Amharic is the official working language of the Federal Democratic Republic of Ethiopia which is spoken by almost 30% of the population. It is written left-to-right using Amharic Fidel which grew out of the Ge'ez abugida—called, in Ethiopian Semitic languages, abugida. There has not been much published about Amharic dialect differences. All dialects are mutually intelligible, but certain minor variations are noted.
