"The toponyms of the Macedonian homeland are the most significant. Nearly all of them are Greek."

“The language spoken by these early Macedonians has become a controversial issue in modern times. It seems not to have been so in antiquity. As we have seen, Hesiod made Magnes and Macedon first cousins of the Hellenes, and he therefore regarded them as speakers of a dialect of the Greek language. That he was correct in the case of the Magnetes has been proved by the discovery of early inscriptions in an Aeolic dialect in their area of eastern Thessaly. Then, late in the fifth century a Greek historian, Hellanicus, who visited the court of Macedonia, made the father of Macedon not Zeus but Aeolus, a thing which he could not have done unless he knew that the Macedonians were speaking an Aeolic dialect of Greek. A remarkable confirmation of their Greek speech comes from the Persians, who occupied Macedonia as part of their conquests in Europe c.510-480. Disagreements over this issue have developed for various reasons. In the second half of the fifth century Thucydides regarded the semi-nomadic, armed northerners of Epirus and western Macedonia as "barbarians", and he called them such in his history of events in 429 and 423. The word was understood by some scholars to mean "non-Greek-speakers" rather than "savages." They were shown to be mistaken in 1956, when inscriptions of 370-68, containing lists of Greek personal names and recording in the Greek language some acts of the Molossians, were found at Dodona in Epirus. This discovery proved beyond dispute that one of Thucydides "barbarian" tribes" of Epirus, the Molossians, was speaking Greek at the time of which he was writing. Demosthenes too called the Macedonians "barbarians" in the 340s. That this was merely a term of abuse has been proved recently by the discovery at Aegae of seventy-four Greek names and one Thracian name on funerary headstones inscribed in Greek letters.”

“All in all, the language of the Macedones was a distinct and particular form of Greek, resistant to outside influnces and conservative in pronunciation. It remained so until the fourth century when it was almost totally submerged by the flood tide of standardized Greek.”

“Hesiod first mentioned 'Makedon', the eponym of the people and the country, as a son of Zeus, a grandson of Deukalion, and so a first cousin of Aeolus, Dorus, and Xuthus; in other words he considered the 'Makedones' to be an outlying branch of the Greek-speaking tribes, with a distinctive dialect of their own, 'Macedonian'.”

“As subjects of the king the Upper Macedonians were henceforth on the same footing as the original Macedonians, in that they could qualify for service in the King's Forces and thereby obtain the elite citizenship. At one bound the territory, the population and wealth of the kingdom were doubled. Moreover since the great majority of the new subjects were speakers of the West Greek dialect, the enlarged army was Greek-speaking throughout.”

“The Balkan situation was far from secure, with the Odrysians and Scythians only recently defeated and with the Triballi still defiant. Yet Philip was confident of success in the interest of the Greek-speaking world and of Macedonia in particular.”

“There were two parts of the Greek-speaking world at this time which did not suffer from revolution and did not seek to impose rule over the city states. In Epirus there were three clusters of tribal states, called Molossia, Thesprotia and Chaoniathe other part of the Greek-speaking world extended from Pelagonia in the north to Macedonia in the south. It was occupied by several tribal states, which were constantly at war against Illyrians, Paeonians and Thracians.”
