 The tribesmen lived in different parts of the region, with those living among the mountains known as the "al-Jabaliyyun" (the Mountaineers), those on the plain (mostly from Al Jadila) known as "as-Sahiliyyun" (the Plainsmen) and those on the desert sands known as "al-Ramliyyun".The Tayy were so widespread and influential throughout the Syrian Desert that Syriac authors from Mesopotamia used their name, "Taienos", "Tayenoi", "Taiyaya" or "Tayyaye" (), to describe Arab tribesmen in general in much the same way "Saracenos" was often used by authors from Byzantine Syria and Egypt as a generic term for Arabs.The Syriac word was also entered into the language of the Sasanid Persians as "Tāzīg" () and later "Tāzī" (), also meaning "Arab".
