✨ Understanding Psi (Ψ)
🔤 How Do You Pronounce Psi?

📜 The Greek Alphabet in Context
To give you a better idea of where Psi sits, here’s the tail end of the Greek alphabet:
| Greek Letter | Uppercase | Lowercase |
|---|---|---|
| Phi | Φ | φ |
| Chi | Χ | χ |
| Psi | Ψ | ψ |
| Omega | Ω | ω |

🏛️ Fun Fact: Why Do People Say “Alpha and Omega”?
The phrase “Alpha and Omega” is a popular idiom that means “the beginning and the end.” It has Biblical origins, used to describe God as eternal — existing from the very start (Alpha) to the very end (Omega).
But just because Omega is last doesn’t mean Psi isn’t important. In many ways, Psi is the penultimate symbol of something significant — one step before the end.

Fraternities and sororities often use Greek letters for their names.
