Umbrian is an extinct Italic language formerly spoken by the Umbri in the ancient Italian region of Umbria. Within the Italic languages it is closely related to the Oscan group and is therefore associated with it in the group of Osco-Umbrian languages. Since that classification was first formulated a number of other languages in ancient Italy were discovered to be more closely related to Umbrian. Therefore, a group, the Umbrian languages, was devised to contain them.

Approximate distribution of languages in Iron Age Italy during the 6th century BC
Umbrian is known from about 30 inscriptions dated from the 7th through 1st centuries BC. The largest cache by far is the Iguvine Tablets, seven  inscribed bronze tablets found in 1444 near the village of Scheggia or, according to another tradition, in an underground chamber at Gubbio (ancient Iguvium). The seven tablets contain notes on the ceremonies and statutes for priests of the ancient religion in the region. Sometimes they are called the Eugubian tablets after the medieval name of Iguvium/Eugubium. The tablets contain 4000-5000 words.
The Iguvine tablets were written in two alphabets. The older, the Umbrian alphabet, like other Old Italic script, was derived from the Etruscan alphabet, and was written right-to-left. The newer was written in the Latin script. The texts are sometimes called Old Umbrian and New Umbrian. The differences are mainly orthographic. For example, <rs>in the Latin alphabet is represented by a single character in the native script (generally transcribed as ř; this represents an unknown sound that developed regularly from intervocalic *-d- in most cases). 
History of SoundsEdit
Compared to its highly conservative sister language Oscan, Umbrian exhibits a number of innovations, some of them shared by its neighbor to the west, Latin.
All diphthongs are simplified (a process only partly seen in Latin, and only very rarely in Oscan).
Velars are palatalized and spirantized before front vowels and the front glide /j/ (as happened later in most Romance languages).
Like Latin, but unlike Oscan, intervocalic -s- rhotacized to -r-. In late forms of the language, final -s also becomes -r (a change not seen in Latin). 
Taken from the Iguvine Tablets, tablet Va, lines 6-10 (written in the native alphabet on the tablet):
(6) ...Sakreu (7) perakneu upetu, revestu, puře teřte, (8) eru emantu herte, et pihaklu pune (9) tribřiçu fuiest, akrutu revestu (10) emantu herte...
In Latin: (6-7) ...Hostia solemnis digito, revisito, cum datur, (8) (aliquae) earum accipiantur oportetne, et cum piaculorum (9) ternio fiet, ex agro revisito (10) accipiantur oportetne... 
In English: (6-7) Let him select the sacrificial victims, and when they are given over, let him inspect them (8) to see if (any) of them are to be accepted, and in the case of (9) a triple offering, let him inspect them in the country (10) to see if they are to be accepted. 
Taken from the Iguvine Tablets, tablet VIa, lines 25-31 (written in the Latin alphabet on the tablet):

"(25)...Iovi Grabovie huius opere, si in montis Fisie ignis ortus est (26) civitate Iguvina, ritus debiti omissi sunt quasi nec consulto.

"(25)...Jupiter Grabovius, if on the Fisian mount fire has arisen, or if in the (26) nation of Iguvium the owed preparations have been omitted, let it be as if they had been made.

Jupiter Grabovius, purify the name of the Fisian Mount (and) of the Iguvine state, purify the magistrates (and) formulations, men (and) cattle, heads (of grain) (and) fruits, Be favorable (and) propitious in your peace to the Fisian Mount, (31) to the Iguvine state, to the name of that, to the name of this. Jupiter Grabovius, keep safe the Fisian Mount, keep safe the Iguvine state."
