Furthermost means the most distant — the one that sits farther away than all the others. You use it when several places or things are already far, and you want the last, outermost one: the furthermost cottage, the furthermost island, the furthermost corner of the field. It is an adjective, and it almost always comes before a noun. It is rather bookish. In ordinary talk, people say furthest or farthest; furthermost turns up more in stories and careful writing, where a writer wants a slightly old, map-and-journey feel. Though actually, even on the page furthest is the more natural word, and furthermost can sound a little stiff if you drop it into everyday speech.
