What does farther mean?
Farther is an adverb and adjective meaning at or to a greater distance or extent. Its most common and clearly defined role today is describing literal, measurable space — how much farther one town lies from another, or how much farther a runner managed to go. It can also mark figurative progress ('farther along in the project'), though English speakers increasingly prefer 'further' for such abstract uses. The word descends from Old English 'fyrðra', meaning to aid or promote, which itself came from the stem of 'forth'. For centuries 'farther' and 'further' were simply variant spellings of the same word, with no distinction in meaning; the tidy modern rule that 'farther' means physical distance while 'further' means metaphorical or additional extent is largely a North American development, and even there it remains a guideline rather than an absolute law.
To or at a greater distance; to a more advanced point or greater extent.
"They drove farther north in search of the northern lights."
Best reserved for literal distance in careful American usage.
More distant or remote; located at a greater distance.
"The farther shore was barely visible through the mist."
(Formal) to advance or promote something further.
"The committee sought to farther the cause of educational reform."
Farther and further were once interchangeable spellings of the same word — the modern 'distance vs. degree' split is largely an American invention.

Etymology of farther
Farther derives from Old English 'fyrðra', a derivative of the stem behind 'forth', originally meaning to help or promote. In Middle English it appeared as 'further'/'farther' variants without semantic distinction, both meaning 'to a greater extent'. The spelling 'farther', influenced by 'far', gradually became associated specifically with physical distance, a differentiation cemented mostly in American English from the eighteenth century onward. It shares its Germanic root with 'first', 'forth', and 'from'.
How farther is actually used
In contemporary American usage, 'farther' is generally reserved for literal, measurable distance while 'further' handles abstract extension, degree, and additional points in argument. In British English the distinction is weaker, and 'further' commonly serves both roles. Some style guides treat them as interchangeable historically, but the farther = distance convention is now widely taught.
Easily confused with farther
Farther refers strictly to physical or measurable distance, while further is preferred for abstract extent, degree, or additional quantity — though in British English 'further' often covers both.
