vers libre

vers libre, (French: “free verse”), 19th-century poetic innovation that liberated French poetry from its traditional prosodic rules. In vers libre, the basic metrical unit is the phrase rather than a line of a fixed number of syllables, as was traditional in French versification since the Middle Ages. In vers libre, the lengths of lines may vary according to the sense of the poem, the complete sentence replaces the stanza as a unit of meaning, and rhyme is optional.

Vers libre appears to have been the independent invention of several different French poets in the late 1880s. Among its early advocates and theoreticians were Gustave Kahn, Jules Laforgue, Francis Vielé-Griffin, and Édouard Dujardin. The use of a free prosodic structure in French poetry was not entirely new: it had antecedents in the poems of the Symbolists, the prose poems of Rimbaud, and, much earlier, in the metrical experiments of Victor Hugo. But the widespread adoption of vers libre at the end of the 19th century influenced poetic trends in other countries, so that verse patterned on irregular metrical designs has become a tradition in the modern poetry of all Western nations.
