Morphology
This is a straightforward adjective + noun composition: 'hypoglossal' denotes the tongue-related (twelfth cranial) nerve and 'nerve' names a neural fiber tract, so together they specify the nerve that serves the tongue. Although the term is technical, its meaning is directly derivable from the known constituents, so a learner who knows both words will understand it.
Etymology
Hypoglossal nerve comes from Greek parts hypo meaning 'under' and glossal meaning 'tongue'. The nerve runs under the tongue to move it, so the name means the nerve that controls the tongue.
