French -yer Verbs: The y to i Swap (payer, envoyer)
Grammar Rule in 30 Seconds
For verbs ending in -yer, change the 'y' to an 'i' for all forms except 'nous' and 'vous'.
- Change y to i for je, tu, il/elle/on, and ils/elles forms.
- Keep the y for the nous and vous forms.
- This rule applies to common verbs like payer, envoyer, and nettoyer.
Overview
French verbs ending in -yer present a unique conjugation pattern, particularly in the present tense. Unlike regular -er verbs, these verbs often undergo a y to i stem change before certain endings. This linguistic shift is not arbitrary; it serves a crucial phonetic purpose in French, ensuring smooth pronunciation and maintaining clarity of sound.
The y in -yer verbs functions phonetically as a semivowel, similar to a double i (ii). Its transformation to i is a mechanism to preserve the pronunciation of the preceding consonant sound when it's followed by a silent e. Understanding this underlying phonetic principle is key to mastering these common verbs, which include essential terms like payer (to pay) and envoyer (to send).
This rule applies consistently across various situations, making it a foundational element for A1 French learners.
How This Grammar Works
y of -yer verbs transforms into an i when it precedes an unpronounced e. This specific change occurs with the endings -e, -es, -e, and -ent for the subject pronouns je, tu, il/elle/on, and ils/elles respectively. These endings are phonetically silent, meaning they are written but not audibly pronounced.y, the consonant preceding it would risk an awkward or unclear pronunciation. By changing y to i, the verb's stem maintains a clear vowel sound before the silent ending, facilitating natural speech.y is followed by a pronounced vocal ending, typically -ons for nous and -ez for vous, the y remains unchanged. These vocal endings provide sufficient phonetic support, allowing the y to retain its semivowel sound without difficulty. This consistent pattern simplifies conjugation: if the ending is silent, change y to i; if the ending is vocal, keep y.j'envoie (silent -e) with nous envoyons (vocal -ons). The pronunciation drives the spelling.-yer verbs:- Verbs ending in
-oyer(e.g.,envoyer,nettoyer- to clean) and-uyer(e.g.,appuyer- to press) always undergo theytoichange for silent endings. This rule is obligatory. - Verbs ending in
-ayer(e.g.,payer,essayer- to try) offer flexibility. You may either change theytoior keep theybefore silent endings. Both forms are grammatically correct and widely accepted, though theiform (je paie) is often perceived as slightly more formal or traditional, while theyform (je paye) is more common in modern, everyday usage. For instance, you can sayje paieorje payefor 'I pay'.
Formation Pattern
-yer verbs in the present tense involves a systematic process. This pattern ensures correct pronunciation while adhering to French orthographic rules. Let's outline the steps using envoyer (an -oyer verb) and payer (an -ayer verb) as examples.
-er ending from the infinitive to find the base stem.
envoyer (to send), the stem is envoy-.
payer (to pay), the stem is pay-.
je, tu, il/elle/on, nous, vous, ils/elles) dictates the ending and potential stem change.
y to i Change (if applicable)
je, tu, il/elle/on, ils/elles (which have silent endings):
-oyer or -uyer, change the y in the stem to an i. For envoy-, this becomes envoi-.
-ayer, you have a choice: either change y to i (e.g., pai-) or keep the y (e.g., pay-).
nous and vous (which have vocal endings), the y always remains. The stem for envoyer stays envoy-, and for payer it stays pay-.
-er verb endings to the modified or unmodified stem.
envoyer (stem envoi- or envoy-) | payer (stem pai- or pay-) |
je | -e | j'envoie | je paie / je paye |
tu | -es | tu envoies | tu paies / tu payes |
il/elle/on | -e | il envoie | il paie / il paye |
nous | -ons | nous envoyons | nous payons |
vous | -ez | vous envoyez | vous payez |

When To Use It
-yer verbs are frequently used in daily French communication, making their correct conjugation essential from the A1 level. You will encounter these verbs in a wide range of contexts, from basic transactions to modern digital interactions. Familiarize yourself with their meanings and typical applications.-yer verbs and example usages:envoyer(to send): This verb is indispensable for any form of communication.J'envoie un email.(I am sending an email.)Tu envoies un message à tes amis.(You send a message to your friends.)Ils envoient des colis partout.(They send packages everywhere.)payer(to pay): Crucial for financial transactions.Je paie en espèces.(I pay in cash.) orJe paye en carte.(I pay by card.)Combien vous payez pour le loyer ?(How much do you pay for rent?)Nous payons toujours à l'heure.(We always pay on time.)essayer(to try, to try on): Used for attempts or fitting clothes.J'essaie de comprendre.(I am trying to understand.)Elle essaie cette robe.(She is trying on this dress.)Vous essayez une nouvelle recette.(You are trying a new recipe.)nettoyer(to clean): Pertains to household chores or general cleaning.Tu nettoies la cuisine ?(Are you cleaning the kitchen?)Nous nettoyons la maison chaque semaine.(We clean the house every week.)appuyer(to press, to lean on): For physical actions involving pressure.Il appuie sur le bouton.(He presses the button.)J'appuie ma main sur la table.(I lean my hand on the table.)
When Not To Use It
y to i swap does not apply, to avoid overgeneralizing this rule. This primarily concerns two situations:nousandvousforms: As previously established, theynever changes toifornousandvousin the present tense of-yerverbs. Their vocal endings (-onsand-ez) provide clear phonetic support for they. For example, it isnous envoyons, nevernous envoions. Similarly, it isvous payez, notvous paiezorvous payiez(which would be confusing with the imperfect subjunctive).
- Verbs not ending in
-yer: This rule is specific to verbs ending in-yer. Do not apply it to other verbs, even if they contain ayelsewhere in their stem or infinitive. For instance, verbs likecroire(to believe) orvoir(to see) do not exhibit thisytoichange. Also, verbs likeétudier(to study), which already contain anibefore the-erending, are regular-erverbs in their stem and do not undergo anyytoitransformation because there is noyin the position that would trigger it. J'étudie le français.(I study French.) - Correct.Je étuidie le français.- Incorrect; noyto swap.
Common Mistakes
-yer verbs. Being aware of these pitfalls will help you avoid them and refine your French.- Changing
ytoifornousandvous: This is perhaps the most common error. Remember that theyremains fornousandvousdue to their vocal endings. For example, writingnous envoionsinstead ofnous envoyonsis incorrect. Always double-check these two forms.
- Forgetting the
ytoichange foril/elle/onandils/elles: Whilejeandtuforms are often practiced, learners sometimes forget the mandatory change for the third-person singular and plural, especially with the silent-entending. For instance,ils payent(withy) is generally acceptable for-ayerverbs, butils envoye(withy) forenvoyeris definitively wrong; it must beils envoient(withi).
- Pronouncing the silent
-ent: Many learners, influenced by other languages, attempt to pronounce the-entending inils/elles envoientorils/elles paient. In French, this ending is always silent in the present tense. The pronunciation ofils envoientis identical toil envoie, which sounds likeahn-vwah. The-entmerely marks the third-person plural subject.
- Applying the mandatory
ytoirule to-ayerverbs: Whileje paieis correct,je payeis also correct and often preferred in contemporary usage. Insisting on theichange for-ayerverbs can be seen as slightly antiquated by some native speakers, although it is never truly wrong. Be mindful of this flexibility.
- Confusing
-yerverbs with verbs requiringetoèaccent changes: Verbs likeacheter(to buy) orlever(to lift) changeetoèin their stem (e.g.,j'achète). This is a different phonetic rule, driven by a different need to open the vowel sound before a silente. Do not mix these patterns;-yerverbs involveytoi, not accent marks. For example,j'achèteis correct,j'envoyeis incorrect.
Memory Trick
To consistently apply the y to i rule, a helpful mnemonic device is the "Boot" or "Shoe" Conjugation. Imagine a boot drawn around the conjugation table:
```
+-----------+
| je |
| tu |
| il/elle/on |
+-----------+
| |
| |
+-----------+
| ils/elles |
+-----------+
```
The forms of the verb that fall inside the boot (je, tu, il/elle/on, and ils/elles) are the ones that undergo the y to i stem change (for -oyer/-uyer verbs, or optionally for -ayer verbs). These are the forms where the verb ending is silent.
The forms that fall outside the boot (nous and vous) retain the original y in their stem. These are the forms where the verb ending (-ons and -ez) is pronounced.
This visual trick helps reinforce which forms require the stem change and which do not, based on the phonetic nature of their endings. The "boot" represents the "silent zone" of the verb, where the y needs to transform for clarity.
Real Conversations
Understanding how -yer verbs are used in authentic French contexts goes beyond textbook examples. Pay attention to how native speakers integrate them into casual conversations, social media, and professional communication.
- Digital Communication:
- Salut ! Je t'envoie les photos de la soirée. Tu les reçois bien ? (Hi! I'm sending you the party photos. Are you receiving them okay?)
- On s'envoie des messages toute la journée. (We send each other messages all day.)
- Il m'a envoyé un lien intéressant. (He sent me an interesting link.) - Note: envoyé here is the past participle, showing the stem envoy- before the past participle ending é.
- Everyday Transactions:
- Je paie l'addition, c'est bon. (I'll pay the bill, it's fine.) or Je paye la course. (I'll pay for the ride/errand.)
- Vous payez par carte ou en espèces ? (Are you paying by card or in cash?)
- Combien tu paies pour ton café chaque matin ? (How much do you pay for your coffee every morning?)
- Actions and Attempts:
- J'essaie de me concentrer, mais c'est difficile. (I'm trying to concentrate, but it's difficult.)
- Elle essaie un nouveau sport. (She's trying a new sport.)
- Appuie fort sur ce bouton pour démarrer. (Press hard on this button to start.)
Notice the natural flow and idiomatic expressions. For payer, both je paie and je paye are used interchangeably, reflecting the optional nature of the change in spoken French. The context clarifies the meaning, and the usage reflects the dynamic nature of language.
Contrast With Similar Patterns
-yer rule from these to avoid confusion.- Regular
-erVerbs: The vast majority of French verbs end in-erand are considered regular. They follow a straightforward conjugation without any stem changes. For example,parler(to speak): Je parle(I speak)Nous parlons(We speak)
parl- remains consistent. -yer verbs deviate from this regularity specifically due to the phonetic requirements of the y and its interaction with silent endings. This highlights that -yer verbs are a sub-category of -er verbs with a specific adjustment.- Verbs with
etoèAccent Change: Many other-erverbs, particularly those with anein the second-to-last syllable of their stem (e.g.,acheter- to buy,lever- to lift,préférer- to prefer), change thateto anèwhen the followingeending is silent. J'achète(I buy) vs.nous achetons(we buy)Je préfère(I prefer) vs.nous préférons(we prefer)
e to è before a silent syllable, preventing an awkward or closed sound. While both -yer verbs and e to è verbs involve stem changes for phonetic reasons, the specific letter transformation (y to i vs. e to è) and the underlying mechanism are distinct.y to i rule to these verbs, nor the e to è rule to -yer verbs.- Verbs ending in
-ier: Verbs likeétudier(to study) already contain anibefore the-erending. They conjugate as regular-erverbs because they do not have aythat needs to be modified. J'étudie(I study)Nous étudions(We study)
y to i change is exclusively triggered by the presence and position of the y in the -yer ending.Progressive Practice
Integrating -yer verbs into your active French vocabulary requires deliberate practice. Start with simple exercises and gradually increase complexity.
- Conjugation Drills: Systematically conjugate common -oyer, -uyer, and -ayer verbs through all pronouns. Say them aloud to internalize the sound changes. Focus initially on envoyer and payer.
- Sentence Building: Create your own sentences using these verbs in various contexts. For example, J'envoie un message à ma mère. (I send a message to my mother.) or Nous payons nos factures. (We pay our bills.)
- Listen and Repeat: Find native French speakers using these verbs (e.g., in podcasts, videos). Pay close attention to the pronunciation differences, especially the silent -ent and the retained y in nous/vous forms. Repeat after them.
- Self-Correction: When writing or speaking, pause and ask yourself: "Is the ending silent or vocal? Does this verb end in -oyer, -uyer, or -ayer?" This mental check will help solidify the rule.
Consider the cultural aspect of payer: In France, paying for things is a daily ritual, often involving exact change or contactless payment. Mastering payer allows you to navigate these social interactions seamlessly.
Quick FAQ
- Q: Is the
ytoichange mandatory for all-yerverbs? - A: No. It is mandatory for verbs ending in
-oyer(e.g.,envoyer) and-uyer(e.g.,appuyer). For verbs ending in-ayer(e.g.,payer,essayer), the change is optional; bothyandiforms are correct (je paieorje paye).
- Q: How do I pronounce
ils envoient? - A: You pronounce
ils envoientexactly likeil envoie. The-entending is silent. The liaison withilsmeans you pronounce thesofilsas azsound:eelz-ahn-vwah.
- Q: Does this rule apply in tenses other than the present?
- A: This specific
ytoistem change pattern primarily applies to the present tense and the future/conditional stems for some-yerverbs (which also involve ani). However, in composite tenses like thepassé composé, you use the past participle (e.g.,envoyé,payé), where theyremains.
- Q: What is the main reason for this
ytoiswap? - A: The main reason is phonetic. The change from
ytoiensures that the preceding consonant sound is clearly pronounced before a silenteending, facilitating smoother and clearer articulation in spoken French.
- Q: Can
payeralso mean 'to pay for'? - A: Yes,
payeroften directly translates to 'to pay for' without needing an additional preposition. For example,je paie le cafémeans 'I pay for the coffee'.
- Q: Are there any verbs that look like
-yerverbs but aren't? - A: Verbs like
croireorvoircontainoiorysounds but are not-yerverbs and follow different conjugation patterns. Always check the infinitive ending to identify-yerverbs correctly. Only verbs ending specifically in-yerare subject to this rule. Ensure you are looking at the full infinitive, not just a phonetic resemblance.

It's a spelling convention to maintain the sound of the stem before a silent 'e'.
It's a common variant, but 'paie' is the standard form.
Yes, almost all of them follow this rule.
It follows the same rule: j'envoie, nous envoyons.
You will see it in informal writing, but it's better to use 'i' in formal contexts.
Because the ending '-ons' starts with a vowel, so the 'y' is needed.
No, it's a very consistent rule once you practice it.
Very few, but most -yer verbs follow this pattern perfectly.
