Morphology
articulatio + trochoidea
This is a technical Latin/Greek anatomical term: while 'articulatio' (joint) signals a bone joint, the second element 'trochoidea' is not a common English word and its rotational sense (from Greek trochos 'wheel') is not accessible to a B1 learner. Because one constituent is specialized/unknown and the overall meaning (a pivot joint allowing rotation) depends on that specialized element, the expression is not transparently derivable from the provided parts.
Etymology
Articulatio trochoidea comes from Latin words: articulatio means 'joint' and trochoidea means 'wheel-like' or 'turning'. Imagine a wheel turning on a peg — that picture explains why the name describes a joint that only turns, like the pivot between the two forearm bones.
