father, further (see usage note)
Although some usage guides insist that only farther should be used for physical distance (We walked farther than we planned), farther and further have been used interchangeably throughout much of their histories. However, only further is used in the adverbial sense “moreover” (Further, you hurt my feelings) and in the adjectival senses “more extended” (no further comment) and “additional” (Further bulletins came in).
The expression all the farther (or further) in place of as far as occurs chiefly in informal speech: This is all the farther the train goes.
Origin: 1300-50; Middle English ferther; orig. variant of further
