What does the name Sydney stand for?

Answer 1

It does not have a meaning in general, though some scholars suggest that it was a name of someone who, in the past, did something remarkable, and a city was named after them. Some other scholars argue that most cities have no point to there name, including Sydney. But, like the city Puyallup, was named after the Puyallup Native Americans, and the name Yellowstone was named for the great rocks, or stones found in thee park, that are a strange shade of yellow.
