Miserable dwelling in East Sussex resort, large (5)
I believe the answer is:
hovel
'miserable dwelling' is the definition.
(I've seen this in another clue)
'resort large' is the wordplay.
'resort' becomes 'Hove' (seaside resort).
'large' becomes 'L' (eg in clothes sizes).
'hove'+'l'='HOVEL'
'in east sussex' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for hovel that I've seen before include "Small crude shelter" , "Shack" , "dump" , "Crude dwelling" , "Ramshackle dwelling" .)
