The story of Semitic
01
From Medieval Grammarians to the Name 'Semitic'
The kinship of Hebrew, Aramaic and Arabic was noticed long before modern linguistics. Jewish scholars living under Islamic rule, who often knew all three, compared them systematically. Around 900 CE Judah ibn Quraysh of Tahert, in North Africa, wrote a letter (the Risāla) urging the Jews of Fez to keep up their Aramaic because it and Arabic explained many difficult words in the Hebrew Bible. Grammarians such as Saadia Gaon and Jonah ibn Janah drew on Arabic grammar to describe Hebrew.
In Europe, Christian Hebraists of the 16th and 17th centuries learned Syriac, Arabic and Ethiopic side by side; Hiob Ludolf's grammar of Ge'ez (1661) placed Ethiopic firmly in the group. The name came later. In 1781 the historian August Ludwig von Schlözer called these languages 'Semitic', after Shem, the son of Noah from whom Genesis 10 derives several of the peoples who spoke them. The label is biblical and ethnically loose, since the Canaanites who wrote Phoenician are sons of Ham in that chapter, but it stuck.
What made the case was not a scattering of look-alike words but whole systems in common: the consonantal roots, the personal pronouns, the numerals, and verbs conjugated with the same prefixes and suffixes. The 19th century widened the group dramatically. When Akkadian cuneiform was deciphered in the 1850s, by Edward Hincks, Henry Rawlinson, Jules Oppert and others, it proved to be Semitic and far older than anything known before. Ugaritic followed in 1930, deciphered within months of its discovery, and Eblaite in the 1970s. Carl Brockelmann's two-volume comparative grammar (1908–13) set out the family's shared structure in a form that remained the standard reference for most of the 20th century.

A Homeland in Dispute
The earliest firm evidence for Semitic is in Mesopotamia and Syria: Semitic personal names in Sumerian documents from about 2600 BCE, then Akkadian and the archives of Ebla in the 24th century BCE. By then the family had already split into East and West Semitic, so Proto-Semitic must be older, probably fourth millennium BCE or earlier.
Where it was spoken is disputed. A long-standing 19th- and early 20th-century view placed the homeland in the Arabian Peninsula and pictured Semitic history as a series of 'waves' of nomads out of the desert. That picture has largely been abandoned: it rested on assumptions about nomads rather than on linguistic evidence. Most specialists now favour the Levant or northern Mesopotamia. The reconstructed vocabulary points to settled farmers and herders, with words for sheep, goats and cattle and for cultivated crops, rather than to desert pastoralists. The Bayesian study of Kitchen and colleagues (2009), built on basic vocabulary, supported a Levantine origin around 3750 BCE; its method and dates have been criticised, but its geography agrees with the majority view.
A minority argue for Africa. Semitic is the only branch of Afroasiatic spoken outside Africa, and a family is most often born where its branches are most diverse, which for Afroasiatic means north-east Africa. On this view the ancestors of the Semites crossed into Asia, perhaps through Sinai, before Proto-Semitic split. The two views are not wholly opposed: an African origin for Afroasiatic is compatible with an Asian homeland for Semitic itself.
Later expansions are much better documented. Aramaic spread as an imperial lingua franca from the 8th century BCE, Semitic speakers from Arabia crossed the Red Sea into the Horn of Africa in the first millennium BCE, and Arabic spread with Islam from the 7th century CE across the Middle East and North Africa.

What Is Still Argued Over
The largest unresolved question is where the southern languages belong. The Modern South Arabian languages of Yemen and Oman (Mehri, Soqotri and others) and the extinct Old South Arabian of the ancient kingdoms of Saba and Himyar are drawn directly from West Semitic, without a South Semitic node. Hetzron and many after him grouped them with Ethiosemitic as 'South Semitic', on the strength of shared verb forms. Others, including Huehnergard and Rubin, find the shared innovations too few and prefer to leave them as separate branches of West Semitic. The debate shades into a larger one about method: whether Semitic is best described as a tree at all, or as a chain of dialects in which innovations spread in overlapping waves.
Smaller placements are also contested. Eblaite is usually grouped with Akkadian, but some scholars see it as a separate branch or as closer to West Semitic. Whether Ugaritic is a kind of Canaanite or its own branch of Northwest Semitic is unsettled, and so is whether Arabic belongs with Northwest Semitic, as this tree has it, or apart.
The sounds of Proto-Semitic are argued over too. Its three sibilants are traditionally written *s, *š and *ś; a growing number of scholars, following Richard Steiner and Alice Faber, hold that what is written *s was really an affricate [ts] and *š a plain [s]. Whether the emphatics were ejective, as in Ethiopia today, or pharyngealised, as in Arabic, is still disputed.
Dates rest largely on inference, since the family was already divided when writing began, and computational estimates such as Kitchen's have not settled the matter. Above Semitic, the relationships among the branches of Afroasiatic, and where that family began, remain open questions.
