The Greek alphabet
has been used to write the Greek language
since the 8th century BC. It was derived from the earlier Phoenician alphabet
, and was the first alphabetic script to have distinct letters for vowels as well as consonants. It is the ancestor of the Latin
and Cyrillic scripts
. Apart from its use in writing the Greek language, in both its ancient and its modern forms, the Greek alphabet today also serves as a source of technical symbols and labels
in many domains of mathematics, science and other fields.
