Part of what Persians dislike now... (2,7)
I believe the answer is:
at present
'now' is the definition.
(synonyms)
'part of what persians dislike' is the wordplay.
I cannot quite see how this works, but
an anagram of 'part' is 'atpr' which is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for at present that I've seen before include "temporarily" , "these days" , "Nowadays" , "As of now, during this time" , "Currently, right now" .)
