Bear, for one (6)
I believe the answer is:
animal
'bear for one' is the definition.
(bear is a kind of animal)
This is the entire clue.
(Other definitions for animal that I've seen before include "I''m Alan (anag) - a wild, crazy person" , "' - - Farm', Orwell" , "Brutish sort" , "It shares the world with vegetable and mineral" , "something in the zoo?" .)
