Greek alphabet: every letter to copy
The Greek alphabet has been used for nearly 3,000 years. It is the alphabet of modern Greek, spoken by about 13 million people, and its letters are used every day in maths, science and engineering. This page lists all 24 letters in capital and small forms: Α α alpha, Β β beta, Γ γ gamma, Δ δ delta and so on to Ω ω omega, followed by accented letters, the final sigma ς and Greek symbols.

The 24 Greek letters
- Α α Β β Γ γ Δ δ: Alpha, beta, gamma, delta.

- Ι ι Κ κ Λ λ Μ μ: Iota, kappa, lambda, mu.
- Ν ν Ξ ξ Ο ο Π π: Nu, xi, omicron, pi.
- Ρ ρ Σ σ ς Τ τ Υ υ: Rho, sigma, tau, upsilon.
- Φ φ Χ χ Ψ ψ Ω ω: Phi, chi, psi, omega.
Greek letters in maths and science
Greek letters are the language of formulas. π (pi) is the circle constant, Δ (delta) means change, Σ (sigma) means sum, θ (theta) is an angle, λ (lambda) is wavelength, μ (mu) means micro, σ (sigma) is standard deviation, Ω (omega) is the unit of resistance and α, β and γ name angles and particles.

Final sigma and accents
The small letter sigma has two forms: σ in the middle of a word and ς at the end, as in λόγος. Modern Greek uses one accent mark called the tonos, as in ά έ ή ί ό ύ ώ, to show stress. Older and religious texts use more marks, called polytonic Greek. The accented letters on this page let you spell Greek words correctly.
Greek letters in everyday life
You see Greek letters in many places: fraternity and sorority names, brand names, the Olympic flame, and words like alphabet, which comes from alpha and beta. Writers use Ω as a symbol of the end, and designers like Greek letters for logos and patterns.
Look-alike letters
Some Greek capitals look exactly like Latin letters, such as Α, Β, Ε, Η, Ι, Κ, Μ, Ν, Ο, Ρ, Τ, Χ and Υ. They are different characters, though, so searching or spell-checking can behave differently. Use Greek letters only in Greek text and formulas, and normal letters for English words.
Typing Greek
Every major system includes a Greek keyboard. For maths, many editors also accept names like \alpha in LaTeX. For a quick letter in a document or chat, copying from here is the simplest way.
