Men getting out of manhole with divine head light (4)
I believe the answer is:
halo
'light' is the definition.
(halo is a kind of light)
'men getting out of manhole with divine head' is the wordplay.
I cannot really see how this works, but
'of' could be 'o' and 'o' is located in the answer.
The remaining letters 'hal' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for halo that I've seen before include "Angelic aura" , "Circle painted over saint's head" , "Ring of saintliness" , "Nimbus" , "Band of light" .)
