Morphology

symphysion = symphysis (opaque) = symphysis + on

Formally derived from the medical noun 'symphysis' with the classical nominal ending '-on'; the relation is clear in form but the suffix is a classical/technical marker not productive in everyday English.

Etymology

Symphysion comes from Greek parts syn- 'together' and physis 'growth', so it literally means a place where parts 'grow together'. That's why the symphysion is the front point of the lower jaw where the two halves meet and is used as a simple reference in anatomy and dentistry.
