Texas or Ukraine city (6)
I believe the answer is:
odessa
'texas or ukraine city' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for odessa that I've seen before include "Ukrainian location" , "Ukrainian naval base" , "Black Sea location" , "Battleship Potemkin mutiny port" , "Do seas come into Ukrainian city?" .)
