What ጿ means
It represents one syllable inside an Ethiopic word.
Where did Ethiopic writing come from?
It grew from South Arabian writing in the Horn.
South Arabian settlers and stonemasons from Sana'a and Marib brought Sabaean language and writing into Tigray around the 8th century BCE. Inscriptions show distinct Ethiopic writing by the 2nd–3rd centuries CE.
Royal inscriptions from Aksum, an ancient kingdom, show Geʿez in South Arabian and early Ethiopic writing. By the 4th century, vowel marks made each sign represent a consonant-and-vowel syllable.
