Prophet from Australia upset critic? (9)
I believe the answer is:
zoroaster
'prophet' is the definition.
(Zoroaster is an example)
'australia upset critic?' is the wordplay.
'australia' becomes 'oz' (informal name for Australia).
'upset' says the letters should be written in reverse.
'critic?' becomes 'roaster' (I can't justify this - if you can you should believe this answer much more).
'oz' in reverse letter order is 'zo'.
'zo'+'roaster'='ZOROASTER'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for zoroaster that I've seen before include "Persian prophet" , "Religious leader" .)
