Medicine's supposed to suppress frigidity (7)
I believe the answer is:
iciness
'frigidity' is the definition.
(I've seen this before)
'medicine's supposed to suppress' is the wordplay.
'ICINESS' is hidden within the letters.
But, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for iciness that I've seen before include "Hostility, unfriendliness" , "Frigidity" , "Extreme hostility" , "unfriendly manner" , "Extreme cold" .)
