Spooner's N. American diving bird may glow in the dark (9)
I believe the answer is:
moonlight
'glow in the dark' is the definition.
The answer and definition can be both types of natural phenomena as well as being singular nouns.
Maybe there's a link between them I don't understand?
'spooner's n american diving bird' is the wordplay.
I cannot really understand how this works, but
'n' is within the answer.
'bird' could be 'oo' and 'oo' is present in the answer.
This explanation may well be incorrect...
'may' acts as a link.
Can you help me to learn more?
(Other definitions for moonlight that I've seen before include "Steerer of boat" , "Beethoven sonata" , "Beethoven's Op. twenty seven/two sonata" , "Perform work at night" , "work illegally" .)
