How to say "hello" in French ? Have you ever wondered which word to choose, between “bonjour”, “salut”, or “bonsoir” ? To choose the right word, there are two things to take in consideration : who you are speaking to, and what time of the day it is. 1. Who are you saying "hello" to ? – To someone you don’t know, or not very well ; a shopkeeper, a teacher, a colleague you are not close to or a hierarchic superior, a neighbour…→ « Bonjour » is the good word. – To someone that is closer to you, friend, family, a colleague with whom you also have informal conversation…→ « Salut » is the good choice ! 2. What time is it ? – « Salut » can be used at any time of the day or night.– « Bonjour » is used all day.
