Leave a state (3)
I believe the answer is:
goa
'state' is the definition.
(Indian state)
'leave a' is the wordplay.
'leave' becomes 'go'.
'go'+'a'='GOA'
(Other definitions for goa that I've seen before include "Indian island state" , "West coast Indian state" , "Indian Territory" , "stately annexation of India" , "Indian holiday destination" .)
