What is the name of the poetic form introduced by Pushkin in 'Eugene Onegin'?

The poetic form introduced and popularized by Alexander Pushkin in “Eugene Onegin” is the Onegin stanza. It is also sometimes called the Pushkin sonnet, although it differs from conventional sonnet forms in structure and rhyme.

Each Onegin stanza contains fourteen lines, usually written in iambic tetrameter. Its distinctive rhyme pattern is aBaBccDDeFFeGG, combining alternating, paired, and interlocking rhymes. The capital and lowercase letters traditionally distinguish masculine and feminine endings in the Russian original.

Pushkin wrote “Eugene Onegin” between 1825 and 1832, publishing it serially before the complete edition appeared in 1833. The form is closely associated with the novel’s narrator, conversational tone, digressions, and shifts between comedy and emotional seriousness. It later influenced writers beyond Russia, including Vladimir Nabokov and Vikram Seth, whose novel “The Golden Gate” is written entirely in Onegin stanzas.
