphor, rather than an association or a part–whole substitution.
