The Latino-Faliscan or Latinian languages form a group of the Italic languages within the Indo-European family. They were spoken by the Latino-Faliscan people of Italy who lived there from the early 1st millennium BC.
Latin and Faliscan belong to the group, as well as Lanuvian and Praenestine, which are sometimes considered dialects of Latin.
The concept of Italic peoples is widely used in linguistics and historiography of ancient Italy. In a strict sense, commonly used in linguistics, it refers to the Osco-Umbrians and Latino-Faliscans, speakers of the Italic languages, a subgroup of the Indo-European language family. In a broader sense, commonly used in historiography, all the ancient peoples of Italy are referred to as Italic peoples, including the non-Indo-European ones, as Rhaetians, Ligures and Etruscans. As the Latins achieved a dominant position among these tribes, by virtue of the expansion of the Roman civilization, the other Italic tribes adopted Latin language and culture as part of the process of Romanization.
Old Latin, also known as Early, Archaic or Priscan Latin (Classical Latin: prīsca Latīnitās, lit. 'ancient Latinity'), was the Latin language in the period roughly before 75 BC, i.e. before the age of Classical Latin. A member of the Italic languages, it descends from a common Proto-Italic language; Latino-Faliscan is likely a separate branch from Osco-Umbrian. All these languages may be relatively closely related to Venetic and possibly further to Celtic (see the Italo-Celtic hypothesis).
The use of "old", "early" and "archaic" has been standard in publications of Old Latin writings since at least the 18th century. The definition is not arbitrary, but the terms refer to spelling conventions and word forms not generally found in works written under the Roman Empire. This article presents some of the major differences.
The Umbri were an ancient people, considered an Italic people, attested during the Iron Age in inner central Italy, approximately between the middle Tiber river and the central Apennines. A region called Umbria still exists and is now occupied by Italian speakers. It is somewhat smaller than the ancient Umbria. Most ancient Umbrian cities were settled in the 9th-4th centuries BC on easily defensible hilltops. Umbria was bordered by the Tiber and Nar rivers and included the Apennine slopes on the Adriatic. The ancient Umbrian language belongs to the Osco-Umbrian branch of the Italic languages, an Indo-European subfamily that also includes the Latino-Faliscan languages.
The Faliscan language is the extinct Italic language of the ancient Falisci, who lived in southern Etruria at Tiber Valley. Together with Latin, it formed the Latino-Faliscan languages group of the Italic languages. It seems probable that the language persisted, being gradually permeated with Latin, until at least 150 BC.
