Question

I shall be telling this with a sigh

Somewhere ages and ages hence:
Two roads diverged in a wood, and I—
I took the one less traveled by,
And that has made all the difference.

Which figure of speech is used?

Answer 1

Metaphor: There are many metaphors in the poem like road, fork in the road, and yellowwoods. The road in the poem is a metaphor of life, while the fork metaphorically represents the choices we make to determine the course of our lives. Yellow woods is a metaphor of making decisions during a hard time in a persons life.
