Linking and elision connect words in speech by reducing the breaks between them. Liaison adds the final consonant of a word before a vowel, while elision removes a final vowel and replaces it with an apostrophe, as in [Silent Letters] and [Sounds and Phonetics]. These two processes are essential for understanding the natural rhythm of French and for avoiding hesitations that disrupt intelligibility. They also become important with [Homophones and Ambiguities], because they strongly modify what the ear perceives.

Obligatory liaison occurs when a final consonant that is normally silent is pronounced before a word that begins with a vowel or a silent h. It is part of the expected pronunciation in very frequent grammatical groups, especially with determiners, pronouns, and certain function words. The most regular consonants are s and x, which yield [z], t and d, which yield [t], n, which remains as [n], and r, which is heard depending on the word.

n se maintient comme en liaison.n remains as [n] in liaison.	mon amiMy friend
r peut se faire entendre selon le mot.The letter r can be heard depending on the word.	premier acteFirst act

Optional liaison appears mainly after a determiner or an adjective in a refined register. It is common in sustained reading, but it can disappear in rapid or familiar speech without preventing understanding. The ear must therefore learn to recognize it as a stylistic possibility, not as a grammatical obligation.

Liaison is forbidden after and, after an aspirated h, before a pause, and before an isolated proper noun. In these cases, the final consonant does not attach to the following word, even if the spelling might seem to allow it. The aspirated h blocks liaison systematically and must be learned word by word, as is also done with certain useful contrasts in [Accents and Accentuation].

IdéeIdea	ExempleExample
La liaison est interdite après et.Liaison is forbidden after et.	toi et elleYou and her
Le h aspiré bloque la liaison.The aspirated h blocks liaison.	des hérosHeroes
Une pause interdit la liaison.A pause forbids liaison.	trois enfantsThree children
Un nom propre isolé ne prend pas de liaison.An isolated proper noun does not take a liaison.	Paris arriveParis arrives

Elision removes a final vowel, most often e, before a vowel or a mute h. It is written with an apostrophe and signals that the word is phonetically shortened, as in [Silent Letters] where the written letter does not always correspond to a distinct sound. Elision is frequent with articles, pronouns, and several very short function words.

IdéeIdea	ExempleExample
Une voyelle finale peut disparaître devant une voyelle.A final vowel may disappear before a vowel.	l’hommeThe man
L’élision s’écrit avec une apostrophe.Elision is written with an apostrophe.	j’aimeI like
Les formes courtes suivent souvent l’élision.The short forms often follow elision.	c’estIt's
L’élision évite le heurt de deux voyelles.Elision avoids the clash of two vowels.	l’amieThe female friend

The apostrophe marks elision and helps distinguish reduced graphical forms from full words. Forms like c’, j’, and l’ should not be read as independent words, as they represent vowel omission. This orthographic distinction supports correct reading and strengthens the relation between writing and sound.

IdéeIdea	ExempleExample
L’apostrophe marque une voyelle supprimée.The apostrophe marks a deleted vowel.	l’écoleThe school
j’ remplace je devant une voyelle.j’ replaces je before a vowel.	j’habiteI live
c’ remplace ce devant une voyelle.c’ replaces ce before a vowel.	c’estIt's
l’ signale l’élision de le ou la.l’ signals the elision of le or la.	l’artisteThe artist

In listening, liaison may resemble a lexical phoneme, especially when it produces [z]. It is therefore necessary to use the grammatical context and the sentence structure to distinguish a liaison consonant from a true sound belonging to the word. This attention is essential with [Sounds and Phonetics], because the ear must learn to link sound form and grammatical function.

IdéeIdea	ExempleExample
La liaison peut ressembler à un z lexical.The [z] liaison can resemble a lexical z.	les amisThe friends
Le contexte grammatical aide à identifier la liaison.The grammatical context helps identify the liaison.	deux oiseauxTwo birds
La phrase entière clarifie le son perçu.The entire sentence clarifies the perceived sound.	très agréableVery pleasant

To succeed with liaison, you must release the final consonant of the preceding word and attach it to the following vowel without a noticeable break. The articulatory gesture must remain light and continuous, especially in read-aloud and shadowing. Good coordination of the mouth and breath also improves the fluency of words linked by elision.

IdéeIdea	ExempleExample
La consonne finale se détache puis rejoint la voyelle suivante.The final consonant detaches and then joins the following vowel.	petit amiBoyfriend
Le souffle reste continu.Breath remains continuous.	nous arrivonsWe arrive
La lecture à voix haute aide à stabiliser le geste.Reading aloud helps stabilize the gesture.	vous aimezYou like
Le shadowing renforce l’enchaînement naturel.Shadowing reinforces the natural chaining.	très utileVery useful

To learn effectively, one must first master obligatory liaisons, then recognize mute and aspirated h, and finally avoid forbidden liaisons. Optional liaisons come next, because they depend more on register and rate. This hierarchy provides a solid basis for listening comprehension and for careful pronunciation.

IdéeIdea	ExempleExample
Les liaisons obligatoires sont la première priorité.Obligatory liaisons are the first priority.	les enfantsThe children
Le h muet et le h aspiré doivent être distingués.The mute h and the aspirated h must be distinguished.	l’hommeThe man
Les liaisons interdites doivent être évitées.Forbidden liaisons must be avoided.	et elleAnd she
Les liaisons facultatives dépendent du registre.Optional liaisons depend on the register.	un excellent amiAn excellent friend

In Quebec French and in several informal usages, some formal liaisons are less frequent than in careful pronunciation. In rapid speech, even accepted liaisons can be reduced or omitted without the sentence becoming incorrect from a communicative point of view. The written standard remains useful for understanding the expectations of reading and of sustained speech.

IdéeIdea	ExempleExample
Le français québécois réduit souvent certaines liaisons formelles.Québécois French often reduces some formal liaisons.	mes amisMy friends
Le registre familier omet plus facilement la liaison.The informal register more easily omits the liaison.	trop intéressantToo interesting
Le discours rapide allège les enchaînements.Rapid speech lightens the linkages.	des enfantsSome children

Liaison links a final consonant to the next word, elision removes a vowel, and the two processes serve to smooth the spoken chain. It is important to note the difference between obligatory, facultative, and forbidden liaisons, as well as the decisive role of the aspirated h and of the apostrophe. Regular practice of reading aloud, shadowing, and auditory discrimination solidifies these automatisms and prepares the connections with [Homophones and Ambiguities].
