Very gloomy-looking judge hoovering up line (5)
I believe the answer is:
bleak
'very gloomy' is the definition.
'bleak' can be an answer for 'gloomy' (bleak means gloomy or sad). I am not certain of the 'very' bit.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for bleak that I've seen before include "''... House'' (Dickens)" , "Cold and raw" , "Bare, inhospitable" , "Cold and unwelcoming" , "Exposed to the elements" .)
