Question

What are figures of speech used by the poet of the poem brook?

Answer 1

1) For men may come and men may go => refrain(repetition of phrase)
2) I slip- I slide, I gloom- I glance=>alliteration(repetition of letters)
3) I babble=> onometapoiea(sounding words or phrases)
4) I babble on the pebbles=>Imagery (Imagery is the name given to the  elements in a poem that spark off the senses. Despite "image" being a  synonym for "picture", images need not be only visual; any of the five  senses (sight, hearing, touch, taste, smell) can respond to what  a poet writes. metaphors and similies also come in imagery)
5) I make the nettled sunbeam dance=> personification ( when something  that is not human is given human characteristics.
