U+03DC "Ϝ" Greek Letter Digamma Unicode Character

U+03DC "Ϝ" Greek Letter Digamma is a historical letter of the Greek alphabet, originally used to represent the sound /w/, a labial velar approximant that was present in early Greek but later lost from the standard phonology. Its name "digamma" derives from its shape resembling two gamma letters stacked or joined. This character was primarily employed in ancient Greek inscriptions and, over time, became obsolete in classical Greek, though it survived as a numeral representing the number six in the acrophonic and later Milesian numeral systems. In modern contexts, digamma appears in historical, linguistic, and mathematical typography, and its Unicode encoding ensures its preservation for scholarly and digital use.
