Relating to bears (6)
I believe the answer is:
ursine
'relating to bears' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ursine that I've seen before include "Like Paddington" , "Describing Pooh or Yogi?" , "like a character in 14 across [=>BEAR]" , "Relating to bears" , "Bearlike" .)
