Morphology
This is a straightforward compositional noun phrase: 'trigeminal' specifies which nerve and 'nerve' names the anatomical structure, so together they directly denote the cranial nerve responsible for facial sensation. Although technical, the meaning follows standard anatomical naming conventions and is derivable from the constituents for a learner who knows both words.
Etymology
Trigeminal nerve comes from tri- meaning 'three' because the nerve splits into three main branches across the face. These branches carry feeling and help with chewing, so the name reminds us that this one nerve controls three big face areas and explains why damage causes numbness or pain.
