To decorate something again or in a new way, typically a room or building.
From 'decorate' with the prefix 're-' meaning 'again.' Decorate itself comes from Latin 'decorare' meaning 'to adorn.' This compound form emerged as interior design became common.
The 're-' prefix is a time-traveler's tool—it suggests that something was good enough to do again, and redecorating is one of the few ways people regularly remake their personal spaces!
