A poem consisting of 14 lines written in iambic pentameter is called what?

A poem consisting of 14 lines written in iambic pentameter is specifically called a sonnet. Sonnets are structured works that often explore themes of love, nature, or philosophy. The form has specific characteristics, including the use of iambic pentameter, which is a metrical line made up of five feet with each foot containing an unstressed syllable followed by a stressed syllable.

There are different types of sonnets, such as the Shakespearean (or English) sonnet and the Petrarchan (or Italian) sonnet, both adhering to this 14-line structure. This unique combination of form and meter is what distinguishes a sonnet from other types of poetry.

In contrast, a ballad typically tells a story and is often written in shorter stanzas, while a stanza refers to a grouped set of lines in a poem but does not denote a specific form like the sonnet. A haiku is a short form of Japanese poetry consisting of three lines with a syllable pattern of 5-7-5, which is also distinct from the 14-line structure of a sonnet.
