Soldier intends to acquire personal wealth (7,5)
I believe the answer is:
private means
'acquire personal wealth' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'soldier intends' is the wordplay.
'soldier' becomes 'private' (private is a type of soldier).
'intends' becomes 'means' ('mean' can be a synonym of 'intend').
'private'+'means'='PRIVATE MEANS'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for private means that I've seen before include "source of income" , "make money from investments" , "Unearned income" , "Income other than salary" .)
