Cyst formed scab at three points (7)
I believe the answer is:
abscess
'cyst' is the definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'formed scab at three points' is the wordplay.
'formed' indicates an anagram.
'at' is a charade indicator (letters next to each other).
'three points' becomes 'ess' (I can't justify this - if you can you should believe this answer much more).
'scab' anagrammed gives 'absc'.
'absc'+'ess'='ABSCESS'
Can you help me to learn more?
(Other definitions for abscess that I've seen before include "BSE's sac? (anag)" , "Gathering of pus in cavity" , "Inflamed swelling" , "Pus-filled swelling" , "Swollen area in tissue" .)
