the.com/inauguration

means The formal ceremony that marks the start of something official — most often a leader taking office, but also the opening of a building, institution, or era.

from From Latin inaugurare, 'to consecrate by augury' — to install someone (or something) only after the augurs, Rome's official bird-watchers, had read the omens. The root is augur, the priest who studied the flight, calls, and feeding of birds to decide whether the gods approved. So buried inside every inauguration is a Roman squinting at the sky, waiting for the right vulture to swing by before anyone could take the job.
