How it works

ε is the epsilon symbol: Greek small letter epsilon, U+03B5, the fifth letter of the Greek alphabet. The rows add the lunate form ϵ, the capital Ε, accented έ, math styles, and the membership sign ∈, which is not epsilon.

Read the full guide

\epsilon and \varepsilon are two shapes

ε, U+03B5, looks like a reversed 3. ϵ, U+03F5, is the lunate form, a half circle with a bar. In LaTeX \varepsilon prints ε and \epsilon prints ϵ. HTML names them the other way around: ε is ε, and ϵ is ϵ.

Epsilon is the Greek letter for e

Epsilon writes the vowel e. Its capital Ε is drawn like a Latin E but is its own character, U+0395. ∈, the sign for is an element of, evolved from epsilon and is a third character, U+2208.

ɛ, the Latin open e of phonetic writing, is U+025B, one more character with the same look.
϶, the reversed form, is an old logic sign for such that.

Questions and answers

What is the Alt code for epsilon?

Alt+238 types the small ε. Keep Alt down, type 238 on the number pad with Num Lock on, and release. The capital Ε and the lunate ϵ have no Alt code.

What does the epsilon letter stand for?

Small ε stands for an arbitrarily small positive quantity in calculus, for the permittivity of a medium in physics, written ε₀ for free space, and for strain in engineering. It is the Greek alphabet's fifth letter.

Is ∈ an epsilon?

No. ∈ is the element-of sign, U+2208, ∈ in HTML and \in in LaTeX. Its shape evolved from epsilon: the sign began as a short form of the Latin word est, which means is.

How do you say epsilon?

English says EP-sih-lon, with the stress on the first syllable. Greek writes the name έψιλον.

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 epsilon is for, as https://en.wikipedia.org/wiki/Epsilon records it: the fifth letter, the numeral value five, the two shapes of the small letter (the reversed 3 and the lunate form), the capital that is identical to the Latin E, the Latin epsilon of phonetic writing, the membership sign that evolved from epsilon and the backward epsilon for such that, the arbitrarily small quantity, permittivity and its value for free space, strain, the dual numbers, the first name of the letter, and the Latin and Cyrillic letters that arose from epsilon. The tonos as the accent of modern Greek: https://en.wikipedia.org/wiki/Greek_diacritics. 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 letter and its capital, the lunate and the reversed lunate symbol, the two forms with the tonos, the fifteen math alphabet forms, the Latin, Coptic and Cyrillic letters, three membership signs it is mistaken for, and this site's own strings of two to four characters, each written the way the article writes it. Left out: the sixteen accented epsilons of older Greek spelling, the other Greek letters (each has its own page), the other set signs, which the math signs page has, and the script and other styled forms of the Latin E.
