What does th latin word soros mean?

Soros does not mean anything in Latin. However Soros could potentially come from sorus, which in Greek means heap or pile.

It could also reference George Soros, who is a prominent American investor and philanthropist of Hungarian birth who is the chairman of Soros Fund Management, an international investment management company he founded in 1970 that's known for hedge fund management. Therefore this name potentially originates from Greek (Soros).
