Page "Digamma" Paragraph 1

Digamma / wau was part of the original archaic Greek alphabet as initially adopted from Phoenician.

Like its model, Phoenician waw, it represented the voiced labial-velar approximant and stood in the 6th position in the alphabet, between epsilon and zeta.

It is the consonantal doublet of the vowel letter upsilon (), which was also derived from waw but was placed at the end of the Greek alphabet.

Digamma / wau is in turn the ancestor of the Latin letter F. As an alphabetic letter it is attested in archaic and dialectal ancient Greek inscriptions until the classical period.
