À toi de décider means “it’s up to you to decide” or “your call.” It is a common way in French to hand a decision, a task, or a turn over to someone else. The structure is flexible: the pronoun changes depending on who is being addressed or referred to, and the verb changes depending on what action is being handed over.

The basic structure

The pattern is:

à + stress pronoun + de + infinitive verb

A stress pronoun (also called a disjunctive pronoun) is a pronoun used for emphasis or after a preposition, such as moi, toi, lui, elle, nous, vous, eux, and elles. In this construction, the pronoun tells you whose responsibility or turn it is, and the infinitive tells you what needs to be done.

• À toi de décider. – “It’s up to you to decide.”
• À moi de décider. – “It’s up to me to decide.”
• À lui de décider. – “It’s up to him to decide.”

The sentence can stand on its own, or it can follow a longer statement that sets up the situation.

• J’ai donné mon avis, maintenant à toi de décider. – “I gave my opinion, now it’s up to you to decide.”

Using it with different pronouns

Each stress pronoun shifts who the responsibility falls on.

• À moi de décider. – “It’s up to me to decide.”
• À toi de décider. – “It’s up to you to decide.” (informal, one person)
• À vous de décider. – “It’s up to you to decide.” (formal, or plural)
• À lui de décider. – “It’s up to him to decide.”
• À elle de décider. – “It’s up to her to decide.”
• À nous de décider. – “It’s up to us to decide.”
• À eux de décider. – “It’s up to them to decide.” (masculine or mixed group)
• À elles de décider. – “It’s up to them to decide.” (all-female group)

A name or noun can also replace the pronoun.

• À Marie de décider. – “It’s up to Marie to decide.”
• Aux enfants de décider. – “It’s up to the children to decide.” (note that à combines with les to form aux)

Using it with other verbs

The verb after de can be swapped out to fit almost any handed-over action or responsibility. Here are common ones.

Choisir – “to choose”

• À toi de choisir. – “It’s up to you to choose.”
• À vous de choisir le restaurant. – “It’s up to you to choose the restaurant.”

Jouer – “to play”

This is the standard phrase used in games to say it is someone’s turn.

• À toi de jouer. – “It’s your turn to play.” or “Your move.”
• À nous de jouer. – “It’s our turn to play.”

Voir – “to see”

Used when someone else must judge or work out a situation.

• À toi de voir. – “It’s up to you to see how it goes.” or “You’ll have to judge for yourself.”

Savoir – “to know”

Used when someone alone holds the responsibility for knowing or figuring something out.

• À toi de savoir ce que tu veux. – “It’s up to you to know what you want.”

Agir – “to act”

• À vous d’agir maintenant. – “It’s up to you to act now.”

Parler – “to speak”

• À toi de parler. – “It’s your turn to speak.”

Trouver – “to find”

• À toi de trouver la solution. – “It’s up to you to find the solution.”

Faire – “to do”

• À toi de faire ce que tu penses juste. – “It’s up to you to do what you think is right.”

Related expressions and synonyms

French has several other ways to express the same idea of a turn, task, or decision belonging to someone.

C’est à toi de + infinitive

This is essentially the same structure with c’est added at the front. It is slightly more explicit and often used to open a sentence.

• C’est à toi de décider. – “It’s up to you to decide.”
• C’est à moi de jouer. – “It’s my turn to play.”

C’est ton tour de + infinitive

Used specifically for turns, as in games or sequences of activity.

• C’est ton tour de jouer. – “It’s your turn to play.”
• C’est mon tour de parler. – “It’s my turn to speak.”

Libre à toi de + infinitive

Used to say someone is free to do something, often with a hint that the speaker will not interfere.

• Libre à toi de choisir. – “You’re free to choose.”
• Libre à vous de refuser. – “You’re free to refuse.”

Ça te regarde

A more blunt way to say a matter is someone else’s business, not necessarily framed as a decision.

• Ça te regarde, pas moi. – “That’s your business, not mine.”

Ton choix / ton problème

Short, informal phrases used to hand over responsibility, sometimes with a dismissive tone.

• Ton choix. – “Your choice.”
• Ton problème. – “Your problem.”

Comme tu veux / comme vous voulez

Used when the speaker has no preference and leaves the decision entirely to the other person.

• Comme tu veux. – “As you like.” or “Whatever you want.”
• Comme vous voulez. – “As you like.” (formal, or plural)

A note on tone

À toi de décider and its variants are neutral in tone. They can be used warmly, to give someone space to choose, or more sharply, to signal that the speaker no longer wants to be involved. The meaning depends heavily on context and delivery. Ton choix and ton problème, by contrast, tend to carry a more detached or even irritated tone.
