An amount of freedom in a temporary master (8)
I believe the answer is:
dominate
'master' is the definition.
(I know that master can be written as dominate)
'an amount of freedom in a temporary' is the wordplay.
'an amount of' indicates the answer is hidden within the clue (a certain amount of the clue).
'DOMINATE' can be found hidden inside 'freedom in a temporary'.
(Other definitions for dominate that I've seen before include "corner" , "Tower over" , "Be lord over" , "Rule" , "Govern" .)
