"I am eating hamburger and potatoes."
Translation:Béégashii bitsįʼ dóó nímasii yishą́.
Apparently so. Note that bitsįʼ basically means meat (see Wiktionary entry for bisóodi bitsįʼ, which means "pork"). Wiktionary further notes that bitsįʼ really means "its meat" (or, in all the cases we've seen in this lesson, I guess, "the meat of the animal name preceding it"), and it's based on the basic noun form of meat, atsįʼ.
