Morphology

sacral + nerve

The meaning 'any nerve from the sacral region' is directly and compositionally derived from 'sacral' (pertaining to the sacrum) + 'nerve' (a bundle of nerve fibers). This anatomical adjective+noun pattern is literal and cross-linguistically common (e.g. Spanish 'nervio sacro'), so a learner who knows both constituents will understand the MWE.

Etymology

Sacral nerve comes from the bone at the base of the spine called the sacrum, which people long ago called 'sacred'. The nerves near that bone were named sacral nerves, so sacral nerve means a spinal nerve from the lower spine that sends signals to the pelvis and legs.
