Morphology

nervus + ischiadicus

This is a specialized Latin anatomical name: while 'nervus' signals 'nerve', the second element ('ischiadicus') is technical and undefined here, and its relation to the sciatic region (ischium) is not transparent to a B1 learner. Because the term is specialist Latin morphology rather than everyday English composition, the overall meaning 'sciatic nerve' cannot be reliably derived from the parts by typical learners.

Etymology

Nervus ischiadicus comes from Latin: nervus means 'nerve' and ischiadicus points to the hip bone called the 'ischium'. Because this large nerve starts near the hip and runs down the leg, the name explains why we now call it the 'sciatic nerve'.
