Continuation of child support (11)
I believe the answer is:
maintenance
This might be a double definition.
'continuation' is the first definition.
(thesaurus)
'child support' is the second definition.
'maintenance' can be an answer for 'support' (maintenance is a kind of support). I am not sure about the 'child' bit.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for maintenance that I've seen before include "Care, conservation" , "bread and butter" , "Keep" , "Upkeep" , "What's done to preserve" .)
