Question

“Higher still and higher/From the earth thou springest…”
“O wild West Wind, thou breath of Autumn’s being…”
“Like a Poet hidden/In the light of thought…”

Answer 1

"O wild West Wind, thou breath of Autumn’s being…" is the most clear example of apostrophe, as it directly addresses the wind as if it were a person or thing capable of understanding and responding.
