What does outmost mean?
“Outmost” means the furthest from a centre, interior, or point of reference. It describes the position of something at the outside edge of a larger area or structure, such as the outmost branches of a tree, the outmost layer of an atmosphere, or the outmost walls of a building. The word has a distinctly literary or archaic tone and is now encountered far less often than the more familiar “outermost.” Its connotation is straightforward and spatial, though it can occasionally suggest extremity, remoteness, or a boundary that is difficult to reach. The compound is formed from “out,” meaning beyond or away from something, and “most,” meaning greatest or furthest. In formal modern prose, “outermost” is generally preferable unless a particular register, style, or historical context calls for the older alternative.

Where does outmost come from?
“Outmost” is an English compound formed from “out” and “most.” Its development parallels the more common “outermost,” which uses “outer” rather than “out.” The words “outer,” “outermost,” and “utmost” reflect the same broader Germanic and Old English roots associated with movement or position beyond something else. In modern English, “outmost” survives mainly in literary and archaic contexts, while “outermost” became the standard form.
