What does demarcating mean?
'Demarcating' is the present participle of the verb 'demarcate', meaning to fix or mark the boundaries or limits of something. The word operates both literally and figuratively. Literally, it describes the physical marking of a frontier, border, or plot of land — the work of surveyors and treaty commissions demarcating national boundaries. Figuratively, it describes drawing clear lines between ideas, roles, or domains, as when a policy document sets about demarcating the responsibilities of two government agencies. Because of this precision, 'demarcating' belongs chiefly to formal registers: law, diplomacy, administration, science, and academic prose. Its connotations are neutral and exacting — to demarcate is not merely to notice a difference but actively to establish where one thing ends and another begins. Derived from the Spanish 'demarcar', which itself traces back through Italian to Latin roots meaning to mark boundaries, it shares ancestry with 'margin' and 'mark'. A related noun, 'demarcation', names the boundary or division itself.

Etymology of demarcating
'Demarcating' derives from the verb 'demarcate', borrowed in the mid-17th century from Spanish 'demarcar', itself influenced by Italian 'demarcare'. These trace to the Latin 'marcare', from 'margo' ('boundary, edge'), the same root that gives English 'margin'. The word entered English amid European treaties and colonial charters, where fixing exact territorial limits made such precision vocabulary indispensable; its cognates include 'demarcation' and, more distantly, 'marque' as in 'letters of marque'.
