The word 'stratification' is built upon the Latin root stratum, meaning a spread-out layer, which itself derives from the Proto-Indo-European root stere- meaning 'to spread'. Combined with the formative element -ficare (to make) and the abstract noun suffix -ation, the term literally means 'the process of making into layers'. This concrete geological concept of forming successive strata was later extended metaphorically to describe the structured layering of social classes, where society is seen as composed of superimposed hierarchical groups. The logic of the word elegantly connects the physical act of depositing material in sheets to the sociological process of systematic ranking and division.
