The form gained distinction early in the Tokugawa period (1603–1867) when the great master Bashō elevated the hokku to a highly refined and conscious art. Originally, the haiku form was restricted in subject matter to an objective description of nature suggestive of one of the seasons, evoking a definite, though unstated, emotional response.

Today the term haiku is used to describe all poems that use the three-line 17-syllable structure, even the earlier hokku. The hokku (often interchangeably called haikai) became known as the haiku late in the 19th century, when it was entirely divested of its original function of opening a sequence of verse. The hokku, which set the tone of a renga, had to mention in its three lines such subjects as the season, time of day, and the dominant features of the landscape, making it almost an independent poem. The term haiku is derived from the first element of the word haikai (a humorous form of renga, or linked-verse poem) and the second element of the word hokku (the initial stanza of a renga). The haiku first emerged in Japanese literature during the 17th century, as a terse reaction to elaborate poetic traditions, though it did not become known by the name haiku until the 19th century. Haiku, unrhymed poetic form consisting of 17 syllables arranged in three lines of 5, 7, and 5 syllables respectively.
