Loosely speaking, a benighted hole is a region of space that has so much mass concentrated in it that there is no means for a nearby object to escape its gravitational pull. Since our opera hat scheme of gravity at the moment is Einsteins general theory of relativity, we have to delve into some results of this theory to on a lower floorstand black holes in detail, by thinking about gravity under fairly simple circumstances. Suppose that you are standing on the surface of a planet.

You throw a rock-and-roll dead on target up into the air. Assuming you dont throw it too hard, it will start for a while, but eventually the acceleration due to the planets gravity will make it start to fall down again. If you threw the rock hard enough, though, you could make it escape the planets gravity entirely. It would keep on rising forever.
