Symploce

Symploce is when you use two words, an old one and a new one, together for emphasis. It is like the saying, "old but gold!" Symploce is when an old word that has been around for a long time (like "old") is used together with a new word (like "gold"). You put them together like this to make it sound important and emphasize the idea. It's like saying, "Old but gold! It's still valuable and important even if it is old!"
