Morphology
trigeminal = trigeminus (semi-transparent) = tri + gemin + al
The prefix 'tri-' ('three') is clear, but the combining form 'gemin-' is an uncommon Latin medical combining form (not a standalone English word), so the overall meaning ('threefold' → used for the three-branched cranial nerve) is only partly transparent to general learners.
Etymology
Trigeminal comes from the Latin parts tri- ('three') and geminus ('twin'), and it describes things related to the nerve that has three branches in the face. So calling something trigeminal means it is 'about the three-part facial nerve'.
