"further"

Hello,
It's true that "further" when pronounced with "far-ther" means physically further? And, when pronounced "further" means it could be mentally further?

please forgive my english at expressing things a bit complicated..

These are two different words, with different spellings. In the most correct usage, "farther" means at a greater physical distance. "Further" is less literal. The distinction is often ignored, and most English speakers probably don't even know about it.
