Repetition & Refrain
Symploce
Combining anaphora and epistrophe: successive clauses repeat both their opening and closing words. The fixed wording draws attention to what changes in the middle.
"When there is talk of hatred, let us stand up and talk against it. When there is talk of violence, let us stand up and talk against it." — Bill Clinton
Don't confuse it with Parallelism. Not mere parallelism: symploce requires the identical words at both edges, not just matching grammar.
Examples
If we lose our homes, we will rebuild. If we lose our roads, we will rebuild.
Both clauses begin “If we lose our” and end “we will rebuild”; the middle changes.
