Walaal, the Prophet PBUH blesse Ardul Habash. At that time that region was much different then the Ethiopia region we know and it was certainly not confined to the Amhara region alone. Rather it is presumed the Ardul Habash stretched from all the way what is known today as Eritrea to Adal(Harar, Zaylac) could have included other part of the Horn, Allah Aclam.
Laakiin how did you come to conclusion that just by observing the Alphabet the Amhara are more ancient? BTW we also have old unique written script.
Somali (af Soomaali)
Somali is a member of the East Cushtic branch of the Afro-Asiatic language family. It has 10-16 million native speakers and perhaps half a million second language speakers mainly in Somali, where it is an official language, Ethiopia, Djibouti and Kenya. There are also significant numbers of Somali speakers in Europe, North America and Yemen.
Somali has been written with four different scripts: an Arabic-based abjad known as Wadaad's writing, a Latin-based alphabet and two native alphabets, the Osmanya script and the Borama script.
Wadaad's writing (Arabic script)
The Arabic script was first introduced in the 13th century by Sheikh Yusuf al-Kowneyn to aid Koranic teaching. In the 19th century Sheikh Uways al-Barawi improved the writing of Somali with the Arabic script and based it on the Maay dialect of Southern Somalia. A Somali linguists, Muuse Xaaji Ismaaciil Galaal, radically altered the spelling conventions for Somali written with the Arabic script and introduced a set of new symbols for the vowels in the 1950s.
Borama/Gadabuursi alphabet
In 1933 Sheikh Abdurahman Sheikh Nuur invented another script for Somali known as Borama or Gadabuursi which was only used by the Sheikh's small circle of associates in Borama.
Somali/Osmanya alphabet
The Osmanya alphabet was created in between 1920 and 1922 by Cismaan Yuusuf Keenadiid, brother of the Sultan of Obbia. In Somali it is known as far soomaali (Somali writing) or cismaanya. It replaced an attempt by Sheikh Uweys to devise an Arabic-based alphabet for Somali, and has in turn been replaced by the Latin orthography of Muuse Xaaji Ismaaciil Galaal (1914-1980).
The Osmanya alphabet is not used much these days, though during the 1970s quite a number of people used it for personal correspondence and bookkeeping. A few books and magazines have also been published in the alphabet.
Notable features
Direction of writing: left to right in horizontal rows.
The names of the letters are based on Arabic letter names.
The letters waw and ya are used to write the long vowels uu and ii respectively.
Somali is a tonal language with four tones which are not usually marked in writing. The tones have grammatical uses: theny indicate number, gender and case.
Latin alphabet for Somali
In 1961 both the Latin and Osmanya scripts were adopted for use in Somalia, but in 1969 there was a coup, with one of its stated aims the resolution of the debate over the country's writing system. The Latin alphabet was finally adopted in 1972 and at the same time Somali was made the sole official language of Somalia. Shire Jama Ahmed (Shire Jaamac Axmed / شيري جامع أحمد) is credited with the invention of this spelling system, and his system was chosen from among eighteen competing new orthographies.
