Recommence showing some children points (5)
I believe the answer is:
renew
'recommence' is the definition.
(I've seen this before)
'some children points' is the wordplay.
'some' indicates the central letters.
'children' becomes 'wards' (ward can mean a child under someone's care).
'points' becomes 'enew' (I am not sure about this - if you are sure you should believe this answer much more).
The central letter of 'wards' is 'r'.
'r'+'enew'='RENEW'
'showing' acts as a link.
Can you help me to learn more?
(Other definitions for renew that I've seen before include "Reinforce" , "Establish again" , "Restore to original state" , "Extend eg library loan" , "make a fresh start" .)
