I would like to gather ideas for neologisms covering spatial positional/relational adjectives, which are rather sparsely attested, and often cause a headache for NQ writers. These are adjectives that specify an objects position with regards to a center point, axis, or plane.
I am thinking of this set, listing the attested words:
medial/middle/central: endea, en(t)ya
external/exterior: ava, ette
inferior/nether: EQ úva
