Eft (4)
I believe the answer is:
newt
'eft' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for newt that I've seen before include "The epitome of drunkenness" , "Went to find kind of water lizard" , "Garden-pond amphibian" , "found in pond!" , "Amphibian - a Ken Livingstone pet?" .)
