Haiku: A form of Japanese poetry, composed of seventeen syllables in a 5/7/5 pattern. The haiku evokes a complete impression or mood through the juxtaposition of a natural physical element such as a sound or sight, with a phrase to suggest a season or emotion. It developed from the nonstandard linked verse (haikai no renga) popular in the 16th and 17th centuries—the “opening verse” (hokku) of which eventually was treated as in independent form, known today as haiku. Its greatest practitioner was Matsuo Basho, followed by the painter Yosa Buson, Kobayashi Issa, and Masaoka Shiki. Haiku’s emphasis on the immediate and concrete influenced early 20th century Imagism in Europe and America, especially through the influence of Ezra Pound.
Two well-known examples by Basho are the ‘summer grasses’ verse composed on a visit to the site where Yoshitsune was vanquished, and the following:
Furuike ya An ancient pond—
Kawazu tobikomu Then the sound of water
Mizu no oto Where a frog plops in”
