Etymology: "Upmost" is a compound of "up" and "-most," the Old English superlative ending that gives the sense "furthest" or "highest" in a series. The same ending survives in "foremost," "utmost," "inmost" and "topmost," all built the same way: a directional word plus "-most" to mark the extreme point. Middle English "upmest" followed this pattern, so the word was never a single unit with a separate history of its own. The "-most" ending is itself a fossil of superlative grammar. English once formed superlatives with "-est" and, for some words, with "-m-" forms such as "-mest" and "-most." The "-most" in these compounds is therefore best understood as a superlative marker rather than a noun meaning "most." Its job is to pinpoint the outermost or highest member of a set, which explains why "upmost" and "topmost" mean nearly the same thing. Because the word is so transparently built, its meaning has changed little since the Middle English period. Its persistence is more a matter of the older compound pattern, which English largely stopped producing, than of any shift in sense.
