Greek diacritics

Beta (uppercase Β, lowercase β, internal ϐ; Greek: Βήτα [ˈvita]; English pronunciation: /ˈbeɪtə/ (US); English pronunciation: /ˈbiːtə/ (UK)) is the second letter of the Greek alphabet. In the system of Greek numerals it has a value of 2. It was derived from the Phoenician letter Beth Beth. Letters that arose from Beta include the Roman B and the Cyrillic letters Б and В.

In high-quality print, a variant of the letter is sometimes used that does not have a descender except at the beginning of a word: βίβλος is written βίϐλος. Lowercase ϐ is very common in handwriting.



Ancient Greek

In Ancient Greek, Beta represented a 'b' and the name of the letter, βῆτα, was pronounced something like [ˈbɛːta]. The name of the letter in English derives from this; the American pronunciation is /ˈbeɪtə/, whereas the British pronunciation is /ˈbiːtə/. See: American and British English pronunciation differences.

Modern Greek

In Modern Greek, it represents a voiced labiodental fricative /v/ and the Modern Greek name of the letter, Βήτα, is /ˈvita/.

Use as a symbol or name

Beta is often used to denote a variable in mathematics and physics, where it often has specific meanings for certain applications, such as representing beta particles, and beta radiation. In regression analysis, "B" symbolizes non-standardized partial slope coefficients, whereas "β" represents standardized (standard deviation-score form) coefficients; in both cases, the coefficients reflect the change in the criterion Y per one-unit change in the value of the associated predictor X.

In the International Phonetic Alphabet, Greek minuscule beta denotes a voiced bilabial fricative.

Common difficulties

In typesetting technical literature, it is a commonly made mistake to use the German letter ß as a replacement for the β. The two letters resemble each other superficially, but they are unrelated.

The Unicode number for β is U+03B2, and with β or β the β is coded in HTML. The internal version, ϐ, is encoded as U+03D0 in Unicode or ϐ in HTML.
