Firm staging? (3)
I believe the answer is:
set
This clue might be a double definition.
'firm' is the first definition.
(I've seen this before)
'staging?' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
Can you help me to learn more?
(Other definitions for set that I've seen before include "(Of the sun) drop below the horizon" , "Become fixed or solid" , "Mount (gem); scenery" , "Ancient god" , "declined" .)
