Describes what is apparent in perverse sex (8)
I believe the answer is:
explains
'describes' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?
'apparent in perverse sex' is the wordplay.
'apparent' becomes 'plain' (synonyms).
'in' indicates putting letters inside.
'perverse' indicates anagramming the letters.
'sex' anagrammed gives 'exs'.
'plain' put within 'exs' is 'EXPLAINS'.
'what is' acts as a link.
Can you help me to learn more?
(Other definitions for explains that I've seen before include "Deciphers" , "Makes something clear" , "Breaks down" , "Spells out" , "Gives reasons for" .)
