What does farthest mean?
Farthest is the superlative form of far, used to describe the most distant point, place, or extent within a comparison. It appears chiefly as an adjective ('the farthest planet from the sun') and as an adverb ('she traveled farthest of anyone in the group'). Beyond physical distance, it extends naturally into figurative territory: writers speak of the farthest reaches of the ocean, the farthest corners of memory, or pushing ideas to their farthest limits. In American English, farthest is the standard superlative for literal distance, while its close twin furthest is favored in British English, particularly for abstract or metaphorical extension — a regional split that makes the word a small marker of linguistic habit. The word carries connotations of remoteness, extremity, and achievement at the edge of possibility, making it useful wherever distance, whether measured in miles or ambition, is at stake.
At, near, or relating to the greatest distance; most distant in space or time.
"The farthest house on the lane belongs to a retired lighthouse keeper."
To or by the greatest distance or extent; more than anything else in terms of distance reached.
"Of all the competitors, he threw the javelin farthest."
'Farthest' and 'furthest' mean exactly the same thing — but Americans overwhelmingly pick one and Brits often pick the other.

Etymology of farthest
Farthest is formed from 'far', an Old English adverb (feorr) meaning distant or remote, with the double comparative-superlative ending -er/-est added on top of the older -th- form. This gives it the same layered structure seen in other English superlatives like 'most' (from Old English mǣst). Its sibling 'furthest' derives from 'further', which has a related Germanic origin, and both have long coexisted in English. Cognates appear across the Germanic family, including German 'fern' and Dutch 'ver', all tracing back to the same ancient root meaning 'to go, travel'.
