Osco-Umbrian languages

The Osco-Umbrian, Sabellic or Sabellian languages are an extinct group of Italic languages, the Indo-European languages that were spoken in central and southern Italy by the Osco-Umbrians before being replaced by Latin, as the power of ancient Rome expanded. Their written attestations developed from the middle of the 1st millennium BC to the early centuries of the 1st millennium AD. There is one text of about 4,000 words in Umbrian, but otherwise the languages are known almost exclusively from inscriptions, principally of Oscan and Umbrian, but there are also some Osco-Umbrian loanwords in Latin. Besides the two major branches of Oscan and Umbrian (and their dialects), South Picene may represent a third branch of Sabellic. The whole linguistic Sabellic area, however, might be considered a dialect continuum. Paucity of evidence from most of the "minor dialects" contributes to the difficulty of making these determinations.
