What Persian said without purpose the wrong way (5)
I believe the answer is:
miaow
'what persian said' is the definition.
I can't judge whether this defines the answer.
'without purpose the wrong way' is the wordplay.
'without' becomes 'wo' (abbreviation of 'without', normally with a slash).
'purpose' becomes 'aim' (synonyms).
'the wrong way' says the letters should be written backwards.
'wo'+'aim'='woaim'
'woaim' back-to-front is 'MIAOW'.
Can you help me to learn more?
(Other definitions for miaow that I've seen before include "Cry of a cat" , "Cat chat?" , "Cat call?" , "Feline sound" , "Beastly remark" .)
