Understanding Liaisons in French Verb Conjugations

You can know a French verb table perfectly and still sound unnatural the moment you put that verb into a sentence. That’s because French verb pronunciation doesn’t live inside isolated conjugation charts — it changes at the edges, where words meet. Liaisons are one of the biggest reasons learners hear one thing, read another, and then freeze when they try to speak.

Quick answer: in French verb conjugations, a liaison happens when a normally silent final consonant gets pronounced before a following word that starts with a vowel or silent h. Some liaisons are mandatory, some are optional, and some sound wrong or overly formal if you force them. If you want your spoken French to sound smoother, you need to learn verbs in full phrases, not one form at a time.

Why liaisons matter more for verbs than most learners expect

When English speakers first learn French, they usually focus on endings on the page: -e, -es, -ent, -ons, -ez. But spoken French often hides those endings, reshapes them, or only reveals them in connected speech. That’s why you may clearly understand nous avons in a lesson, then miss it in a film because the liaison makes it sound like one moving unit: nou-zavon.

Verb phrases are especially important because they appear constantly in everyday speech. High-frequency combinations like ils ont, elles arrivent, nous allons, and on est come up far more often than rare formal structures. Corpus-based frequency lists consistently show verbs like être, avoir, aller, faire, and dire among the most common verbs in French, so the sound links around them matter immediately for comprehension and speaking.

If you only memorise isolated forms from French conjugation tables, you may recognise the verb visually but still fail to produce it smoothly. That’s exactly why, at VerbPal, we focus on active production in full contexts. Our drills ask you to type and produce the form under pressure, not just recognise it, which is where liaisons actually become automatic. Because we use spaced repetition based on the SM-2 algorithm, the chunks you struggle with come back at the right time instead of disappearing after one easy review.

Pro Tip: Don’t learn ont as just “they have.” Learn ils ont, elles ont, ils ont eu, and ils ont un problème (they have a problem) as sound patterns.

What a liaison actually is in French

A liaison happens when a final consonant that is usually silent gets pronounced because the next word begins with a vowel sound or a silent h.

Take this basic contrast:

• Ils parlent. (They speak.) 🔊
• Ils parlent anglais. (They speak English.) 🔊

In the first sentence, the final -ent in parlent is silent. In the second, you still do not pronounce a liaison after parlent — and that’s a crucial point. Not every written final consonant can link forward. French liaison follows patterns, not spelling alone.

Now compare that with:

• Ils ont faim. (They are hungry./They have hunger.) 🔊

Here, the s in ils links to ont, creating a /z/ sound: il-zont.

The three categories you need

For learners, the simplest useful framework is:

1. Mandatory liaison — native speakers normally make it.
2. Optional liaison — possible, often formal, but not always used in everyday speech.
3. Forbidden liaison — making it sounds wrong.

This matters because many learners think “more liaison = more French.” Usually, the opposite is true. Too many liaisons can make you sound like you’re reading a grammar book out loud.

At VerbPal, this is why we don’t stop at bare infinitives or isolated tables. We cover French across all tenses, irregulars, reflexives, and the subjunctive, but we push you to retrieve forms inside usable phrases, because that is where pronunciation patterns like liaison live.

Pro Tip: Ask yourself “What word usually comes before or after this verb form?” That question helps more than staring at the written ending.

Mandatory liaisons you’ll hear all the time with verbs

These are the liaisons you should expect in normal, careful spoken French. If you skip them, your speech sounds choppy. If you’re listening for them, your comprehension improves fast.

Subject pronoun + verb

This is the single most useful liaison zone for verb learners.

• Ils ont déjà mangé. (They have already eaten.) 🔊
• Elles arrivent à midi. (They arrive at noon.) 🔊
• On est prêts. (We’re ready./One is ready.) 🔊
• Nous avons une idée. (We have an idea.) 🔊
• Vous êtes en avance. (You are early.) 🔊

The common sounds are:

• s or x often become /z/ in liaison
• d can become /t/ in some fixed cases like grand homme, but that matters less for verb conjugation
• n may be pronounced in some contexts, especially with determiners, but again less central here than pronoun + verb links

Here are some core verb combinations worth learning as whole chunks:

Auxiliaries in common spoken patterns

Liaisons show up constantly with avoir and être because these verbs anchor the passé composé and many everyday expressions.

• Ils ont fini. (They finished.) 🔊
• Elles ont étudié. (They studied.) 🔊
• On est arrivés. (We arrived./One arrived.) 🔊
• Vous avez oublié. (You forgot.) 🔊

If past-tense auxiliary choice still trips you up, our posts on why some French verbs use être in the passé composé and avoir vs être mistakes in the French past tense pair naturally with this topic.

One practical way we train this in VerbPal is by making you retrieve these auxiliary chunks repeatedly in writing and typing, not just tap through them. That matters because if you can produce ils ont fini from memory, you are much more likely to pronounce the liaison naturally when speaking.

Pro Tip: Build a shortlist of 10 “glue pairs” with high-frequency verbs and repeat them aloud daily until they feel like single words.

Optional liaisons: possible, but not always natural

Optional liaisons are where learners often go wrong. Yes, they exist. No, you do not need to pronounce all of them. In casual modern spoken French, many optional liaisons get dropped, especially in everyday conversation.

This is especially true after certain verb forms, particularly plural verb forms before a following vowel.

After plural verb forms

Consider:

• Ils arrivent à huit heures. (They arrive at eight o’clock.) 🔊

There is a mandatory liaison between ils and arrivent: il-zarrivent. But between arrivent and à, liaison is generally optional and often avoided in ordinary speech. Many speakers will not pronounce a final /t/ there.

The same pattern appears with:

• Ils parlent anglais. (They speak English.) 🔊
• Elles travaillent ici. (They work here.) 🔊

In standard everyday French, you should not force a liaison after these verb forms just because the next word starts with a vowel. Overdoing this can sound overly formal, theatrical, or simply incorrect depending on the structure.

In more formal speech

Some optional liaisons appear more often in speeches, newsreading, or highly careful pronunciation:

• Nous sommes arrivés. (We arrived.) 🔊
• Ils sont arrivés. (They arrived.) 🔊

Even here, what matters most is not trying to sound “advanced” by adding every possible link. What sounds advanced is choosing the liaison patterns native speakers actually use. In our experience, adult learners progress faster when they master the high-value mandatory patterns first and leave edge-case optional liaisons for later review.

Pro Tip: If you’re unsure whether a liaison after a verb is optional, your safest spoken default is usually to skip it unless you’ve heard that exact chunk often from native speech.

Forbidden liaisons that make verb pronunciation sound wrong

Some liaisons are simply not done in standard French. This is where spelling can mislead you badly.

After singular nouns or certain forms before verbs

For example:

• Le héros arrive. (The hero arrives.) 🔊

Because héros has an aspirated h, you do not make liaison. The same principle matters with many words that begin with aspirated h, even though the h itself is not pronounced.

After et

A classic forbidden liaison:

• Paul et Anne arrivent. (Paul and Anne are arriving.) 🔊

You do not pronounce et as linking forward.

After many verb forms before a noun or adverb

This is the area most relevant to verb conjugations. Learners often see a written consonant and try to link it:

• Ils parlent anglais. (They speak English.) 🔊
• Il finit avec nous. (He finishes with us.) 🔊

These are not places where you should casually invent a liaison.

If pronunciation mismatches keep confusing you, our posts on why the -ent ending in French verbs is silent, French pronunciation and spelling mismatch, and common French spelling mistakes in the present tense will help you connect what you see to what you actually hear.

Pro Tip: Never assume a final written consonant creates liaison. French liaison is a usage pattern, not a spelling rule.

How liaisons change what verb forms sound like in real sentences

This is where French learners often feel cheated by the language. You memorise one form, but the sentence sounds different in real life.

Example 1: ont almost never arrives alone

• Ils ont un chat. (They have a cat.) 🔊

What your ear often catches is not ont as an isolated unit, but the whole chain:

• ils ont → /il zɔ̃/
• ont un → nasal vowel flowing into the next word
• full phrase rhythm instead of separate blocks

Example 2: est changes depending on the subject

• Il est ici. (He is here.) 🔊
• On est ici. (We’re here./One is here.) 🔊
• Vous êtes ici. (You are here.) 🔊

The verb is related, but the sound pattern changes depending on what comes before it.

Example 3: plural subjects often reveal the sentence structure

• Ils aiment apprendre. (They like learning.) 🔊

The liaison between ils and aiment helps your ear identify the plural subject immediately. That matters because many French verb forms sound identical in isolation. We cover that broader issue in il parle vs ils parlent pronunciation.

When learners practise these as full prompts in VerbPal, they stop treating ont, est, and aiment as separate dictionary items and start hearing them as sentence-level patterns. That shift is what makes listening and speaking feel less random.

Pro Tip: When you learn a new verb form, immediately pair it with a subject and a short continuation: ils ont, on est là (we’re here), vous êtes prêts (you are ready).

A practical drill routine for mastering French liaisons with verbs

You do not need a giant phonetics course to improve this. You need a small set of reliable habits.

1. Practise verb chunks, not isolated forms

Instead of drilling:

• ont
• avons
• êtes

Drill:

• Ils ont. (They have.) 🔊
• Nous avons. (We have.) 🔊
• Vous êtes. (You are.) 🔊

Then extend:

• Ils ont raison. (They are right.) 🔊
• Nous avons essayé. (We tried.) 🔊
• Vous êtes arrivés. (You arrived.) 🔊

2. Separate mandatory from optional

Make two lists:

Mandatory

• ils ont (they have)
• elles arrivent (they arrive)
• nous avons (we have)
• vous êtes (you are)
• on est (we are / one is)

Optional / don’t force it

• after many plural verb forms before a vowel in running speech

This stops you from wasting energy on low-value pronunciation details.

3. Use active recall out loud

Look at the English and produce the French aloud:

• “They have a meeting.” → Ils ont une réunion. (They have a meeting.) 🔊
• “We are here.” → On est là. (We are here./One is here.) 🔊
• “You are ready.” → Vous êtes prêts. (You are ready.) 🔊

This is exactly the kind of production work we built VerbPal for. Passive recognition won’t make these sound patterns automatic. Saying them from memory will.

4. Listen for liaisons in high-frequency verbs first

Start with:

• être (to be)
• avoir (to have)
• aller (to go)
• faire (to do/make)
• aimer (to like/love)

These verbs appear so often that a small amount of focused listening gives you a big return.

Pro Tip: Record yourself saying 10 high-frequency liaison chunks. Compare them to native audio. The gap becomes obvious fast — and fixable.

Put it into practice

Theory helps, but liaisons only stick when you have to produce them repeatedly. That is why our approach at VerbPal centres on active recall: you type, write, and say the form instead of guessing from multiple choice. For pronunciation-heavy patterns like ils ont, nous avons, and vous êtes, that difference matters.

Because VerbPal schedules reviews with SM-2 spaced repetition, the chunks you hesitate on come back more often, while the ones you already own fade into the background. And because we cover French verbs broadly — from core present-tense forms to irregulars, reflexives, compound tenses, and the subjunctive — you are not learning liaison as a random side topic. You are learning it where it actually appears: inside real verb usage.

If you want a simple routine, do this:

1. Pick 10 high-frequency liaison chunks.
2. Produce them from English prompts.
3. Extend each one into a short sentence.
4. Review them daily until the link sounds automatic.

Pro Tip: If a chunk feels awkward, don’t just replay it. Produce it from memory three times in a row: once slowly, once at natural speed, once inside a longer sentence.

The biggest mistakes English speakers make with French liaisons

Mistake 1: Pronouncing every written consonant

French spelling is not a pronunciation script. If you say every final consonant you see, you’ll sound robotic.

Mistake 2: Learning verbs from tables only

Tables help you organise forms, but they don’t teach connected speech. That’s one reason many learners plateau. If this sounds familiar, read why conjugation tables are slowing you down.

Mistake 3: Ignoring pronunciation until “later”

Later never comes. If you build the wrong sound habits early, they get harder to fix. You don’t need perfect phonetics now, but you do need the major patterns.

Mistake 4: Treating optional liaisons as a badge of fluency

Real fluency is not “maximum liaison.” Real fluency is sounding natural in context.

Mistake 5: Only recognising, never producing

You might hear ils ont and understand it, but still say eel on awkwardly when speaking. That’s why our Learn French with VerbPal approach prioritises active recall and repeated production over passive exposure alone.

Pro Tip: If you can’t produce a liaison chunk within two seconds, you don’t own it yet. Keep drilling it in context.

FAQ: Understanding liaisons in French verb conjugations

Are liaisons with French verbs always pronounced?

No. Some are mandatory, especially in common pronoun + verb combinations like ils ont or nous avons. Others are optional, and many are avoided in everyday speech.

What is the most important liaison to learn first?

Start with subject pronoun + vowel-initial verb combinations:

• ils ont (they have) 🔊
• elles arrivent (they arrive) 🔊
• nous avons (we have) 🔊
• vous êtes (you are) 🔊

Do I need to pronounce optional liaisons to sound fluent?

No. In fact, forcing too many optional liaisons can make you sound unnatural. Consistent control of mandatory liaisons matters much more.

Why do liaisons matter for verb conjugation if they’re not part of the table?

Because spoken French happens in sentences, not charts. Liaisons help mark subjects, smooth rhythm, and make high-frequency verb phrases sound the way native speakers actually say them.

What’s the best way to practise them?

Use short, high-frequency sentence chunks and say them from memory. A purpose-built drill system works better than passive review. At VerbPal, we use spaced repetition and active production so the right verb phrases come back exactly when your memory needs reinforcement.
