Solution is a single noun.
Combined clue:
- Eloquent appeal for repose
This is my own
I think this clues the word...
RESTORATION. An 'oration' is an eloquent or ceremonial speech, and 'rest' is a synonym of 'repose'. Thus if it were the subject of an 'eloquent appeal' you might call such a speech a rest oration...
This fits the title too:
'Restoration' means 'returning something to its former state or quality', i.e. making it great again!
