Concern after study’s expanding outwards? (6)
I believe the answer is:
convex
'expanding outwards?' is the definition.
I can't judge whether this defines the answer.
'concern after study's' is the wordplay.
'concern' becomes 'vex' (I can't justify this - if you can you should believe this answer much more).
'after' means one lot of letters go next to another.
'study' becomes 'con' (con can informally mean to study).
'vex' after 'con' is 'CONVEX'.
Can you help me to learn more?
(Other definitions for convex that I've seen before include "Curved like surface of a ball" , "Curving outwards" , "Curving outward" , "Rounded on the outside" , "Curving like surface of ball" .)
