protero-/hystero-

I was wondering:

if hysterodynamic nouns were actually composed of two nouns, namely
a combining form + a proterodynamic noun, we could merge
proterodynamic and hysterodynamic into one type.

ex. in the family relationshp nouns

*pax-ter

*-ter appears as a suffix in the most varied contexts, and as -tar
('inhabitant of') in Basque and Iberian. Was it once a noun?
