Seized and preserved appropriate investments (8)
I believe the answer is:
captured
'seized' is the definition.
('capture' can be a synonym of 'seize')
'preserved appropriate investments' is the wordplay.
I cannot really see how this works, but
'appropriate' could be 'apt' (synonyms) and 'apt' is located in the answer.
'preserved' could be 'cured' (similar in meaning) and 'cured' is present in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for captured that I've seen before include "Took prisoner" , "Caught, seized after a chase" , "Prisoners" , "Arrested, seized" , "Apprehended" .)
