How to come up with city names?

[u/Diligent_Board_3999]

This is the city ive been working on building for the last year and a half i think (the walls are under renovations) and i need a better name for it i think. It was originally called redwood retreat, then solendor and now im wanting to change it again. I also want to name the continent so rhe world itself can have a better name than "forever world" but i havent come up with anything yet
