Medical problem for a seaside resort (7)
I believe the answer is:
disease
'medical problem' is the definition.
The definition and answer can be both states of affairs as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'seaside resort' is the wordplay.
'resort' indicates an anagram (re-sort the letters).
'seaside' is an anagram of 'DISEASE'.
'for a' is the link.
Can you help me to learn more?
(Other definitions for disease that I've seen before include "Sickness" , "Illness, malady" , "Impairment of health" , "scrapie for example" , "blight" .)
