Well, Sapphic stanza is a kind of poetry that is named after Sappho, who was a Greek poetess from a long, long time ago. She was really good at writing poems about love and beauty.
In this type of poetry, there are four lines in each stanza. The first three lines are longer than the fourth, and they rhyme with each other, which means that they sound similar at the end of the line. The fourth line is shorter and doesn't rhyme with the others.
In Polish poetry, writers use the Sapphic stanza to create beautiful poems about love, nature, and other important things. This type of poetry can be hard to write because you need to make sure the lines all sound good together and they have the right number of syllables. But when done well, it can be really amazing!
