I'm a little stuck... Click here to teach me more about this clue!

'keep' is the definition.
(I know that keep can be written as preserve)

I can't explain the remainder of the clue.

(Other definitions for preserve that I've seen before include "Particular interest" , "area where game is held" , "Keep - pickle - store" , "Prevent from deteriorating" , "Prevent from rotting" .)

I've seen this clue in The Daily Express.
