A shed can be a dark place (5)
I believe the answer is:
hades
'a dark place' is the definition.
'hades' can be an answer for 'place' (I have seen 'gloomy place' mean 'hades' so perhaps 'place' could also mean 'hades'). I'm unsure of the 'a dark' bit.
'a shed can be' is the wordplay.
'can be' is an anagram indicator.
'a'+'shed'='ashed'
'ashed' with letters rearranged gives 'HADES'.
Can you help me to learn more?
(Other definitions for hades that I've seen before include "It's hell in the Greek shade" , "Inferno" , "gloomy place" , "The underworld where the souls of the dead live" , "Hell of Greek myth" .)
