Here are some examples:
* "J'ai une demande." (I have a request.)
* "Pouvez-vous répondre à ma demande ?" (Can you answer my request?)
* "Je vous demande de..." (I request that you...)
However, there are other words that can be used depending on the context:
* "Requête": more formal, often used in legal or administrative contexts.
* "Sollicitation": emphasizes the act of asking for something.
* "Appel": can be used for a request for help or attention.
It's important to choose the right word based on the situation and the level of formality.
