This country sounds like one in a hurry (6)
I believe the answer is:
russia
'this country' is the definition.
(Russia is a country)
'sounds like one in a hurry' is the wordplay.
'sounds like' shows a homophone (sound like).
'one in a hurry' becomes 'rusher' (I've seen this in another clue).
'rusher' sounds like 'RUSSIA'.
(Other definitions for russia that I've seen before include "Country of the tsars" , "Former Communist country of eastern Europe and northern Asia" , "East European state" , "Moscow's country" , "A leather" .)
