Concern raised about verse getting split (5,2)
I believe the answer is:
carve up
'split' is the definition.
(I know that split can be written as carve up)
'concern raised about verse' is the wordplay.
'concern' becomes 'care' (synonyms).
'raised' becomes 'up' (similar in meaning).
'about' indicates putting letters inside.
'verse' becomes 'v'.
'care'+'up'='careup'
'careup' placed around 'v' is 'CARVE-UP'.
'getting' acts as a link.
(Other definitions for carve up that I've seen before include "Sharing out of the spoils" , "Knife" , "Aggressively pass" , "Unfair distribution" , "unwarranted division?" .)
