Banged-up Mini dopes launched across river (10)
I believe the answer is:
imprisoned
'banged-up' is the definition.
I can't tell whether this definition defines the answer.
'mini dopes launched across river' is the wordplay.
'launched' indicates an anagram.
'across' means one lot of letters goes inside another.
'river' becomes 'r' (abbreviation for river).
'mini'+'dopes'='minidopes'
'minidopes' with letters rearranged gives 'impisoned'.
'impisoned' enclosing 'r' is 'IMPRISONED'.
Can you help me to learn more?
(Other definitions for imprisoned that I've seen before include "behind bars" , "Locked up" , "in jail" , "Put away" .)
