Satisfied about media boss being calmed down (7)
I believe the answer is:
sedated
'calmed down' is the definition.
'sedated' can be an answer for 'calmed' ('sedate' can be a synonym of 'calm'). I'm not certain of the 'down' bit.
'satisfied about media boss' is the wordplay.
'satisfied' becomes 'sated' (I've seen this before).
'about' is an insertion indicator.
'media boss' becomes 'ed' (short for editor).
'sated' going around 'ed' is 'SEDATED'.
'being' is the link.
Can you help me to learn more?
(Other definitions for sedated that I've seen before include "Given a tranquilliser" , "Calmed with drugs" , "Given calming drugs" , "Under the influence of drugs" , "Tranquillized" .)
