This language is the most widely spoken that features classificatory verb stems based on whether the object is one of several types, including (15[1])“Flat Flexible Object” and (15[1])“Mushy (15[1])Matter.” The only word in this language that has been fully absorbed into English is this language’s term for home, hooghan. (15[1]-5[2])Edward (15[1])Sapir (-5[1])coined the name of a family (-5[1])whose most spoken language is this one by adding (15[1])the (-5[1])prefix (*) “Na” (10[1])to (10[1])its endonym.

For 10 points, speakers of what Native American language were employed as “code (10[1])talkers” (10[4])in (10[1])World War II? (10[1])■END■ (10[2])
