The northeastern Iberian script, also known as Levantine Iberian or Iberian because the Iberian script was the most frequently used, was the main means of written expression of the Iberian language. The language is also expressed by the southeastern Iberian script and the Greco-Iberian alphabet. To understand the relationship between northeastern Iberian and southeastern Iberian scripts, one should point out that they are two different scripts with different values for the same signs. However, it is clear they have a common origin and the most accepted hypothesis is that northeastern Iberian script was derived from the southeastern Iberian script. Some researchers have concluded that it is linked to the Phoenician alphabet alone, but others believe the Greek alphabet also had a role.
