tired
'müde' and 'unermüdlich' are clear opposites. 'müde' says that someone needs rest or sleep and no longer has full energy. 'unermüdlich', on the other hand, describes someone who keeps going for a very long time and hardly lets up. The word often fits people who work, help, or fight with a lot of endurance. So 'müde' describes a state, while 'unermüdlich' is more about a strong attitude or lasting energy.
