Greek Alphabet Reference

Find a Greek letter by name, form, or position

This reference lists the 24 letters in the conventional alphabetic order, showing capital and lowercase characters alongside the English name, pronunciation guide, and examples of familiar symbol uses. Type a letter name, a Greek character, an order number, or a word in the use notes to narrow the table. Copy either character form when you need to paste it into notes, a document, or an equation.

Uppercase and lowercase forms can look quite different: compare Α and α, or Σ and σ. Lowercase sigma also has a word-final form, ς, in Greek writing; the table's standard lowercase character is σ. A character's appearance can vary by font, but Unicode assigns distinct character identities so text can be stored and exchanged consistently.

Pronunciation hints are approximate English reading aids. Greek letter names and sounds depend on whether you are learning modern Greek, ancient Greek, or reading a technical symbol aloud. A symbol's meaning also depends on its subject and context: for example, π may denote the mathematical constant in one setting, while other fields use the same letter differently.

Filter the table and copy a form

1. Search with any visible clue

   Enter an English letter name, its symbol, its sequence number, or a term appearing in the usage column. Clear the field to restore the full list.

2. Compare capital and lowercase

   Check the two character columns before copying. This matters when a formula distinguishes, for example, uppercase delta (Δ) from lowercase delta (δ).

3. Copy the character you need

   Use the copy control beside the capital or lowercase symbol, then paste it into the destination app and confirm its font displays the glyph.

Questions about forms and pronunciation

Use pronunciation and examples as clues

The pronunciation column is not audio instruction or a substitute for a Greek-language course. Usage notes are examples rather than authoritative definitions for every discipline. When entering a symbol into code, equations, or specialized material, confirm the intended character and meaning in that context.
