I find it interesting that the Amharic word for metal is ብረት/Bireti given that the Somali word for metal is Bir, like the name of Ethiopia's currency. This is interesting stuff because the Horn in general has very linked traditions for how craftsmen blacksmiths were historically treated and operate which sort makes me think metallurgy among Somalis likely originated in the Ethiopian Highlands and spread to us along with the word sometime within the last 2,000-3,000 years.
