A padre's unusual in displays of force (7)
I believe the answer is:
parades
'displays of force' is the definition.
'parades' can be an answer for 'displays' (parade is a kind of display). I am not certain of the 'of force' bit.
'a padre's unusual in' is the wordplay.
'unusual' is an anagram indicator.
'in' indicates putting letters inside.
'padres' anagrammed gives 'prades'.
'a' placed into 'prades' is 'PARADES'.
Can you help me to learn more?
(Other definitions for parades that I've seen before include "Displays" , "Cavalcades" .)
