Etymology: "Assumable" is a plain construction: the verb "assume" with the suffix "-able," meaning "capable of being" something. The suffix has a longer pedigree than the verb it attaches to. It traces back through Latin "-ābilis" and "-bilis," from a root shared with the Latin verb "habere" ("to have, hold"), and reached English through Old French "-able" in Middle English. "Assume" itself comes from Latin "assumere," meaning "to take up or take to oneself," built from "ad-" ("to") and "sumere" ("to take"). So the word's core idea is literally "taking something on," which is why "assumable" carries the sense of something that can be taken on as a given.
