What is a Stanza in a Poem?

In poetry, a stanza is a group of lines that form a unit within a poem. It's like a paragraph in prose writing, and helps to organize the ideas and structure of the poem. Stanzas can vary in length and can contain any number of lines. For example, a quatrain has four lines, while a couplet has two. The length and pattern of stanzas can greatly impact the rhythm and flow of the poem. Understanding stanzas is important for analyzing and appreciating the structure of poems.
