Hidden away? Discharged! (8)
I believe the answer is:
secreted
This might be a double definition.
'hidden away?' is the first definition.
(I've seen this in another clue)
'discharged' is the second definition.
The definition and answer can be both related to bodily activities as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for secreted that I've seen before include "Covered" , "Placed out of sight" , "Hid away" , "Hidden" .)
