The Latin and other Italic peoples adopted the Greek alphabet
when the Greeks established colonies (settlements) in southern
Italy in the 8th century BC. The arrival of the Greeks had a
civilising impact on all the Italic peoples they came in contact
with. These peoples realised the usefulness of the Greek alphabet
for the development of their written languages. Some different
characters were created as adaptation to the phonetics (sounds) of
their languages which differed from that of the Greeks.
Archaic Latin, like all Old Italic alphabets in Italy (Etruscan,
Faliscan, Oscan, Umbrian, Picene, Messapic and Venetic) is thought
to have adopted the Cumae alphabet. Cumae was the northernmost
Greek settlement in Italy. This alphabet in its turn was a
variation of the Western Greek alphabet, one of the three archaic
Greek alphabets (the other two were the Cretese and the Ionic). The
Western one originated from the island of Euoboea, Boeotia and much
of the Peloponnese. These were areas many of the Greek settlers in
Italy came from.
It is thought that archaic Latin adopted 21 of the 29 Etruscan
letters. The Latin alphabet evolved into what has been called
classical Latin alphabet. This adopted two more Greek letters.
