Greek Alphabet: All 24 Letters, Names and Symbols (Α–Ω)

The Greek alphabet has 24 letters, from alpha (Α, α) to omega (Ω, ω). Each has uppercase and lowercase forms. Greek letters appear in the Greek language, mathematics, physics, chemistry, engineering, and statistics. This reference lists all 24 names and their correct characters, so you can recognize or copy the symbol you need.

Complete list of 24 Greek alphabet letters

Some uppercase Greek letters look exactly like familiar Latin letters—for example, capital alpha Α looks like Latin A—but they are different Unicode characters. The table uses actual Greek letters rather than replacing them with Latin lookalikes.

Copy and paste uppercase and lowercase Greek letters

Uppercase: Α Β Γ Δ Ε Ζ Η Θ Ι Κ Λ Μ Ν Ξ Ο Π Ρ Σ Τ Υ Φ Χ Ψ Ω

Lowercase: α β γ δ ε ζ η θ ι κ λ μ ν ξ ο π ρ σ τ υ φ χ ψ ω

There is also a lowercase final sigma (ς), used at the end of many Greek words. The usual lowercase sigma is σ; these are different forms of the same Greek letter, not separate letters in the 24-letter alphabet.

Where Greek letters are commonly used

Mathematics: π (pi) often denotes a mathematical constant, Σ (capital sigma) denotes summation, and Δ (capital delta) commonly represents a change or difference. Statistics: μ (mu) often represents a population mean and σ (sigma) a population standard deviation. Physics: λ (lambda) can represent wavelength, and Ω (omega) is used as the symbol for ohms. The meanings depend on context and notation.

How to insert Greek letters in Microsoft Word

In Word for Windows, type a letter’s Unicode hexadecimal code, then press Alt + X; for example, 03C0 converts to π and 03A9 converts to Ω. Alternatively, choose Insert > Symbol > More Symbols and browse the Greek and Coptic group. In a Word equation, supported Math AutoCorrect commands such as \alpha followed by Space can insert symbols.
