Raising someone else's issue leads to Bill on right to choose (8)
I believe the answer is:
adoption
'raising someone else's issue leads' is the definition.
I can't tell whether this definition defines the answer.
'bill on right to choose' is the wordplay.
'bill' becomes 'ad' (advertisement stuck on wall).
'on' is a charade indicator (letters next to each other).
'right to choose' becomes 'option' (I've seen this before).
'ad'+'option'='ADOPTION'
'to' is the link.
Can you help me to learn more?
(Other definitions for adoption that I've seen before include "Legal process of taking a child into one's family" , "Acceptance (of, eg, a report)" , "means to increase size of family?" , "Taking on another's child as one's own" , "Taking-on, acceptance" .)
