pentadecasyllable
A pentadecasyllable is a line of verse containing fifteen syllables. This meter is relatively uncommon in English poetry compared to shorter or longer forms. While not as widely recognized as the iambic pentameter, for example, it can be found in various poetic traditions and experiments. The structure of a pentadecasyllable can be achieved through different rhythmic patterns, and its length offers a substantial canvas for descriptive language or extended thought within a single line. Poets might employ pentadecasyllables to create a sense of flow, build complex imagery, or achieve a particular sonic effect. Its use is often a deliberate choice to deviate from more standard metrical feet and contribute to the unique character of a poem. The precise arrangement of stressed and unstressed syllables within a pentadecasyllable can vary significantly, making it a flexible, albeit less frequently utilized, poetic device.
