Polyptoton

Polyptoton is the repetition of a word's root in a different grammatical form within the same passage, as in 'the judged were judging', so the echo is heard as deliberate.

She had not been warned, and now she was the warning.

Warned and warning share a root and differ in form, and the shift is the point: the sentence turns a thing that happened to her into a thing she has become. That transformation is what polyptoton (pronounced pol-ip-TOE-ton) does, and no other figure does it as compactly.

Polyptoton examples

Shakespeare's Sonnet 116 uses it twice in two lines: Love is not love / Which alters when it alteration finds, / Or bends with the remover to remove. Why it works: alters and alteration, remover and remove make the argument sound like a definition, as if love is being tested against its own words.

More, in plain prose:

• He judged nobody, and was judged by everybody. Why it works: active becomes passive, and the reversal is the character's life.
• The rules had rules. Why it works: three words, and the bureaucracy is complete.
• Nothing about the settlement settled anything. Why it works: the noun promises something the verb denies.

Polyptoton vs an accidental echo

It is worth putting next to mirror words, which are the same repetition committed by accident: she decided to make a decision. The difference is not how often it happens but whether it is meant, and the reader can tell. A deliberate polyptoton falls on a stressed position in the sentence and does visible work. An accidental echo sits in an unremarkable spot and simply chimes.

If you are unsure which one you have written, move the repetition to the end of the sentence. If it earns the position, keep it; if it does not, it was an echo, and one of the words should go.

Where it fits

It sits naturally inside antithesis, since a contrast between two forms of one word is about as tight as a contrast can get. It also pairs with anadiplosis, where the word that ends one clause can return in a new form to start the next.

Common mistakes

• Wordplay for its own sake. If the change of form does not change the meaning, the line is a pun without a joke.
• Too many in one passage. One polyptoton is a sharp line. Three in a paragraph sounds like a riddle.

Frequently asked questions

What is polyptoton in simple terms?

Polyptoton is using the same root word twice in different forms close together, such as 'warned' and 'warning', or 'judge' and 'judged'. The change of form is what gives the line its meaning.

How do you pronounce polyptoton?

It is pronounced pol-ip-TOE-ton. The name comes from Greek and refers to the many grammatical forms a word can take.

What is the difference between polyptoton and anthimeria?

Anthimeria uses a word unchanged as a different part of speech, as in 'she elbowed past'. Polyptoton changes the word's form, as in 'alters' and 'alteration', and repeats it.
