Father gets part freedom (6)
I believe the answer is:
parole
'freedom' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'father gets part' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'gets' says to put letters next to each other.
'part' becomes 'role' (eg a theatrical role).
'pa'+'role'='PAROLE'
Can you help me to learn more?
(Other definitions for parole that I've seen before include "Word - condition of liberty" , "(One's) word" , "Conditionally release" , "limited release" , "Give Al rope when he's released early" .)
