the.com/reappointment

means The formal act of being reinstated or reconfirmed in a position, office, or role one already held.

from Straightforward Latin-via-French carpentry: the prefix 're-' ('again') bolted onto 'appoint,' from Old French apointer, 'to arrange, settle, put in order' — itself from the phrase à point, 'to the point.' So an appointment was originally a settling-of-things, and a reappointment is simply that settling done a second time, formalizing what everyone already assumed was settled.
