Identify the kind of this poem and its implicit and explicit devices:
Whose woods these are I think I know.
His house is in the village, though;
He will not see me stopping here
To watch his woods fill up with snow.
My little horse must think it queer
To stop without a farmhouse near
Between the woods and frozen lake
The darkest evening of the year.
He gives his harness bells a shake
To ask if there is some mistake.
The only other sound’s the sweep
Of easy wind and downy flake.
The woods are lovely, dark and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.
It is not simple to exactly say what type of poem is this though its rhyme scheme and stanzas are almost the same. The same goes for its devices as there are many devices at work such as the woods could be a symbol or a metaphor. Please ask a single question in one-go to get clear and precise answer.
