In French, the word for “sir” is “monsieur.” This term is commonly used as a polite form of address for men and is equivalent to the English “Mr.” or “sir.”
When you greet someone formally or show respect, using “monsieur” is appropriate. For example, if you were to address a man you are meeting for the first time, you might say, “Bonjour, monsieur,” which means “Hello, sir.” It’s a straightforward yet important word in French etiquette, indicating respect and formality in conversations.
