Is there any difference between farther and further. I thought that I could say "Sydney is farther from London than Delhi." as well as "Sydney is further from London than Delhi." But I heard from one of the English teacher's that they are different. “Father” is a measure of distance! “Further” is a matter of degree! So an example would be “You can travel farther in one day by airplane then you can by a car.” “Further” is a matter of degree or aptitude. It’s a little more intangible, little bit more abstract than the very concrete “farther”. “Further” means something less tangible. So, an example might be “The learning of student group A isn't as further along student group B.” So this might mean the first Group, student group A progressed more rapidly in their learning in the language acquisition something like that So, if I say "Sydney is further from London than Delhi", would it be correct? Thank you!
