How do you say Hello Master in french?

There's no direct translation for "Hello Master" in French that would be considered polite or respectful.

Here's why and some alternatives depending on the context:

* "Master" has connotations of servitude and hierarchy that are not common in French culture. It would be considered very formal and potentially disrespectful.

* "Maître" (Master) is used in specific contexts:

* Professional titles: "Maître d'hôtel" (head waiter), "Maître artisan" (master craftsman)

* Legal context: "Maître" is used before a lawyer's name (e.g., Maître Dupont)

* Formal Greetings: "Bonjour" (good morning/day), "Bonsoir" (good evening) are the standard polite greetings.

If you're addressing someone in a position of authority, consider these alternatives:

* "Bonjour Monsieur/Madame" (Good morning/day Sir/Madam) - Very polite and respectful.

* "Bonjour [Title] [Last Name]" (Good morning [Title] [Last Name]) - Example: "Bonjour Monsieur le Directeur" (Good morning Mr. Director).

* "Salut" (Hi) - Informal and friendly, but only use with people you know well.

Please provide more context about who you're addressing and the situation, and I can offer more specific advice.
