Disliked concealing dry bananas with added water (8)
I believe the answer is:
hydrated
'added water' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Perhaps you can see an association between them that I don't see?
'disliked concealing dry bananas' is the wordplay.
'disliked' becomes 'hated' (hating is a kind of disliking).
'concealing' indicates putting letters inside.
'bananas' is an anagram indicator (informal term for mad).
'dry' with letters rearranged gives 'ydr'.
'hated' enclosing 'ydr' is 'HYDRATED'.
'with' is the link.
Can you help me to learn more?
(Other definitions for hydrated that I've seen before include "so after a drink" , "Watery" .)
