King ordered a chair from city (7)
I believe the answer is:
karachi
'city' is the definition.
(I have seen 'Pakistani city' mean 'karachi' so perhaps 'city' could also mean 'karachi')
'king ordered a chair' is the wordplay.
'king' becomes 'K' (abbreviation for king in chess).
'ordered' indicates anagramming the letters.
'a'+'chair'='achair'
'achair' is an anagram of 'arachi'.
'k'+'arachi'='KARACHI'
'from' acts as a link.
(Other definitions for karachi that I've seen before include "Pakistan's first capital" , "City/port of Pakistan" , "Asian city" , "Pakistani metropolis" , "Major city of Pakistan" .)
