No red dresses within limits of Tashkent (7)
I believe the answer is:
tsarist
'no red' is the definition.
Although both the answer and definition are adjectives, I don't understand how one could define the other.
'dresses within limits of tashkent' is the wordplay.
'dresses' becomes 'saris' (sari is a kind of dress).
'within' is an insertion indicator.
'limits of' means to remove the middle letters.
'tashkent' with its middle removed is 'tt'.
'saris' put inside 'tt' is 'TSARIST'.
Can you help me to learn more?
(Other definitions for tsarist that I've seen before include "Artists (anag.); supporter of Russian emperor" , "Russian emperor's supporter" , "Russian monarchist" , "Russian royal supporter" , "One supporting ruler" .)
