Maybe Afghan father shot crook (6)
I believe the answer is:
pashto
'maybe afghan' is the definition.
'pashto' can be an answer for 'afghan' (I've seen this before). I am not sure about the 'maybe' bit.
'father shot crook' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'crook' indicates an anagram (a crooked version of the letters).
'shot' is an anagram of 'shto'.
'pa'+'shto'='PASHTO'
Can you help me to learn more?
(Other definitions for pashto that I've seen before include "Iranian language spoken in Afghanistan and Pakistan" , "language follows!" , "hear this from Afghanistan" , "Afghan" .)
