substrata
Layers lying beneath
Substrata is the plural of substratum—underlying layers or foundations.
In geology, substrata are the rock or soil layers beneath the surface.
The word extends to anything foundational: the cultural substrata of a society, the ideological substrata beneath political movements.
The text reveals substrata of meaning that reward close reading.
