Leave with a gazelle (3)
I believe the answer is:
goa
'gazelle' is the definition.
(I've seen this before)
'leave with a' is the wordplay.
'leave' becomes 'go'.
'with' means one lot of letters go next to another.
'go'+'a'='GOA'
(Other definitions for goa that I've seen before include "Former Portuguese colony on India's west coast" , "Part of West India" , "Indian W. coast state" , "gazelle?" , "Suitable place in India" .)
