Misery in igloo, maybe (5)
I believe the answer is:
gloom
'misery' is the definition.
(I've seen this before)
'in igloo maybe' is the wordplay.
'in' says the answer is hidden in the clue.
'GLOOM' is hidden within 'igloo maybe'.
(Other definitions for gloom that I've seen before include "Dark depression?" , "Murkiness" , "Melancholy state" , "Near-darkness - misery" , "Obscurity or melancholy" .)
