Tomas Transtromer, a Swedish poet who won the Nobel Prize in Literature in 2011 for a body of work known for shrewd metaphors couched in deceptively spare language, crystalline descriptions of natural beauty and explorations of the mysteries of identity and creativity, died on Thursday in Stockholm. He was 83.
The Swedish publisher Albert Bonniers announced the death without giving a cause. In 1990, at age 59, Mr. Transtromer had a stroke that severely curtailed his ability to speak; he also lost the use of his right arm.
With a pared-down style and brusque, forthright diction, Mr. Transtromer (pronounced TRAWN-stroh-mur) wrote in accessible language, though often in the service of ideas that were diaphanous and not easy to parse; he could be precisely observant one moment and veer toward surrealism the next.
