The name 'Grizzly' or 'gray' was, according to the 

 Century Dictionary, given to this Bear on account of "its 

 usual colouration." The word 'grisly' (grewsome, grim, or 

 terrible) was applied later.

 thickset carnivorous animals of dull colours, not spotted or

 hind-feet are plantigrade; they have fixed claws; very short 

 tails; short, rounded ears, and the true molars with broad, flat 

 tuberculated crown.
