The place to begin is with a definition of what can be called a Punic script in relation to a Punic language. Conventionally, we call "Punic" the writing typical of Carthage, which spread to other colonies when the "New City" became the "capital" of the Phoenician west. Judging from the existing data on the history of the region, Carthage became leader of the other colonies around the middle to the end of the 6th century BC, when we first know of symbola with the Etruscan cities, the first treaty with Rome (ca. 509 BC), and the first Carthaginian involvement in wars in Sardinia and Sicily. One can suppose that, before this period, the Phoenician language, written according to Phoenician orthographic and paleographic conventions, was still in use in the west, with some local changes in the scripts from region to region or from city to city… As for language, the Phoenician-Punic grammars (the authors of which generally do not agree on the classification of the different phases and dialects of Phoenician) make a distinction between Phoenician and Punic. They lack precision, however, when they attempt to define the characteristics of Punic and the period in which it originated… We are able to distinguish Punic from Phoenician (in part) because of the orthography of the written language. The first linguistic characteristic we can recognize is the tendency to drop the pronunciation of the laryngeal ʾalep, followed by he (in Punic), and finally, the whole series of laryngeals and pharyngeals (in late Punic).

The hybrid nature of these earliest signs gives us clues regarding the sociohistorical context for the origins of the alphabet. On the one hand, most if not all of these earliest pictographs have plausible connections to Egyptian hieroglyphic (and perhaps hieratic) symbols, implying that the inventors were influenced at some level by Egyptian writing. On the other hand, the phonemes represented by these symbols are derived from the West Semitic (and not Egyptian) words behind the pictographs. For instance, the sign for a hand is used to denote the /k/ sound through the West Semitic word kaph for "palm" or "hand", a word that also comes to be the name of the letter. (For comparison, the Modern Hebrew name for the corresponding letter is precisely kaph; note also the Greek letter name kappa.) This association of the letter name (kaph) with its initial phoneme (/k/) is called the acrophonic principle (acro- "topmost" + phone "voice, sound"), and the fact that it is via the Semitic vocabulary that such a principle operates suggests that the linear alphabet arose for the purpose of writing a Semitic language. In fact, it is based on this assumption that the Sinai inscriptions have been partially deciphered, 6 revealing intelligible phrases such as lbat ("for the Lady") and rb nqbnm ("chief of the miners").
