A padre prepared for a public procession (6)
I believe the answer is:
parade
'a public procession' is the definition.
(I've seen this before)
'a padre prepared' is the wordplay.
'prepared' indicates an anagram.
'a'+'padre'='apadre'
'apadre' is an anagram of 'PARADE'.
'for' is the link.
(Other definitions for parade that I've seen before include "Organised procession of displays, performances, etc" , "Carnival" , "Ostentation" , "Easter ___ , 1948 film with Judy Garland and Fred Astaire" , "Air - display" .)
