How it works

ζ is the zeta symbol: Greek small letter zeta, U+03B6, the sixth letter of the Greek alphabet. The rows add the capital Ζ, math styles such as 𝜁, the strings ζ(s), ζ(2) and ζ(3), and the look-alikes ξ and ς.

Read the full guide

ζ is not ξ or ς

These three small Greek letters all end in a tail below the line. ζ is zeta, U+03B6. ξ is xi, U+03BE. ς is the sigma that ends a word, U+03C2. Each has its own HTML name and LaTeX macro: ζ and \zeta, ξ and \xi, &sigmaf; and \varsigma.

Sixth letter, numeral seven

Zeta is the Greek alphabet's sixth letter but stands for 7 as a numeral, because the old letter digamma once held sixth place.

Without a package LaTeX has \zeta and no \Zeta, the capital that looks like a Latin Z.
ζ(2) answers the Basel problem, and ζ(3) is Apéry's constant.

Questions and answers

How do I type the zeta symbol?

No Alt code types zeta, so copying is the short way. In HTML ζ is the small letter and Ζ the capital, ζ and Ζ as numbers. In LaTeX \zeta prints ζ in math mode.

What does the letter zeta stand for?

Small ζ names the Riemann zeta function, written ζ(s), and an oscillating system's damping ratio. In modern Greek it writes the sound z. Zed, the British name of the letter Z, comes from the word zeta.

How do you say zeta?

British English says zee-ta and American English zay-ta. Modern Greek says zee-ta and writes the name ζήτα.

How this list was compiled: Names, and the code points they belong to, are from UnicodeData.txt, version 18.0.0 (https://www.unicode.org/Public/18.0.0/ucd/UnicodeData.txt), printed in sentence case; its decomposition field is what says a math alphabet character is a plain letter in a font, or that an accented letter is a letter plus its marks. Aliases, notes and cross-references are from NamesList.txt of the same version (https://www.unicode.org/Public/18.0.0/ucd/NamesList.txt), the version a character was added in is from DerivedAge.txt (https://www.unicode.org/Public/18.0.0/ucd/DerivedAge.txt), and the years are from https://www.unicode.org/history/publicationdates.html. Alt codes are from the code page 437 table (https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/PC/CP437.TXT). HTML entity names are from https://html.spec.whatwg.org/entities.json, the shortest standard name first. LaTeX macros are listed only when LaTeX's own fontdef.dtx (https://github.com/latex3/latex2e/tree/develop/base) declares them, matched to a code point through unicode-math-table.tex (https://github.com/latex3/unicode-math). A cell is empty where no such method exists. What zeta is for, as https://en.wikipedia.org/wiki/Zeta records it: the sixth letter, the numeral value 7 and the digamma that explains it, the sound z, the Riemann zeta function, the damping ratio, the capital that is not used because it looks like Z, the name zed, the names of the letter in Greek, the sigma delta of some early poets, the two English ways of saying the name, and the Latin Z and Cyrillic ze that arose from zeta. The zeta function, its value at 2 and the Basel problem, and its value at 3, Apéry's constant: https://en.wikipedia.org/wiki/Riemann_zeta_function. The Coptic alphabet as a descendant of the Greek one, given code points of its own in Unicode 4.1: https://en.wikipedia.org/wiki/Greek_alphabet. Listed: the two letters, the ten math alphabet forms, the Coptic and Cyrillic letters, four characters it is mistaken for, and this site's own strings of two to four characters, each written the way a source writes it. Left out: the other Greek letters (xi and final sigma appear once each, as look-alikes), the forms of sigma, which the sigma page has, and a letter of Ugaritic that only shares the name.
