Animal turning to legendary city (7)
I believe the answer is:
camelot
'legendary city' is the definition.
'camelot' can be an answer for 'city' (I have seen 'Fabulous city' mean 'camelot' so perhaps 'city' could also mean 'camelot'). I'm not sure about the 'legendary' bit.
'animal turning to' is the wordplay.
'animal' becomes 'camel' (I've seen this before).
'turning' says the letters should be written backwards.
'to' reversed gives 'ot'.
'camel'+'ot'='CAMELOT'
Can you help me to learn more?
(Other definitions for camelot that I've seen before include "Mythical British kingdom" , "Location of King Arthur's court" , "Idyllic situation" , "King Arthur's capital" , "the Kennedy era" .)
