Final answer:
To use Amharic in Power Ge'ez, one needs software that supports the Ge'ez script. Amharic, which utilizes this script, is a primary language in Ethiopia and is often used in elementary education, though English is the language for higher education. The use of Amharic is however adapting with changing linguistic demographics and the increasing prominence of other local languages.
Step-by-step explanation:
To use Amharic in Power Ge'ez, which is a reference to the Ge'ez script -- the ancient writing system that Amharic is derived from -- you would need software that supports the Ge'ez script, as Amharic is written with this script. In Ethiopia, while English is the language of higher education, Amharic is widely used in elementary schools and is a lingua franca. However, the usage of Amharic is starting to adapt due to increasing population and the rise in usage of other local languages within the country. Eritrea, which also has historical ties with Ge'ez, predominantly uses the Tigre and Tigrinya languages that use the Ge'ez script as well.
