Morphology

blot + out

There is a clear link to the constituents: 'blot' (to mark or cover) plus the particle 'out' yields a sense of covering/obscuring or removing completely. However, the extension to erasing from sight or memory is somewhat metaphorical and the exact sense (especially 'erase from memory') may not be fully predictable to a B1 learner, so it is only partially transparent.

Etymology

Blot out comes from the image of a dark blot spreading out over a page and hiding the words or picture. So, to blot out something today means 'to make it impossible to see, read, or remember'.
