Farther vs. Further

Farther

We usually use farther to talk about a physical length or distance. Farther is the comparative form of far when talking about physical distance.

Important- If you can replace the word farther with a phrase like "more miles" or "more distance", then you are probably using it correctly.

Examples:

If you walk farther down the road, you will see the academy, Sure-shot Academy

(If you walk more miles down the road, you will see the academy, Sure-shot Academy)

The school is farther down Jograj Street.
(The school is more miles down Jograj Street.)

How much farther until we get there?
(How many more miles until we get there?)

Further

We usually use further to talk about a metaphorical distance, like a distance in time. It refers to a time or amount. Further is the comparative form of "far" when you mean "much." Further is another way of saying "additional" or "more time."

Examples:

His plan needs further study
(His plan needs additional study.)

I won't listen to this any further .
(I won't listen to this for any more time .)

Nishant sir wants to discuss this further
tomorrow.
(Nishant sir wants to discuss this for more time tomorrow.)
