Why “rehallow” is a great word
To make a thing holy again after its sanctity has been lost or violated. From the English prefix re- ("again") + hallow ("to make holy, sanctify"), first attested in 1632. Unlike "consecrate," which implies an inaugural blessing of the profane, or "desecrate," its violent opposite, to rehallow is an act of solemn repair. It is the careful scrubbing of soot from a vandalized altar, the whispered prayer in a battlefield chapel long used as a barn, and the patient restoration of a name spoken only in curses to one spoken again in grace—a quiet, stubborn belief that what was once sacred can be made so a second time.
