Knowing when to use farther versus further is one of the most common challenges in English grammar. While they share the same roots and sound nearly identical, they serve different functions in modern American English. One measures physical space, while the other measures figurative progress or degree.
Quick Answer: The Main Difference
The distinction lies in measurability. If you can measure the distance with a ruler, odometer, or tape measure, use Farther. If the distance is abstract, metaphorical, or refers to time/degree, use Further.
Use “Further” (e.g., “We need to discuss this further.”)

Farther: Defined by Physical Distance
The word farther relates directly to the word far. It is exclusively used to describe a measurable physical distance. If you are talking about miles, kilometers, feet, or meters, this is the correct choice.
Think of farther when you deal with geography or spatial separation. It implies that point A is a specific length away from point B.
Examples of “Farther” in a Sentence
- “The gas station is farther down the road than I thought.” Correct
- “I can throw the ball farther than you.” Correct
- “Pluto is farther from the sun than Neptune.” Correct
- “We need to discuss this farther.” Wrong (You cannot measure a discussion in meters.)
Further: Figurative and Abstract Degree
The word further suggests advancement, degree, or time. It is used for situations where physical measurement is impossible. When you mean “more,” “additional,” or “to a greater extent,” you should use further.
This version often acts as a synonym for “additional”. If you can replace the word with “additional” or “more” in your sentence, further is usually the right pick.
Examples of “Further” in a Sentence
- “Do you have any further questions?” Correct
- “Nothing could be further from the truth.” Correct
- “We will investigate this matter further.” Correct
- “My house is further down the street.” Often Accepted (But technically farther is more precise here in US English.)Source-1✅
Comparison: Farther vs. Further
Here is a direct breakdown to help you visualize which word applies to your specific context.
| Feature | Farther | Further |
|---|---|---|
| Primary Use | Physical distance | Metaphorical distance, time, degree |
| Root Word | Far | Fore (meaning front or earlier) |
| Measurability | Yes (Miles, Km, Steps) | No (Abstract concepts) |
| Can be a Verb? | No | Yes (e.g., “To further a career”) |
| Can be an Adjective? | Yes | Yes |
The Exception: “Further” as a Verb
One distinct advantage further has over its counterpart is that it can function as a verb. You can “further” a goal, a career, or a project. You cannot “farther” anything.
Usage Rule: If the word describes the action of helping something progress or succeed, it is always further.
- “She took extra classes to further her education.” Correct
- “He wants to farther his career.” Incorrect
Regional Differences: UK vs. US English
Language evolves differently depending on where you are. The strict separation between these two words is largely a prescriptive rule in American English.
In British English, the lines are much blurrier. It is quite common for British speakers to use further for both physical distances and abstract degrees. However, even in the UK, using “farther” for abstract concepts (like “farther education”) is considered incorrect.
If you are writing for an American audience or adhering to strict academic standards (APA, MLA), you must maintain the distinction: Farther for space, Further for degree.Source-2✅
How to Remember: The “Far” Trick
If you struggle to recall which spelling to use, look at the spelling of the word itself. Farther contains the word “FAR”.
Quick Memory Aid:
If you can replace the word with “a long way”, it likely contains the word “Far” (Farther). If you cannot, use Further.
Frequently Asked Questions
Common Questions About Farther and Further
Can I use “further” for physical distance?
In casual conversation and British English, yes, “further” is often used for physical distance (e.g., “I walked further”). However, in formal American writing, it is safer to stick to “farther” for physical measurement to avoid correction.
Is “farther” ever used as a verb?
No. “Farther” works as an adverb or an adjective, but never as a verb. You cannot “farther” a plan; you can only “further” it.
What are the superlative forms?
The superlative of farther is farthest (most distant physically). The superlative of further is furthest (most distant conceptually or abstractly).
Does “further” mean “more”?
Yes. “Further” is frequently used as a synonym for “additional” or “more,” such as in the phrase “for further information.”
