All to give a child a name (5)
I believe the answer is:
total
'all' is the definition.
(thesaurus)
'give a child a name' is the wordplay.
'give' is a charade indicator (letters next to each other).
'a child' becomes 'tot' (term for a young child).
'a name' becomes 'al' ().
'tot'+'al' is 'TOTAL'.
'to' is the link.
(Other definitions for total that I've seen before include "given by 8 [ADDING MACHINES]" , "final answer" , "Reckon" , "The whole, sum" , "Comprising the whole" .)
