Student or Learner
Would you tell me whether I am right about my interpretation of the expression in bold in the following sentences?
We have started the course with twenty-five students, but that does not mean that they will all complete it; we always expect a certain number to fall by the wayside.
The boys tried to make a 50-mile hike, but most of them fell by the wayside.
fall by the wayside = suffer a setback, give up something at halfway, walk out someone at halfway, drop out before the time
Thanks for your efforts.
