The only known full Paleohispanic signary, on the undated Espanca tablet (not completely readable, but clearly related to the southwestern and southeastern scripts), follows the Phoenician/Greek order for the first 13 of its 27 letters: Α Β Γ Δ Ι Κ Λ Μ Ν Ξ Π? Τ. The fact that southern paleohispanic /e/ appears to derive from the Phoenician letter ‘ayin, which gave rise to Greek Ο, while southern iberian /o/ derives from another letter or was perhaps invented,Ramos, A Palæo-Hispanic Alphabet: Espanca's Stele suggests that the development of vowels in Paleohispanic semi-syllabaries was independent of the Greek innovation. However, the order of what appears to be /u/ directly after Τ, rather than at the place of , has suggested to some researchers a Greek influence. (In addition, the letter for /e/ in northeast Iberian resembles Greek Ε rather than the southeast Iberian letter.) The two sibilants, S and S', are attested, but there is one sign too few to account for a full 15-sign syllabary and all four of the letters M, M', R, and R' (not all of which can be positively identified with letters from the tablet), suggesting that one of ems or ars shown in the charts to the right is only a graphic variant.
