Preserve from trouble (6)
I believe the answer is:
pickle
This clue could be a double definition.
'preserve' is the first definition.
(I know that pickle is a more specific form of the action preserve)
'trouble' is the second definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'from' is the link.
Can you help me to learn more?
(Other definitions for pickle that I've seen before include "Solution for preserving food" , "Relish; preserve" , "Jam - vegetables preserved in vinegar or brine" , "Preserve; muddle" , "A preserve or an informal predicament" .)
