Hey, my old account! How've ya been, old bean?
By the way, lexico, if I were you, I'd start out pronouncing し "shi", not "si", it'll make things a bit less confusing.
And yes, "oujisama" (long o) means prince, while "ojisama" (shortish o sound) means uncle, that's why I was poking fun at a site that spelled it "hoshi no ojisama".
