## AI Etymology
improbably comes from improbable (from Latin improbabilis, from in- 'not' + probabilis 'provable, credible', from probare 'to prove') + the adverbial suffix -ly. Morphologically, the ending is part of the etymology: the suffix is attached to the older base named in the history, producing a later English derivative. In present English, the adverb sense is "in a way that is unlikely or hard to believe", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as improbable, improbability, and probable. Its semantic neighborhood includes implausibly, unbelievably, incredibly, and unexpectedly, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Latin probabilis and Latin probare.
