Stoat-like animal (6)
I believe the answer is:
weasel
'stoat-like animal' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for weasel that I've seen before include "These sort of words are meaningless" , "Boggle" , "Animal; sly person" , "Carnivore -- saw eel (anag)" , "Carnivore; a sly person" .)
