The 80-year-old is best known for his breakthrough work 17 dikter (17 poems), written when he was a young man in 1954. Critics have praised his use of metaphor and economy of words.
"He has a fantastic ability with metaphors, but not just in a sort of technical sense. But he has the ability to find metaphors, details, that can make an entire situation or a thing or a feeling very very understandable," Englund tells Radio Sweden.
Englund describes how Tranströmer treats the image of an oak tree in mid-winter in one of his poems, saying, "the greenery will erupt from the bottles of the oak."
"It's a wonderful image, how the greenery will pop out, like from champagne – from a bottle," says Englund, adding that it has made an indelible impression on the way he looks at winter landscapes.
While not known to be a prolific writer, Tranströmer's work has been translated into 60 languages, including English; one collection entitled A Half-Finished Heaven.
Tranströmer suffered a stroke in 1990, which has made him largely unable to speak. However, he has continued to publish work.
It is nearly 40 years since a Swede has won this prize.
