### Solving the Riddle: A Test of Wit

Riddles challenge our intellect, creativity, and ability to think outside the box. They celebrate our cognitive skills and offer a satisfying mental workout when solved.

One classic riddle asks:
**“What word begins and ends with ‘E,’ contains only one letter, yet is not the letter ‘E’ itself?”**

#### Breaking It Down:
1. **Starts and Ends with ‘E’:** This narrows the options to words with a specific structure.
2. **Contains Only One Letter:** At first glance, this seems paradoxical. However, interpreting “letter” as a *physical letter* (the kind you mail) offers a new perspective.
3. **Not the Letter ‘E’:** Rules out any direct association with the alphabetic letter ‘E.’

#### The Solution:
The answer is **“envelope.”**
– It begins and ends with the letter “E.”
– It contains one letter — the letter it holds inside.
– It isn’t the letter “E” itself.

This riddle showcases the joy of wordplay and the clever use of language’s dual meanings. It reminds us to embrace the unexpected, consider alternative interpretations, and delight in solving puzzles that challenge our thinking.
