Feeling of being under a cloud? (5)
I believe the answer is:
gloom
'a cloud?' is the definition.
(thesaurus)
'feeling of being under' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is present in the answer.
The remaining letters 'glom' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for gloom that I've seen before include "Dimness" , "Partial darkness" , "Dark depression?" , "Murk" , "Darkness; depression" .)
