What does "stanza" mean in a poem with letter options like this: abab aabb abac abcb

It means like the line of the poem that rhymes so, like

There is a place where the sidewalk ends

And before the street begins,

And there the grass grows soft and white,

And there the sun burns crimson bright,

And there the moon-bird rests from his flight

To cool in the peppermint wind.

Something like that!

Hope that helped!
