(In one sense the marked words are an extreme example of exact rhyme, but that's not the term that best describes them.)
He sat in a wheeled chair, waiting for dark,
And shivered in his ghastly suit of grey,
Legless, sewn short at elbow. Through the park
Voices of boys rang saddening like a hymn,
Voices of play and pleasure after day,
Till gathering sleep had mothered them from him.
--Wilfred Owen
