Here are a few options that *almost* work:
* "Ah, a happy joy!" - This phrase expresses delight, and the beginning and end almost mirror each other.
* "Wow, so wow!" - This is more of a general expression of amazement, but it's a palindrome.
Ultimately, creating a perfect palindrome for "delight" would likely require a more creative and metaphorical approach. Perhaps something like:
* "A joyful, joyful A!" - This uses the "A" as a placeholder for a person or thing experiencing delight.
