Why Is Sir Gawain Called The Green Knight

Sir Gawain
In the story Sir Gawain and the Green Knight, Gawain displays his good conduct, like bravery and courage.
Gawain proved he was brave because he overcame several obstacles, like the temptation of the host’s wife, who was very attractive. Another obstacle was the Green Knight.
