It should be disbanded before it comes to light (5)
I believe the answer is:
cigar
This clue could be a double definition.
'it should be disbanded before it' is the first definition.
The definition suggests a singular noun which matches the answer.
'light' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'comes to' acts as a link.
Can you help me to learn more?
(Other definitions for cigar that I've seen before include "Smoked item" , "Havana, perhaps" , "Roll of cured tobacco" , "A real smoke!" , "Big roll of tobacco" .)
