I don't understand "Sa sa ye la?" How could it mean "what is this?" Please, please explain.

Sa     |  sa   |   ye |  la    |  (contracted)

Kisa  |  sa   |   ye |  la    |  (uncontracted)

What |  that |   is   |  here |  (translation in English)

Thus,
Sa sa ye la? → What is that / this?

Sa sa yo ye la? → what are these/those?

Explain: "Ki sa sa ye"

Kisa → what
Ye → to be
sa → this, that, it

Kisa sa ye?
What is that?

Kisa sa yo ye?
What are those?

Kisa yo ye?
What are they?

Kisa li ye?
