After sound changes eliminated /w/ from spoken Greek, digamma was used only as a numeral. Source: Internet
However, the Greek alphabet also gave rise to other alphabets, and some of these retained letters descended from digamma. Source: Internet
These metrical inconsistencies (along with a knowledge of comparative linguistics) have led scholars to infer the presence of a lost digamma consonant in an old form of that line. Source: Internet
Latin 'F,' despite being pronounced differently, is ultimately descended from digamma and closely resembles it in form. Source: Internet
The digamma function, which is the derivative of this function, is also commonly seen. Source: Internet
