Hybrid car has its big release (9)
I believe the answer is:
catharsis
'big release' is the definition.
'catharsis' can be an answer for 'release' (I've seen this before). I am unsure of the 'big' bit.
'hybrid car has its' is the wordplay.
'hybrid' is an anagram indicator (I've seen this in other clues).
'car'+'has'+'its'='carhasits'
'carhasits' with letters rearranged gives 'CATHARSIS'.
Can you help me to learn more?
(Other definitions for catharsis that I've seen before include "The release of pent-up emotions" , "cleansing'" , "relief of tensions" , "Process of releasing pent-up emotions" , "Emotional purge" .)
