There is no agreement about how the paleohispanic semi-syllabaries originated; it is typically agreed that their origin is linked to the Phoenician abjad, but some believe the Greek alphabet had an influence. In the southwestern script, although the letter used to write a stop consonant was determined by the following vowel, as in a full semi-syllabary, the following vowel was also written, as in an alphabet. A similar convention is found in Etruscan for /k/, which was written "" depending on the following vowel. Some scholars treat Tartessian as a redundant semi-syllabary, others treat it as a redundant alphabet.
