Other forms: discouragedly
If you work and work on a project and never seem to make any progress, you may feel discouraged, meaning your enthusiasm and optimism have been replaced by doubt and negativity.
If you’ve ever felt discouraged, you won’t be surprised to learn that the word’s French origins refer to courage that has being taken away. The adjective describes people who no longer feel that good things will happen, such as discouraged job-seekers, who despite sending hundreds of applications to prospective employers, never get any responses. They may have "lost the courage" to keep looking for work.
