"Set back" means when something happens that causes a delay or a problem in a plan or a task. For example, if you were planning to go on a trip, but then you got sick, that would be a "set back" because it would delay your travel plans. Or, if you were building a house and then you realized that the foundation wasn't stable, that would be a "set back" because it would cause a problem in the construction. Basically, "set back" means something that makes things harder or slower.
