Grizzly, for instance (4)
I believe the answer is:
bear
'grizzly for instance' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bear that I've seen before include "Pessimistic investor" , "Harbour - transport" , "Give birth to; animal" , "Support; brutish person" , "Carry; large animal" .)
