The Hiatus in French
Avoiding Hiatus in French
General Principle
French generally seeks to avoid the meeting of two consecutive vowel sounds. This phenomenon is called a hiatus.
To make pronunciation smoother and more fluid, French uses several mechanisms:
- elision;
- liaison;
- special forms of determiners;
- the appearance of semivowels (glides);
- certain spelling changes.
The goal is always the same:
to facilitate the transition between sounds and avoid a clash between two vowels.

1. Elision
Definition
Elision consists of dropping a final vowel before a word beginning with a vowel or a silent H.
Examples
Full Form Actual Form je aime j’aime je habite j’habite le ami l’ami la école l’école ce est c’est ne est pas n’est pas de accord d’accord que elle qu’elle
Words That Commonly Undergo Elision
- je → j’
- le → l’
- la → l’
- ce → c’
- ne → n’
- de → d’
- que → qu’
2. Silent H and Aspirated H
Silent H (H muet)
The H is not pronounced and does not block elision.
Therefore, elision takes place.
Examples
- l’homme
- l’hôtel
- l’habitude
- j’habite
- l’histoire
Aspirated H (H aspiré)
The H is still not pronounced, but it blocks elision and liaison.
Examples
- le héros
- le haricot
- la honte
- le hasard
- le hibou
We say:
✅ le héros
❌ l’héros
3. Possessive Adjectives Before a Vowel
To avoid hiatus, feminine possessive adjectives change form before a vowel.
Before a Consonant Before a Vowel ma sœur mon amie ma voiture mon auto ta sœur ton amie sa sœur son ancienne collègue The noun remains feminine.
The change exists solely to facilitate pronunciation.
4. Demonstrative Adjectives
Before a Consonant Before a Vowel ce livre cet arbre ce garçon cet étudiant ce musée cet hôtel The form cet prevents the awkward sequence between ce and a following vowel.
5. The Contraction “s’il”
French avoids:
❌ si il
and instead uses:
✅ s’il
Examples:
- s’il vient
- s’il pleut
- s’ils arrivent
6. Liaison
Liaison creates an intermediate sound between two words.
Examples
Spelling Pronunciation les amis lay-zah-mee un ami un-nah-mee nous avons noo-zavon ils arrivent eel-zariv The liaison consonant acts as a bridge between two vowel sounds.
7. Semivowels (Glides)
French often transforms a vowel into a semivowel.
The Three Main French Semivowels
Symbol Example [j] bien, pied, voyons [w] oui, moi, loi [ɥ] lui, nuit, huit These sounds help avoid or soften hiatus.
8. The Case of “voir”: nous voyons
Why do we write “voyons”?
One could theoretically imagine:
- voi + ons
The succession of vowels would be less natural.
French instead introduces the semivowel [j], represented by the letter y.
This produces:
- nous voyons
- vous voyez
Pronunciation:
- vo-yons
- vo-yez
The letter Y functions as a transition between vowels.
9. Other Similar Verbs
Infinitive Conjugated Form voir nous voyons envoyer nous envoyons nettoyer nous nettoyons employer nous employons In all these cases, the semivowel [j] facilitates pronunciation.
10. Verbs Ending in -ier
Examples:
- étudier → nous étudions
- oublier → nous oublions
- marier → nous marions
- crier → nous crions
The letter i is pronounced as the semivowel [j].
For example:
- nous étudions → ay-too-dee-yon
- nous crions → cree-yon
The hiatus is therefore greatly reduced.
Exceptions: When French Accepts Hiatus
French does not always eliminate the meeting of two vowels.
Certain words deliberately preserve a hiatus.
1. Words of Learned or Classical Origin
- créer
- réagir
- réélire
- réorganiser
- coopérer
- aérodrome
Pronunciation:
- cré-er
- ré-a-gir
- ré-é-lire
The vowels belong to separate syllables.
2. Words with a Diaeresis (Tréma)
The diaeresis explicitly indicates that two vowels must be pronounced separately.
Examples
Word Approximate Pronunciation Noël No-el naïf na-eef haïr ha-eer maïs ma-ees aiguë ay-goo-uh The diaeresis is a graphic marker of hiatus.
3. Certain Common Words
- chaos
- cacao
- poète
- poésie
- océan
- lion
In these words, the succession of vowel sounds is accepted.
4. Prefixes Such as ré-, pré-, co-
Hiatus is often preserved in order to maintain the structure and meaning of the word.
Examples
- réécrire
- réouvrir
- réorganiser
- réajuster
- coopérer
- coédition
What You Should Remember
French does not completely forbid hiatus, but it has a strong tendency to avoid it.
To do so, it uses:
- Elision: j’aime, l’école;
- Special forms: mon amie, cet arbre;
- Contractions: s’il;
- Liaison: les amis;
- Semivowels (glides): voyons, étudions.
However, some words deliberately preserve hiatus, especially:
- words with a diaeresis (Noël, maïs, haïr);
- words formed with certain prefixes (réécrire, réagir);
- words whose historical development has preserved separate vowels (poésie, chaos, océan).
The rule can therefore be summarized as follows:
French generally prefers to avoid hiatus, but it accepts it when it is necessary to distinguish syllables, preserve meaning, or respect the historical structure of a word.
