I want to know the answer to the following question:
What did the Sumerians refer to themselves as in their language?
All the background I'm provided with is that "𒌦 𒊕 𒈪 𒂵), phonetically /uŋ saŋ giga/, literally meaning "the black-headed people", and to their land as ki-en-gi(-r) ('place' + 'lords' + 'noble'), meaning "place of the noble lords".". Is that enough to answer the question?
Answer: yes
