Etymology: "Oldermost" is a straightforward formation: the comparative "older" with the superlative-forming suffix "-most" attached. English has long used "-most" to build superlatives on words that already carry a comparative ending, so "oldermost" stands alongside "innermost" and "uppermost," where the older English form "-ermost" survives in the comparative root and the suffix adds emphasis to the superlative sense. The "-most" ending itself comes from Old English "-mest," a superlative suffix that reached its modern spelling through centuries of use. When it joins a comparative like "older," the result doubles the superlative marking, which is why the word is considered redundant by many grammarians. Dictionaries record it as a simple, transparent compound rather than a word with a dramatic backstory.
