Ancient sources state that Siculians entered Sicily from the Italian Peninsula either around the 13th century or the middle of the 11th century BCE (or in two waves), driving the prior inhabitants, the Sicanians and Elymians, to the west of the island.2
Due to its limited attestation, it is difficult to determine much about this language beyond that it was Indo-European.3 The prevalent modern view is that Siculian was an Italic language, although the scarcity of sources and the difficulties in interpreting inscriptions and glosses make it impossible to come to a definitive conclusion.4
Some inscriptions may reveal Italic elements, such as geped ('had'), which is comparable to the Oscan hipid; dedaxed ('made' ?), perhaps a reduplicated k-extended form of the root *dʰeh1- similar to Volscian fhe:fhaked and Oscan fefacid; and the female name Kup(a)ra, which evokes the Sabellic *kupro- ('good').5
If Siculian is indeed classified as Italic, it would diverge from all its relatives in showing voiced reflexes of the Proto-Indo-European voiced aspirates in initial position, in contrast to the sound changes f < *dʰ, *bʰ and h- < *gʰ/*g̑ʰ, attested in Sabellic, in latin and Venetic.6
They used the Greek alphabet, along with a native one based upon Western Greek scripts, probably the Euboic-Chalkidic version.7 According to scholar Markus Hartmann, "of the fewer than thirty inscriptions in total, only six appear to be at least in part intelligible and to be Siculian (i.e., most certainly neither Greek nor belonging to some other Italic or pre-Italic language)."8

Some inscriptions, written in Sicilian Doric Greek and displaying lexical items that appear to match Latin, such as lítra (comparable to Latin lībra 'pound') and kúbiton (paralleling Latin cubitum 'elbow'), are also suspected to be of Siculian origin.15
