Meat in grass no longer hidden (8)
I believe the answer is:
revealed
'no longer hidden' is the definition.
The definition and answer can be both to do with perception as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'meat in grass' is the wordplay.
'meat' becomes 'veal' (veal is a kind of meat).
'in' is an insertion indicator.
'grass' becomes 'reed' (type of grass plant).
'veal' put into 'reed' is 'REVEALED'.
Can you help me to learn more?
(Other definitions for revealed that I've seen before include "Made known to others" , "Like the religion" , "Discovered" , "'Made known, disclosed (8)'" , "Made clear and visible" .)
