Appendix:Afroasiatic Swadesh lists - Wiktionary, the free dictionaryIn Semitic languages [4], a hypothetical transition from biconsonsonantal (2c) to triconsonantal (3c) language morphology was debated for quite some time [5]. Semitic lexemes are derived from roots consisting of predominantly three radicals (i.e., root consonants), termed 3c. However, there is a small corpus of 2c roots (defined in Methods), responsible for most of the irregular Semitic verbs. Are these remnants from a more archaic linguistic phase? One observation favoring this is the relative abundance of 2c body parts and, particularly facial features (“eye”, “tooth”, etc.). If this semantic field originated early in language development then so did the 2c morphology. But how can we know this?
Further progress can be made by correlating linguistic and archeological innovations. Selecting an archeologically dateable semantic field (e.g., materials), we have shown [6] that, in the reconstructed Proto-Semitic (PS) language [7,8], names of materials known to and utilized by early hunter-gatherers (wood, reed, stone, flint, lime, gravel, sand, mud, clay, cloth, skin and water) are overwhelmingly (85%) of 2c morphology, while materials introduced as of the Neolithic period in W. Asia (bitumen, sulfur, salt, charcoal, pottery, brick, wool, lead, antimony, copper, silver and gold) were all given 3c names. This non-uniform distribution of 2c vs. 3c lexemes in these two semantic fields suggests that a 2c > 3c language morphology change accompanied the transition to agriculture in the Early Neolithic, ca. 11,000 years Before Present (BP).
For instance, "head" is Arabic ra`s, Hebrew rôsh, Syriac rêsha, Akkadian rêshu, Ge'ez rəʾəs
Likewise, "name" is Arabic ism, Hebrew shem, Syriac shma, Akkadian shumu, Ge'ez səm
That's the time of the dispersion of the Proto-Semitic speakers, when different subsets of them went in different directions.One can nowadays reconstruct PS rather reliably [8] thanks to the extensive Akkadian (Akk.) texts [9], which go back 2.5–4.5 kyr. PS was supposedly spoken during the Chalcolithic period, sometime between 5,750 BP [10] and 6,300 BP [11].
This age is roughly the age of Indo-European and other relatively old generally-accepted language families.
