Why does saying learning hard sound so terribly wrong and unnatural, given that working hard, exercising hard, listening hard, thinking hard, and even it rains hard sound perfectly natural and get said all the time?
I know that we can add hard to something when we’re talking about doing something hard to accomplish or doing something with a lot of effort.
Then why can’t I just learn hard?
Sometimes learning something can be very challenging, or I can try to do the act of learning so hard like studying hard and working hard with a lot of effort and energy.
Why shouldn’t “learning hard” be the act of “doing hard”?
