la mou courage

You use the correct form bon courage as a standalone exclamation. You can say it when someone is heading to a meeting. You can say it when a friend starts cleaning their messy kitchen. It works best at the moment someone begins a challenge. Just drop it into conversation as they walk away. It shows you recognize their effort. Don't worry about the mou sound; focus on the bon!

Use it when your friend has a long drive ahead. Use it when a colleague has a mountain of paperwork. It is perfect for students right before an exam. It is also great for small daily struggles. If you see someone struggling with heavy grocery bags, say it. It is a very supportive and kind thing to say. It builds a quick bridge of empathy between people.

Do not use it for games of pure chance. If someone is playing the lottery, use bonne chance instead. Bon courage implies work is involved. Don't use it if the situation is already over. It is for the future or the present struggle. Also, avoid saying mou (soft) unless you want to be funny. Calling someone's courage 'soft' might hurt their feelings! Keep it positive and firm.

The French value the idea of 'effort' and 'willpower' very highly. This phrase reflects a culture that respects the grind of daily life. It is not just a polite filler word. It is a genuine acknowledgment of the 'work' required to live. You will hear it dozens of times a day in France. It is almost as common as saying hello or goodbye. It is the verbal equivalent of a supportive pat on the back.

The most important variation is the correct one: bon courage. You might also hear bon courage à tous for a group. Sometimes people say courage ! on its own for extra punch. If the task is really hard, they might say grand courage. In text messages, you might see people just use a muscle emoji. Always aim for the 'B' sound to avoid the 'soft' mistake.
