Returned for money and more sand, maybe (8)
I believe the answer is:
ransomed
'returned for money' is the definition.
The answer and definition can be both to do with ownership as well as being past participle verbs.
Perhaps there's a link between them I don't understand?
'more sand maybe' is the wordplay.
'maybe' is an anagram indicator.
'more'+'sand'='moresand'
'moresand' is an anagram of 'RANSOMED'.
'and' is the link.
Can you help me to learn more?
(Other definitions for ransomed that I've seen before include "held hostage for money" , "rescued" , "Bought ones freedom" , "sequel to Kidnapped?" , "Paid for" .)
