French Liaison Exceptions List: When NOT to Link Words

French Liaison Exceptions List: The Definitive Guide to Forbidden Liaisons

In the French language, few phonetic phenomenons are as celebrated—and as perplexing—as the liaison. This vocal bridge connects the silent final consonant of one word to the beginning vowel sound of the next, producing that smooth, uninterrupted musicality French is famous for.

However, fluency is not just about making connections; it is equally about knowing when to refrain. Making a liaison where none belongs (known in linguistics as a fausse liaison or pataquès) can sound jarring and immediately signals a non-native command of the language.

If you have been searching for a comprehensive French liaison exceptions list, this guide provides the authoritative breakdown of every major rule regarding forbidden liaisons (liaisons interdites).

1. Never After the Conjunction "Et" (And)

This is the single most rigid rule in French phonology: you must never, under any circumstances, make a liaison after the word et.

The conjunction et serves as a structural break between phrases or list items. Pronouncing a /t/ sound after it sounds profoundly unnatural to native speakers.

• Correct: Un homme et une femme -> pronounced `/œ̃ nɔm e yn fam/`
• Forbidden: Un homme et‿une femme (never say `/e.tyn/`)
• Correct: Lui et elle -> `/lɥi e ɛl/`

2. Before Words Starting with an "Aspirated H" (H aspiré)

In French, the letter H is never audibly pronounced. However, it exists in two grammatical categories that dramatically alter pronunciation:

1. Silent H (H muet): Behaves like a vowel. Liaison and elision are mandatory (les‿hommes -> `/le.zɔm/`, l'hôpital).

2. Aspirated H (H aspiré): Acts like an invisible consonant wall. It strictly blocks both elision and liaison.

Crucial Examples to Memorize:

• Les héros (the heroes) -> pronounced `/le e.ʁo/`.
• Warning: If you link them as `/le.ze.ʁo/`, native listeners will hear les zéros (the zeroes)!
• Les haricots (the beans) -> `/le a.ʁi.ko/`
• En haut (upstairs / at the top) -> `/ɑ̃ o/`
• Des hauteurs (heights) -> `/de o.tœʁ/`
• Les handicaps -> `/le ɑ̃.di.kap/`

> Pro Tip: When learning a new noun beginning with H, always check a French dictionary. A dagger or asterisk (e.g., `honte`, `hasard`) designates an aspirated H.

3. After a Singular Noun

A very common error among intermediate French students is carrying over the final consonant of a singular noun into the following adjective or verb. While plural nouns frequently link (des nuits‿entières), singular nouns never link.

• Singular Noun + Following Adjective:
• Un chat adorable -> pronounced `/œ̃ ʃa a.dɔ.ʁabl/` (do not pronounce the 't')
• Un soldat anglais -> pronounced `/œ̃ sɔl.da ɑ̃.glɛ/`
• Singular Subject Noun + Verb:
• Le président a voté -> pronounced `/lə pʁe.zi.dɑ̃ a vɔ.te/`
• Le train arrive -> pronounced `/lə tʁɛ̃ a.ʁiv/` (do not say `/tʁɛ̃.na.ʁiv/`)

4. After Proper Names

Proper nouns (people's names, company names, cities) retain their phonetic identity. You should never link the end of a proper name to the word that follows.

• Jean est en retard -> pronounced `/ʒɑ̃ ɛ ɑ̃ ʁə.taʁ/` (no /n/ link)
• Paris est magnifique -> pronounced `/pa.ʁi ɛ ma.ɲi.fik/` (the 's' stays completely silent)
• Lucas adore lire -> pronounced `/ly.ka a.dɔʁ liʁ/`

---

5. Before the Numbers "Huit" and "Onze"

Even though onze (eleven) starts with a vowel and huit (eight) starts with a silent letter combination, both numbers behave as if they start with a barrier consonant. They do not accept liaisons or contractions.

• Les huit chats -> pronounced `/le ɥi ʃa/` (NOT `/le.zɥi ʃa/`)
• Les onze joueurs -> pronounced `/le ɔ̃z ʒwœʁ/` (NOT `/le.zɔ̃z ʒwœʁ/`)
• Le premier de huit -> pronounced `/lə pʁə.mje də ɥit/`

• Les yaourts -> `/le ja.uʁt/`
• Les week-ends -> `/le wi.kɛnd/`

This same rule applies to loanwords beginning with a semi-vocalic "Y" or "W":

6. Inverted Questions (Verb-Subject Pronoun Inversion)

When a verb is inverted with a pronoun in formal questions, the liaison happens exclusively between the verb and that pronoun. You must never link that pronoun forward to an adjective, participle, or complement.

• Sont-ils arrivés ? -> The link occurs between sont and ils (`/sɔ̃.til/`), but never between ils and arrivés. Say `/sɔ̃.til a.ʁi.ve/`.
• Vont-elles ensemble ? -> Pronounced `/vɔ̃.tɛl ɑ̃.sɑ̃bl/`.

7. The Key Difference: Forbidden vs. Optional Liaisons

To master French phonetics, you must distinguish between two concepts:

1. Forbidden Liaisons (interdites): Violating these sounds incorrect and disrupts comprehension (covered above).

2. Optional Liaisons (facultatives): Linking after auxiliary verbs (Je suis‿allé), after plural nouns (des enfants‿heureux), or after prepositions (dans‿un instant). In casual modern spoken French, most optional liaisons are simply dropped. When in doubt, it is always safer to skip an optional liaison than to force a forbidden one.
