Which word best illustrates the mood of the poem?
nothing gold can stay
by robert frost
nature's first green is gold
her hardest hue to hold
her early leafs a flower
but only so an hour
then leaf subsides to leaf
so eden sank to grief
so dawn goes down to day
nothing gold can stay

impermanence

Explanation:

The excerpt talks about subsiding and how some things can't "stay" for some reason which is depicted in earlier lines.

I'm making a assumption that the poem intends that, nothing gold can stay. like a leaf eventually will die and a tree will wither away and the sun will turn into the moon, basically nothing stays the same, eventually time will go forward and things will change. makes sense?
