Show a padre out (6)
I believe the answer is:
parade
'show' is the definition.
(I know that parade is a type of showing)
'a padre out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'a'+'padre'='apadre'
'apadre' anagrammed gives 'PARADE'.
(Other definitions for parade that I've seen before include "Exhibit" , "Flaunt; ceremonial march" , "Easter ___ , 1948 film with Judy Garland and Fred Astaire" , "Carnival" , "March-past of troops etc." .)
