The main language spoken in France is French. However, many people speak English here as well. A large number of people in France speak multiple languages and because Grenoble is so close to Italy, it is very common to find people with Italian heritage who also speak Italian. The Italian influences are also seen in the food in Grenoble as well! When speaking to someone in France, it is very important to greet them first with a simple Bonjour! (Hello) before you begin talking or asking a question. Saying a quick hello is a sign of respect and is part of the French experience to say it many times throughout the day.
