Greek letters

Alpha, beta, gamma

Greek letters are the characters of the Greek alphabet, from alpha to omega.

In academic and scientific contexts, they serve as symbols for variables, constants, and concepts: pi represents the ratio of a circle's circumference to its diameter, sigma denotes standard deviation.

Fraternities and sororities take names from Greek letter combinations: Delta Gamma, Phi Beta Kappa.

Someone doesn't know their Greek letters if they lack basic academic knowledge.
