The noun 'stratum' derives its etymology from the Latin word 'stratum,' which means a bed or layer. This term evolved from the past participle of the verb 'sternere,' which means 'to spread or lay out.' In the context of organization or categorization, 'stratum' metaphorically refers to a distinct level or class, much like layers in a geological or architectural sense, illustrating the historical connection between the word's meaning and its Latin origin.
