Spook essentially embracing German punk movement (4)
I believe the answer is:
pogo
'punk movement' is the definition.
(I've seen this before)
'spook essentially embracing german' is the wordplay.
'essentially' indicates the central letters.
'embracing' indicates putting letters inside.
'german' becomes 'g' (abbreviation).
The centre of 'spook' is 'poo'.
'poo' placed around 'g' is 'POGO'.
(Other definitions for pogo that I've seen before include "punk dancing" , "Punk movement" , "jump up and down" , "-- stick" , "gets jumped on by children" .)
