Father dear, change procession (6)
I believe the answer is:
parade
'procession' is the definition.
(I know that parade is a type of procession)
'father dear change' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'change' indicates an anagram.
'dear' with letters rearranged gives 'rade'.
'pa'+'rade'='PARADE'
(Other definitions for parade that I've seen before include "Ostentation" , "Row of shops, march" , "Flaunt; ceremonial march" , "Air - display" , "Cavalcade or procession" .)
