How do 'denizens' and 'chivalric' add to our understanding of the tigers' attitude?
Tigers like all beasts of prey are the 'denizens' of the forest. They live far away from human settlements. They are called 'chivalric'. This shows the majestic and honourable position that they occupy in the world of animals. So the use of 'denizens' and 'chivalric' for tigers add to our understanding of their attitude.
