Rude and bad-tempered, a bit like a grizzly? (7)
I believe the answer is:
bearish
'like a grizzly?' is the definition.
(I've seen this in another clue)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bearish that I've seen before include "Like each part of 18 [POOH]" , "but not at all like a bull" , "Expecting losses" , "Clumsy" , "anticipating fall in prices" .)
