Morphology

spinal + accessory

The parts 'spinal' (relating to the vertebral column) and 'accessory' (auxiliary) give a learner a loose, compositional sense—an auxiliary structure related to the spine—but they do not specifically indicate 'the eleventh cranial nerve' or even that the item is a nerve. Because this is a technical anatomical term that requires domain knowledge to recover the precise referent, it is partially but not fully predictable to a B1 learner.

Etymology

The noun spinal accessory is the name for a 'nerve' that has parts coming from the spinal cord and from the head, so the word accessory shows it is an extra link between them. That's why spinal accessory refers to the nerve that helps the neck and shoulder muscles move.
