means A territory or region governed as a division of a country, or figuratively, a sphere of responsibility or expertise that belongs to someone or something in particular.

from From Latin 'provincia,' the term Rome used for a territory under its control, governed by a Roman official. Its own roots are murky — possibly linked to 'pro' (on behalf of) plus a root related to 'vincere' (to conquer), though that connection is debated among etymologists rather than settled fact. What's certain is the Roman sense of a conquered or administered land outside the capital, which gave us both the geographic meaning (a province as a governed region) and the figurative one (a 'province' as someone's rightful domain of authority — the thing that is, so to speak, theirs to conquer or oversee).
