* Sie hat viel Mut gezeigt. (She showed a lot of courage.)
* Der Soldat kämpfte mit Mut. (The soldier fought with bravery.)
* Ich bewundere deinen Mut. (I admire your courage.)
It's important to note that "Mut" is a more formal word than its English counterpart, "courage." In casual conversation, you might use words like "Tapferkeit" (bravery) or "Kopf hoch" (chin up) instead.
