Morphology

shelf + bracket

The meaning is directly and compositionally derived from 'shelf' (a horizontal board) + 'bracket' (a support): a support for a shelf. This noun–noun compound follows a common and cross‑linguistic pattern, so a B1 learner who knows both words would readily understand the MWE.

Etymology

The name shelf bracket gives a clear picture: the bracket is a metal or wooden arm fixed to the wall that holds a shelf up. So it means 'a support fixed to a wall to hold up a shelf'.
