Spots city maze complex (6)
I believe the answer is:
eczema
'spots city maze complex' is the definition.
I can't tell whether this definition defines the answer.
'city maze complex' is the wordplay.
'city' becomes 'EC' (the City of London postcode).
'complex' indicates an anagram.
'maze' is an anagram of 'zema'.
'ec'+'zema'='ECZEMA'
Can you help me to learn more?
(Other definitions for eczema that I've seen before include "Irritating disease of the skin" , "Distressing skin ailment" , "Itchy skin disorder" , "Inflammatory skin disorder" , "Pimply condition as of adolescence" .)
