Morphology

interspinous = spinous (transparent) = inter + spin + ous

Formed by adding the prefix 'inter-' ('between') to the adjectival base 'spinous' ('relating to the spine'), yielding a clear anatomical meaning 'between spines'.

Etymology

Interspinous combines the prefix inter- ('between') and spine ('backbone'), so it literally means 'between spines'. It describes something that sits in the small space between the bony spines on the bones of the spine, which is why doctors use the term for devices or pain in that area.
