Hidden moths may come to this (5)
I believe the answer is:
light
'hidden moths may come to this' is the definition.
The definition suggests a singular noun which matches the answer.
This is the entire clue.
Can you help me to learn more?
(Other definitions for light that I've seen before include "Window; insubstantial" , "What smoker may be requesting" , "Airy; luminescence" , "Radiance" , "Torch" .)
