Furtherとfartherの違いは何ですか？

What is the difference between further and farther?

"Further" and "farther" are often used interchangeably, but they do have a subtle difference in meaning.

"Further" typically refers to a greater extent or degree, as in "I need to further my education to get a better job."

"Farther" typically refers to a greater physical distance, as in "I need to drive farther to get to the next town."

So, in general, "further" is used to refer to abstract or metaphorical distances, while "farther" is used to refer to physical distances. However, this distinction is not always strictly observed, and the two words are sometimes used interchangeably.

It's worth noting that in British English, "further" is often used to refer to physical distance as well, so "farther" is less commonly used in that context.
