Though the shape of the signs of the Sudlusitanian inscriptions is very similar to those of the Meridional Iberian's ones, this system is not a semisyllabary, but an alphabet in which every sign is to be transcribed as only one phoneme/letter. There is only one difference with the Greek type alphabet: the occlusive sign is different depending on the following vowel. That is, there is a k sign when followed by an a vowel, other when followed by e and so on. It is as if in an Iberian semisyllabary we added always the respective vowel sign to the syllabic sign: ta-a, te-e, ti-i, and so on. The cases of absence of vowel after an occlusive sign are exceptional. Obviously such a system was unstable and there are a few inscriptions in which the same sign is used both before a and before e in a clear process of simplification.

    There are also a few inscriptions 'unorthodox' 'anomalous', with odd shape signs and maybe with structural differences, but these inscriptions don't form a group: every one has its own anomalies.

    As regards the sign transcription table below, there are some important points to notice. The transcription of the accented r (r') is conventional, based on the Meridional Iberian value, and it could be a third sibilant. Untermann doesn't accept the identification of ki (k before i), and there are not enough data to demonstrate whether bu actually isn't ku (and hence ku actually bu): I consider it more probable the option stated below, but Correa and Untermann prefer the opposite solution.

    One aspect of my reading system that has been unexpectedly overlooked is the interpretation that I suggest for the Sudlusitanian signs that resemble Phoenician 'heth': it wasn't quoted in the brief Untermann's tables, and hence neither by Guerra (who also repeats the tables' mistake that I consider Untermann's m as a variant of s'!!). My proposal is to interpret them according to the following vowel: before a or e I read it as t/d; whereas before o or u as p/b. That said, it should be enough, but I hope that with a drawing it'll be easier to understand.

    So (not exhaustively), respectively before a, and before e, TA and TE:

    Whereas before a back vowel o or u, BO and BU:
