plural abysses. Learner's definition of ABYSS. [count] : a hole so deep or a space so great that it cannot be measured. the ocean's abysses. I stood at the edge of the cliff and gazed down into the yawning/gaping abyss. [=chasm]
An abyss is a very deep hole or pit. So falling into an abyss literally means falling down a very deep hole. Figuratively, then, it can mean getting into some problem that you can't get out of. The idea of falling and falling and never reaching the bottom can also be frightening, so the phrase can be used to mean something scary.
