To determine whether the expression

\[
\frac{36}{41} + \frac{\sqrt{3}}{3}
\]

represents a rational number or an irrational number, let's analyze each part of the expression.

1. **The number \(\frac{36}{41}\):**
   - This is a fraction where both the numerator (36) and the denominator (41) are integers, and the denominator is not zero.
   - Since any number that can be expressed as a fraction of two integers is a rational number, \(\frac{36}{41}\) is a **rational number**.

2. **The number \(\frac{\sqrt{3}}{3}\):**
   - The number \(\sqrt{3}\) is known to be an irrational number because it cannot be expressed as a fraction of two integers, and its decimal representation is non-terminating and non-repeating.
   - Dividing an irrational number (\(\sqrt{3}\)) by a non-zero integer (3) still results in an irrational number. Therefore, \(\frac{\sqrt{3}}{3}\) is an **irrational number**.

3. **Sum of a rational number and an irrational number:**
   - A fundamental property of rational and irrational numbers is that the sum of a rational number and an irrational number is always an irrational number.
   - Therefore, the sum \(\frac{36}{41} + \frac{\sqrt{3}}{3}\) will be an **irrational number**.

### Conclusion:

The sum 

\[
\frac{36}{41} + \frac{\sqrt{3}}{3}
\]

represents **an irrational number**.

- This is because the number \(\frac{36}{41}\) is a **rational number**.
- And the number \(\frac{\sqrt{3}}{3}\) is an **irrational number**.
- The sum of a rational number and an irrational number is an **irrational number**.
