==Obsolete letters==

The original Greek alphabet included the letters digamma<ref>Earlier known as "wau" (ϝαυ)</ref> (Ϝϝ), san (Ϻϻ), and qoppa (Ϙϙ).<ref>http://www.tlg.uci.edu/~opoudjis/unicode/nonattic.html</ref> Digamma was dropped due to the loss of the sound it represented in Greek ([w]), and san and qoppa were dropped in favor of sigma and kappa. Digamma and Qoppa were preserved in certain Western dialects, and eventually evolved into the Latin letters F and Q.<ref>http://www.fonts.com/AboutFonts/Articles/Letterseries/LetterQ.htm</ref> Qoppa is still used occasionally as a Greek numeral, albeit in a different form (Ϟϟ).<ref>http://www.tlg.uci.edu/~opoudjis/unicode/numerals.html</ref>
