Person from Houston (5)
I believe the answer is:
texan
'person from houston' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for texan that I've seen before include "Person from Austin, USA?" , "Inhabitant of Dallas?" , "Eg, native of Dallas" , "Person from southwestern US state" , "One from SW USA" .)
