Although they are often used interchangeably, "further" and "farther" don't have exactly the same meaning. Basically, "farther" refers to actual distances between objects while further refers to figurative distances or something that is additional or more. Here are some easy-to-understand definitions and examples of how to use the two words.
Further vs. Farther
"Farther" for Measurable Distance
Farther refers to a greater physical distance, a distance that has been measured.
Examples of Farther
When used as an adjective, "farther" describes when one object is more distant than the other, requiring a measurement of the distance from one common point to both objects.
- The red car is farther away than the blue car.

Quick Usage Trick
One of our YourDictionary readers shared a great way to help you use "further" and "farther" correctly:
"If you can't replace "further" with "additional" or "more" in a sentence, you are probably using it incorrectly."
