You are preparing a birthday card with several people, a group message on WhatsApp, or a banner for a retirement. Everyone wants to sign, and the phrase “we love you” is a must. The problem arises when it comes to writing it: should you change the verb, the pronoun, or both? The answer depends on what you want to say exactly, and especially on who is speaking to whom.
The trap of the pronoun “on” with the verb aimer
The difficulty does not come from the plural itself, but from the pronoun “on.” In French grammar, “on” is always conjugated in the third person singular, even when it refers to a group. Therefore, we write “on aime,” “on part,” “on mange,” never “on aimons” or “on aiment.”

When you write “on t’aime” on a card signed by six people, the conjugation remains the same as that of a single person speaking. The verb “aimer” takes the form “aime,” period. The most common mistake is wanting to mark the plural on the verb, while it is the subject pronoun that carries the collective meaning.
To delve deeper into this point, one can refer to a guide that details how to write on t’aime in the plural with concrete examples of suitable formulations.

The “t'” in “on t’aime” is the contraction of “te.” It indicates that the message is addressed to a single person. If you are addressing multiple recipients, it is this object pronoun that needs to be changed, not the verb’s ending.

Addressing the message to multiple recipients: “on vous aime”
When the group addresses several people (or a single person formally), the phrase becomes “on vous aime.” The verb does not change. The shift to plural occurs through the object pronoun, not through the conjugation.
Let’s take a concrete case: you are writing a thank-you message for two colleagues leaving the company. “On t’aime” no longer works, because “te” refers to a single individual. The correct phrase is “on vous aime.”
When “nous” replaces “on”
If the register is more formal (official letter, speech, solemn text), “nous” replaces “on.” The conjugation then changes radically:
- “Nous t’aimons” for a group addressing a single person informally
- “Nous vous aimons” for a group addressing multiple people or a formally addressed individual
- “On t’aime” and “on vous aime” for a casual or familiar register, with no modification of the verb
The choice between “on” and “nous” depends on the context. On a birthday card among friends, “nous vous aimons” sounds distant. On an invitation or a wedding speech, “on vous aime” may seem too casual.
Common mistakes with “aimer” and personal pronouns
Several mistakes frequently recur in messages written by multiple people. Identifying them allows for correction before sending or printing.
“Je vous aimes” with an -s is a mistake. The verb agrees with the subject “je,” first person singular, so it should be “j’aime” and “je vous aime.” The pronoun “vous” has no influence on the verb’s ending. This confusion between the object complement and the subject is one of the most widespread.
Another trap: writing “on t’aimes” by adding an -s to the verb. With “on,” the verb always takes the ending of the third person singular. We write “on aime,” just like “il aime” or “elle aime.”
The last common mistake: “on vous aimons.” This mix-up comes from the desire to mark the plural of the collective subject, but “on” imposes its own conjugation. Even if “on” refers to ten people, the verb remains in the singular.
Summary of correct forms
| Situation | Casual register | Formal register |
|---|---|---|
| A group → one person (tu) | On t’aime | Nous t’aimons |
| A group → one person (vous) | On vous aime | Nous vous aimons |
| A group → several people | On vous aime | Nous vous aimons |
| One person → several people | Je vous aime | Je vous aime |
Adapting the formula to the medium: card, SMS, speech
The medium changes the game. In an SMS or instant message, “on t’aime” works without any problem, even with abbreviations. On a printed card or an invitation, the question of register arises more.
For a banner, sign, or poster, readability is paramount. “On vous aime” remains the clearest and most direct formula when a group addresses one or more recipients in an informal context.
In a transcribed oral speech (wedding, farewell party, tribute), “nous t’aimons” or “nous vous aimons” brings a seriousness that “on” does not carry. Reactions vary on this point: some find “nous” too formal among close ones, while others consider it more respectful.
- Card among friends or family: “on t’aime” or “on vous aime”
- Speech or official text: “nous t’aimons” or “nous vous aimons”
- Professional message: avoid “aimer” in favor of phrases like “the whole team wishes you the best”
The grammatical rule remains the same regardless of the medium. What varies is the subject pronoun (on/nous) and the object pronoun (te/vous). The verb’s ending follows the subject, never the complement. Keeping this principle in mind is enough to no longer hesitate in front of a card to be signed by multiple people.
