Morphology

tibialis + posterior

The term is transparently compositional: 'tibialis' denotes a muscle involved in foot movement and 'posterior' indicates its rear/behind location, so together they denote the posterior muscle of the lower leg that supports the arch. This follows standard anatomical naming conventions (common across languages) and would be inferable by a B1 learner who knows both constituent meanings.

Etymology

Tibialis posterior comes from old Latin: tibialis means 'of the shin' and posterior means 'back'. This gives a clear image of a muscle sitting behind the shin that helps move the foot and support the arch.
