Definitions

Etymology: "Unrememberable" is about as plain as English coinages get: the prefix "un-", meaning "not", attached to "rememberable," which itself is "remember" plus the suffix "-able," meaning "capable of being." Put together, the word means "not capable of being remembered," and the logic of each piece is easy to check against the parts. The base verb "remember" comes from Latin "rememorari," built from "re-" (again) and "memor" (mindful), so the core idea is bringing something back into the mind. The "-able" suffix comes from Latin "-abilis" through Old French, and it has been productive in English for centuries, which is why speakers can form new adjectives like this one on demand.
