A converb phrase is a grammatical construction employing verb forms that function adverbially, expressing actions subordinate to or occurring simultaneously with the main verb. In poetic contexts, converb phrases allow for the compact expression of temporal, causal, or modal relationships between actions, creating fluid connections between events or states. This construction, more common in some languages than English, enables poets to layer multiple actions within single clauses, achieving syntactic efficiency and dynamic representation of complex sequences or concurrent phenomena.

A Converb phrase uses verb forms that function adverbially (common in Turkic or Mongolic languages)—in English poetry, may mimic this through participial or gerund constructions for fluid action.
