This sentence is a palindrome, a group of words that is the same when you read it forwards from the beginning or backwards from the end. It is very hard to compose one of these, and most of them don’t make a lot of sense. Here are a few more famous palindromes in Spanish:
La ruta natural
Se van sus naves
La ruta nos aportó otro paso natural
Dábale arroz a la zorra el abad
Anita lava la tina
Do you think you could compose one?
