Recommence showing points to some of the children (5)
I believe the answer is:
renew
'recommence' is the definition.
(I've seen this before)
'showing points to some of the children' is the wordplay.
'showing points' becomes 'enew' (I can't justify this - if you can you should believe this answer much more).
'to' means one lot of letters go next to another (I've seen this in other clues).
'some of' says to take the centre (I've seen 'some' mean this).
'the children' becomes 'Jrs' (Jr is an example).
The centre of 'jrs' is 'r'.
'enew' after 'r' is 'RENEW'.
Can you help me to learn more?
(Other definitions for renew that I've seen before include "Replace" , "Extend (subscription)" , "Start afresh" , "Reform" , "Reinforce" .)
