Study
Etymology
曝 combines 日 (sun) with 暴, which likely contributes both sound and the idea of exposing or laying open. The character suggests exposing something to sunlight.
Meaning mnemonic
The sun 日 on the left shines on the right side 暴, like laying something out in the open under strong sunlight to bleach or air it.
Reading mnemonic
For バク, imagine bleaching a white cloth in the sun and then backing away: back -> バク, as you leave the cloth exposed to the light.
