Greek party trick uncovered (5)
I believe the answer is:
doric
'greek' is the definition.
(Doric is an example)
'party trick uncovered' is the wordplay.
'party' becomes 'do' (do is a kind of party).
'uncovered' says to take the centre.
The middle of 'trick' is 'ric'.
'do'+'ric'='DORIC'
(Other definitions for doric that I've seen before include "Greek dialect" , "Greek architectural style" , "Type of classical architecture" , "Architectural style of Ancient Greece" , "One of the Greek orders of architecture" .)
