What is the best definition of a stanza break?

In poetry, a stanza break is a point in the poem where one stanza ends and another begins. Stanzas are groups of lines that are separated from each other by line breaks. The number of lines in a stanza can vary, but most stanzas contain between four and eight lines.

Stanzas are often used to create a sense of rhythm and structure in a poem. They can also be used to emphasize important ideas or to create dramatic effects. For example, a poet might use a stanza break to mark a shift in time or to introduce a new character.

Here is an example of a stanza break in the poem "The Raven" by Edgar Allan Poe:

> Once upon a midnight dreary, while I pondered, weak and weary,

Over many a quaint and curious volume of forgotten lore,

While I nodded, nearly napping, suddenly there came a tapping,

As of some one gently rapping, rapping at my chamber door.

" 'Tis some visitor," I muttered, "tapping at my chamber door —

Only this, and nothing more."

In this example, the stanza break occurs after the fourth line. This stanza break creates a sense of anticipation and suspense, as the reader is left wondering who is knocking at the speaker's door.
