Show poetry in the right circle (5)
I believe the answer is:
rodeo
'show' is the definition.
(rodeo is a kind of show)
'poetry in the right circle' is the wordplay.
'poetry' becomes 'ode' (I've seen this before).
'in the' indicates putting letters inside.
'right' becomes 'r' (common abbreviation).
'circle' becomes 'o'.
'r'+'o'='ro'
'ode' going inside 'ro' is 'RODEO'.
(Other definitions for rodeo that I've seen before include "Show with broncobusters" , "sort of exhibition" , "One should be up for this event" , "Originally, a round up of cattle" , "show with mounting excitement" .)
