Approximate distribution of languages in Iron Age Italy during the 6th century BCE
Oscan is an extinct language of southern Italy. The language is also the namesake of the language group to which it belonged.
Oscan was spoken by a number of tribes, including the Samnites, the Aurunci, the Sidicini, and the Ausones. The latter three tribes were often grouped under the name "Osci". The Oscan group is part of the Osco-Umbrian or Sabellic family, and includes the Oscan language and three variants (Hernican, Marrucinian and Paelignian) known only from inscriptions left by the Hernici, Marrucini and Paeligni, minor tribes of eastern central Italy. The language was spoken from approximately 500 BCE to 100 CE.
General characteristics 
Oscan had much in common with Latin, though there are also many striking differences, and many common word-groups in Latin were absent or represented by entirely different forms. For example, Latin volo, velle, volui, and other such forms from the Proto-Indo-European root *wel ('to will') were represented by words derived from *gher ('to desire'): Oscan herest ('he shall want, he shall desire', English cognate 'yearn') as opposed to Latin vult (id.). Latin locus (place) was absent and represented by the hapax slaagid (place), which Italian linguist Alberto Manco has recently referred to a local surviving toponym.
In phonology, Oscan also showed differences from Latin: Oscan 'p' in place of Latin 'qu' (Osc. pis, Lat. quis) (similar to the P-Celtic/Q-Celtic change in the Celtic languages); 'b' in place of Latin 'v'; medial 'f' in contrast to Latin 'b' or 'd' (Osc. mefiai, Lat. mediae)..
Oscan is considered the most conservative of all the known Italic languages, and among attested Indo-European languages it is rivaled only by Greek in the retention of the inherited vowel system with the diphthongs intact.
Writing system 
The native Oscan alphabet and a transliteration are as follows.
The Z is pronounced [ts]. The letters Ú and Í are graphically derived from U and I, and do not appear in the oldest writings. The Ú represents an o-sound, and Í is a tense [ẹ]. Doubling of vowels was used to denote length; the exception is a long I which is written IÍ.
Sometimes Oscan was written in the Latin or Greek alphabet.
If it was written in the Latin alphabet, then the Z does not represent [ts] but instead [z], which is not written differently from [s] in the native alphabet.
If it was written in the Greek alphabet, it used an alphabet identical to the standard, with the addition of Heta for the sound [h] and another letter for the sound denoted in the native alphabet by V. The letters η and ω do not indicate quantity. Sometimes, the clusters ηι and ωϝ denote the diphthongs /ei/ and /ou/ respectively while ει and oυ are saved to denote monophthongs /iː/ and /uː/ in the native alphabet. Other times, ει and oυ are used to denote diphthongs, in which case o denotes the /uː/ sound.
History of sounds 
This history denotes the changes that took place from Italic to Oscan, starting with the Italic sound.
Vowels are regularly lengthened before ns and nct (in the latter of which the n is lost) and possibly before nf and nx as well. Anaptyxis, the development of a vowel between a liquid or nasal and another consonant, preceding or following, occurs frequently in Oscan. If the other consonant precedes, the new vowel is the same as that of the preceding vowel. If the other consonant follows, the new vowel is the same as that of the following vowel.
Short a remains in all positions. Long ā remains in an initial or medial position. Final ā starts to sound similar to [ɔː] so that it is written ú or, rarely, u.
Short e generally remains unchanged. Before a labial in a medial syllable, it becomes u or i. Before another vowel, e becomes í. Long ē becomes the sound of í or íí.
Short i becomes the sound of í. Long ī remains unchanged and is spelt with i.
Short o remains mostly unchanged, written ú. Before a final -m, o becomes pronounced like u. Long ō becomes the sound of u or uu.
Short u generally remains unchanged. After t, d, n, the sound becomes that of iu. Long ū generally remains unchanged. It may have changed to an ī sound for final syllables.
The sounds of diphthongs remain unchanged.
