Male said to be affected in unusual way? (5)
I believe the answer is:
midas
'unusual way?' is the definition.
The definition suggests a singular noun which matches the answer.
'male said to be affected in' is the wordplay.
'male' becomes 'm' (common abbreviation).
'to be affected' indicates anagramming the letters.
'in' is an insertion indicator.
'said' anagrammed gives 'idas'.
'm' inserted within 'idas' is 'MIDAS'.
Can you help me to learn more?
(Other definitions for midas that I've seen before include "Golden-touch king" , "Legendary king who could turn everything to gold" , "I'm sad (anag) -- king of Phrygia" , "Greek mythological king with money-making touch" , "old king" .)
