Ghetto temporarily covering sign (5)
I believe the answer is:
totem
'sign' is the definition.
(I've seen this before)
'ghetto temporarily covering' is the wordplay.
'covering' says the answer is hidden in the clue.
'TOTEM' is hidden within 'ghetto temporarily'.
(Other definitions for totem that I've seen before include "Venerated object" , "Animal as clan symbol" , "Revered object" , "emblem of tribe?" , "Image representing tribe" .)
