Deem deliberate (8)
I believe the answer is:
consider
I believe this is a double definition.
'deem' is the first definition.
(I know that deem is a more specific form of the action consider)
'deliberate' is the second definition.
(I know that deliberate can be written as consider)
(Other definitions for consider that I've seen before include "Contemplate" , "Think about, reflect upon" , "Think about - judge" , "Take into account" , "Deem to be, believe" .)
