This system is much less understood than Levantine or Greek-Iberian because of the scarcity of inscriptions and the great diversity of sign forms, with minor writing system variants ("diagrapses") in which the form that has a value in one can have another in other (owing to formal evolutions that make similar a sign to another, which in turn, as a chain reaction, changes its form in order to distinguish itself). The Meridional system is basically the same semisyllabic that the Levantine one but, as in Greek-Iberian, without the signs m and  m' (accented m). There are some signs (and variants) whose reading is unknown or argued. In the following table, besides the signs with a question mark, it's specially problematic the identification of ku, though it's the only probable reading. As the main decipherment method is the comparison with known Iberian words, hypothetical dialectal differences may be causing problems.

    As discovered by Correa, in some Meridional inscriptions exists a way to write a k or a t without a following vowel: this is the possible use of the signs ka and ti, which explains the occasional redundancy of the vowel in cases of ka-a and ti-i explicitly meaning that here the consonant does is followed by the vowel.
