What is "umbri"

]] The Umbri were an Italic tribe of ancient Italy. 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 is a branch of a group called Oscan-Umbrian, which is related to the Latino-Faliscan languages (Buck, 1904).
