Red spots in green cabbage coming up (4)
I believe the answer is:
acne
'red spots' is the definition.
'acne' can be an answer for 'spots' (I've seen this before). I'm not sure about the 'red' bit.
'in green cabbage coming up' is the wordplay.
'in' says the answer is hidden in the clue.
'coming up' says the letters should be written in reverse.
'enca' is hidden within 'green cabbage'.
'enca' backwards is 'ACNE'.
Can you help me to learn more?
(Other definitions for acne that I've seen before include "Skin disorder" , "Pimply ailment of adolescnce" , "Skin affliction" , "Face problems" , "Youthful problem" .)
