If a prelude and an interlude why there epilude?

You're right to think that! It's a natural progression of thought. Here's why there's no "epilude":

* "Prelude" means "before the play," "before the song," or "before the main event."

* "Interlude" means "between the parts" or "between the acts" of a play, performance, or story.

The idea behind a prelude and interlude is to set the stage, transition the audience, or provide additional context. An "epilude" would logically mean "after the main event." However, this concept doesn't really exist in the same way:

* The ending is the ending. There's no need to add something on afterward to further explain or transition. The ending is where we're left to contemplate the story or performance.

* Epilogue: There's already a term for "after the main event," and that's an epilogue. An epilogue can provide additional information about the characters, their fates, or the world after the story's events.

So, instead of an "epilude," we have an epilogue. 😊
