Put on the ground, perhaps, as specified (4,4)
I believe the answer is:
laid down
'specified' is the definition.
(I've seen this before)
'put on the ground perhaps' is the wordplay.
'put' becomes 'laid' (I've seen this in another clue).
'on' is a charade indicator (letters next to each other).
'the ground perhaps' becomes 'down' (I am not sure about this - if you are sure you should believe this answer much more).
'laid'+'down'='LAID DOWN'
'as' is the link.
Can you help me to learn more?
(Other definitions for laid down that I've seen before include "Ordained" , "Insisted upon - abandoned" , "specified" , "Stipulated - deposited" .)
