Morphology

block + out

The meaning is directly compositional: 'block' in the sense of obstruct or stop combined with the directional/particle 'out' yields 'prevent from entering or being noticed' (e.g., light or noise). This verb+particle pattern is a common, predictable English construction and would be understandable to a B1 learner who knows the constituent words.

Etymology

Block out The verb block out paints a simple picture: you put curtains or a board to block the light out so it cannot come into a room. That's why it means 'to prevent light, sound, or air from entering'.
