### Step-by-Step Solution:

1. **Understanding the Structure of the Litchi Fruit**:
- The litchi fruit has several components, including the pericarp, which is the outer layer of the fruit. The pericarp consists of three layers: the epicarp, mesocarp, and endocarp.

4. **Characteristics of the Aril**:
- The aril is fleshy and juicy, which makes it appealing and palatable. It is considered the third integument of the seed, providing a sweet and edible portion of the fruit.

5. **Conclusion**:
- Therefore, the edible part of the litchi fruit is the aril, which is a collar-like outgrowth from the base of the ovule.
