the.com/commissioner

means An official formally charged with overseeing a specific department, function, or body, and answerable for how it's run.

from Traces to Latin 'committere' — to entrust, connect, or commit — via 'commissio,' meaning a sending or entrusting of authority. The 'commission' was originally the document or warrant handing someone a specific duty; the 'commissioner' was simply whoever held that warrant. The word entered English through medieval administrative and legal Latin, carrying the same core idea ever since: power delegated downward, with accountability expected to flow back up.
