Old Latin (also called Early Latin or Archaic Latin) refers to the Latin language in the period before the age of Classical Latin; that is, all Latin before 75 BC.
Diphthong changes from Old Latin (left) to Classical Latin (right)
Phonological characteristics of older Latin are the case endings -os and -om (later Latin -us and -um), as well as the existence of diphthongs such as oi and ei (later Latin ? or oe, and ?). Also the letter C is used to represent both Classical C and G.[1] In many locations, classical Latin turned intervocalic /s/ into /r/, which is called rhotacism. This rhotacism had implications for declension: early classical Latin, honos, honoris; Classical honor, honoris ("honor"). Some Old Latin texts preserve /s/ in this position, such as the Carmen Arvale's lases for lares.
Existing examples
The Forum inscription, one of the oldest known Latin inscriptions. It is written boustrophedon, albeit irregularly. From a rubbing by Domenico Comparetti.
Notable Old Latin fragments still in existence include:
The 'O-Stem Declension'. Nouns of this declension are either masculine or neuter.
campos, ?o? field, plain m.
saxom, ?o? rock, stone n.

Note the genitive plural ending has two endings: the earlier -?m, almost exactly like the Ancient Greek -?n, and the later Archaic Latin form -?som. Due to the fact that in Archaic Latin /r/'s and /s/'s were often interchangeable, a phenomenon known as rhotacism, the later -?som evolved into the Classical Latin -?rum.
Third declension (c)
The 'E-Stem ' and 'I-Stem ' Declension. This declension contains nouns that are masculine, feminine, and neuter.
Regs ?es king m.

The nominative as regs instead of rex shows a common feature in Old Latin; the letter x was seldom used alone to designate the /ks/ or /gs/ sound, but instead, written as either 'ks', 'cs', or even 'xs'.
Personal Prounouns
Personal pronouns are among the most common thing found in Old Latin inscriptions. Note how in all three persons, the ablative singular ending is identical to the accusative singular.
Ego, I
Tu, You
Su?, Himself, Herself, Etc.

The Relative Prounoun
In Old Latin, the relative pronoun is also another common concept, especially in inscriptions. Unfortunately, the forms are quite inconsistent and leave much to be reconstructed by scholars.

Old Present and Perfects
There is not much actual proof of the inflection of Old Latin verb forms and the few carvings we have hold many inconsistencies between forms. Therefore, the forms below are ones that are both proven by scholars through Old Latin carvings, and recreated by scholars based on other early Indo-European languages such as Greek, Oscan, Umbrian, and other Italic dialects.
