The reason is quite simple: there are only so many symbols in the Greek and Latin alphabets, and scientists and mathematicians generally do not use symbols from other languages. Epsilon (έψιλον) is the fifth letter of the Greek alphabet and it is written as Ε in uppercase and ε in lowercase. It also contains ASCII codes, both HTML character references (decimals) and entity references (symbolic names) if available. from Jeff Miller's Earliest Uses of Various Mathematical Symbols:. The epsilon is used in the epsilon-delta definition of the limit. Despite its pronunciation as mid, in the International Phonetic Alphabet, the Latin epsilon /ɛ/ represents open-mid front unrounded vowel, as in the English word pet /pɛt/. There is one more similar term and that is epsilon which is denoted by ε. Epsilon is the unit of the permittivity of an insulating, or dielectric material. (See section 3.3 for biographical information about Levi-Civita.) Epsilon (uppercase Ε, lowercase ε or lunate ϵ; Greek: Έψιλον) is the fifth letter of the Greek alphabet, corresponding phonetically to a mid front unrounded vowel /e/. As per convention, Carroll defines the Levi-Civita symbol $\tilde{\epsilon}_{\mu_1 \mu_2 \dots \mu_n}$ as the sign of the permutation of $01\dots(n-1)$ on page 82. Symbols.com.
