Morphology

spinal + canal

The meaning is directly derivable from 'spinal' (relating to the spine) combined with 'canal' (a passage), so together they denote the passage in the spine through which the spinal cord runs. This is a straightforward noun–noun compositional pattern that is cross-linguistically common, making it immediately comprehensible to learners who know both constituents.

Etymology

The noun spinal canal comes from a simple picture: the spine is a column of bones with a long canal or 'passage' through its centre where the 'spinal cord' runs. So spinal canal means the protected space inside the spine that holds the 'spinal cord' and keeps it safe.
