Child care originally introduced in Israel (5)
I believe the answer is:
scion
'child' is the definition.
(thesaurus)
'care originally introduced in israel' is the wordplay.
'originally' suggests taking the first letters.
'introduced in' indicates putting letters inside.
'israel' becomes 'sion' (I've seen this in other clues).
The initial letter of 'care' is 'c'.
'c' placed into 'sion' is 'SCION'.
(Other definitions for scion that I've seen before include "Descendant - heir" , "Young shoot or twig" , "Descendent - heir" , "Issue" , "Young shoot/twig" .)
