Repetition & Refrain
Anadiplosis
The last word of one clause becomes the first word of the next, linking them like a chain. The sequence feels like one thing leading to another. Stacked with rising importance, it becomes gradatio (climax).
"Fear leads to anger. Anger leads to hate. Hate leads to suffering." — Yoda
Don't confuse it with Epanalepsis. Gradatio is anadiplosis sustained up a ladder of intensity; epanalepsis circles back within a single clause.
