Plant transporting meat is shown (8)
I believe the answer is:
revealed
'is shown' is the definition.
(I've seen this before)
'plant transporting meat' is the wordplay.
I cannot quite understand how this works, but
'meat' could be 'veal' (veal is a kind of meat) and 'veal' is found in the answer.
'plant' could be 'reed' (reed is a kind of plant) and 'reed' is found within the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for revealed that I've seen before include "Made known to others" , "Like the religion" , "Shown" , "'Made known, disclosed (8)'" , "Exposed" .)
