Leave Indian elephant's tail (3,2)
I believe the answer is:
hop it
'leave' is the definition.
(I've seen this before)
'indian elephant's tail' is the wordplay.
'indian' becomes 'hopi' (Hopi is an example).
'tail' suggests the final letters.
The last letter of 'elephant' is 't'.
'hopi'+'t'='HOP IT'
(Other definitions for hop it that I've seen before include "Skedaddle!" , "Push off!" , "Go away (colloq.)" , "Run along now!" , "Get away!" .)
