What is a single row of words in a poem known as?

A single row of words in a poem is referred to as a line. This term specifically describes one horizontal arrangement of text within the poem. Lines are fundamental components of poetry, as they contribute to the poem's structure, rhythm, and overall meaning. Each line can evoke emotion and imagery, and the way lines are arranged can significantly impact a reader's experience of the poem.

The term "stanza" refers to a group of lines forming a distinct section of a poem, while "verse" can sometimes be used interchangeably with line in common parlance but is more accurately associated with metrical composition or the broader poem structure. "Dialogue," on the other hand, pertains to conversations between characters and is not a relevant term in the context of poetry.
